John Force Racing has been dominating the motorsports world for over 30 years, winning 20 championships and hundreds of races in the National Hot Rod Association (NHRA) drag racing series. John Force Racing features both Funny Car and Top Fuel teams, and just recently in 2017 they won both the Funny Car and Top Fuel championships in the same season.

John Force Racing invested in Force American Made to develop and create parts and components that would help drive all the teams to success and safety. The 84,000 square foot shop is located in Brownsburg, Indiana (just outside of Indianapolis) and is the heartbeat of John Force Racing. Thousands of parts are forged by Force American Made and its team of employees every season giving the team a competitive edge that has led to the team’s on-track success.

The Force American Made team has relied on Helical Solutions tooling to get the best performance and quality out of their CNC mills for years. The Harvey Performance Company team was invited out to Indiana to take a tour of Force American Made and spend some time with Tom Warga, Lead Machinist, to talk with him about his experiences with Helical Solutions tooling, his first time trying Machining Advisor Pro, the success they have had using the new Helical tool libraries for Mastercam, and the value their distributor, Dolen Tool, brings to the shop. Check out the video interview below to see the inner-workings of Force American Made and how Helical Solutions tooling has contributed to the success of this motorsports dynasty.

Chipbreakers vs. Knuckle Rougher End Mills

Knuckle Roughers and Chipbreakers are common profiles found on roughing end mills that, while fairly similar in appearance, actually serve different functions. Chipbreakers refer to the notches along the cutting edge of a tool that work to break up chips to prevent common evacuation mishaps. Knuckle Roughers refer to the serrated cutting edge of a tool, which works to enhance cutting action for an overall smoother operation.

Determining the appropriate style of tool is a very important first step to a successful roughing application.

Understanding the Two Styles

Chipbreaker End Mills

To aid chip evacuation, Chipbreaker End Mills feature a notched profile along the cutting edge that break down long chips into smaller, more manageable pieces. These tools are often utilized in aluminum jobs, as long, stringy chips are common with that material.

Each notch is offset flute-to-flute to enhance the surface finish on the part. This works by ensuring that as each flute rotates and impacts a part, following flutes work to clean up any marks or extra material that was left behind by the first pass. This leaves a semi-finished surface on your part.

In addition to improving chip control and reducing cutting resistance, these tools also help in decreasing heat load within the chips. This delays tool wear along the cutting edge and improves cutting performance. Not only are these tools great for hogging out a great deal of material, but they can be utilized in a wide array of jobs – from aluminum to steels. Further, a machinist can take full advantage of the unique benefits this tool possesses by utilizing High Efficiency Milling toolpaths, meant to promote efficiency and boost tool life.

Knuckle Roughers

Knuckle Rougher End Mills have a serrated cutting edge that generates significantly smaller chips than a standard end mill cutting edge. This allows for smoother machining and a more efficient metal removal process, similar to Chipbreaker End Mills. However, the serrations chop the chips down to much finer sizes, which allows more chips into the flutes during the evacuation process without any packing occurring.

Designed for steels, Knuckle Rougher End Mills are built to withstand harder materials and feature a large core. Because of this, these tools are great for roughing out a lot of material. However, due to the profile on the cutting edge, tracks along the wall can sometimes be left on a part. If finish is a concern, be sure to come in with a finishing tool after the roughing operation. Knuckle Roughers have proven the ability to run at higher chip loads, compared to similar end mills, which makes this a highly desired style for roughing. Further, this style of rougher causes a lot of heat and friction within the chips, so it’s important to run flood coolant when running this tool.

Key Differences Between Knuckle Roughers & Chipbreakers

While the two geometries offer similar benefits, it’s important to understand the distinct differences between them. Chipbreakers feature offset notches, which help to leave an acceptable finish on the walls of a part. Simply, the material left on an initial flute pass is removed by subsequent passes. A Knuckle Rougher does not feature this offset geometry, which can leave track marks on your part. Where part finish is of upmost importance, utilize a Knuckle Rougher to first hog out a great deal of steel, and work a final pass with a Finishing End Mill.

A unique benefit of Knuckle Roughers is the grind they possess – a cylindrical grind, compared to a relieved grind of a Chipbreaker End Mill. Because of this, Knuckle Roughers are easier to resharpen. Therefore, instead of buying a new tool, resharpening this profile is often a cheaper alternative.

Nueva Precision – Featured Customer

When it comes to CNC manufacturing services and product development solutions in the Denver, Colorado area, Eddie Casanueva has quickly made a name for himself with his company, Nueva Precision. Eddie has more than 22 years of manufacturing experience and 19 years of business experience, which he uses to help small businesses and entrepreneurs who are looking for product support and development.

Eddie was able to take time out of his busy schedule to talk with us for this Featured Customer post. We covered topics like Eddie’s incredible training and introduction to manufacturing, his experiences using reduced neck end mills, and his suggestions for must-have equipment in any CNC machine shop.

Thanks for taking the time to talk to us for this Featured Customer post. To get started, tell us a little bit about the history behind Nueva Precision and what sort of products you typically manufacture.

Nueva Precision was first incorporated at the end of 2016. Within three months, I was making chips on my own, largely doing prototype work.

I had recently sold my share in another company I co-founded and used that money to move into a larger home in the Denver area that could accommodate a machine shop business. We were lucky enough to find a home with some acreage and an existing oversized garage which was perfect for a shop. Now that I had the building, I had to do things like get the electrical and HVAC up to spec. It required having the city run a stronger electrical line to the building I would use as my shop, but once that was all figured out, we were ready to make some chips.

Nueva Precision

I started by buying a used Haas mill and a used Haas lathe. People initially reached out to me for work because of my quick delivery times. I was able to turn around parts in just a week or two since the business was new. However, within a month of operating those machines, I was already at max capacity with my current equipment. Unfortunately, my lead times had increased to a more standard 4-6 weeks due to the sheer amount of work I was getting. For the rest of 2017, I stuck with my original equipment and just did the best I could to keep up.

nueva precision

Do you have any future plans to expand your shop and capabilities further?

I do! In early 2018 I brought in a brand new VM3 Haas Mill to keep up with demand, but I was curious about how much more revenue that would create. I expected to see a 20-30% increase in revenue, but having another machine ended up doubling my revenue. Luckily my strong relationships with my customers helped me grow the business even as my lead times increased. With that in mind, I just ordered another Haas VM2 at the end of 2018 and am excited to take full advantage of that.

How has your family reacted to you running a business out of your home?

My family has been extremely supportive throughout the whole process. My wife Leandra in particular helps out a lot. She was a teacher for 19 years, but resigned from that profession to work on Nueva Precision. She has started to help out on the business side of things and has also started to help run machines and make parts. My oldest son Jaden (16) is interested in manufacturing and he has started working and making simple parts for us when he is available. All in all, we have a pretty good thing going here.

How did you first get involved in CNC machining and advanced manufacturing?

I am essentially self-taught in CNC machining. I got started in engineering and manufacturing as a student at the New Jersey Institute of Technology (NJIT) in the Mechanical Engineering program. It was a state school, so tuition costs weren’t bad but I still needed to support myself. I was going to school during the day and pumping gas at night to pay the bills. In my second year in school I came across an opportunity to work at an on-campus research center for manufacturing systems. It was funded by the state of New Jersey to help promote New Jersey industry. The job didn’t have much to do with my curriculum, but they supported some campus research and worked closely with the college on various projects.

The research center had all the workings of a machine shop. There were CNC mills, lathes, injection molding machines, and more. It just looked awesome. I managed to get hired for a job at minimum wage sweeping the shop floor and helping out where I could.

As a curious student, I would ask a million questions of all the machinists and try to do more and more than the usual student employee. John – a talented toolmaker and experienced machinist – took me under his wing and taught me lots of stuff about machining. I started buying tools and building out my toolbox with him for a while, absorbing everything that I could. Next thing I know, they’re handing me prints and I am making parts. A few months down the road the machinists started teaching me programming on a Mazak controller. This went on for a year or so and I just soaked it all in.

Sounds like great experience! Where did you land your first full-time position in manufacturing?

I actually landed my first full-time job at the same manufacturing research center. The center had a CNC machinist programmer resign at the facility, so there was a job opening posted. I went to the director of the center and said I was interested in the position. I knew I had to work a lot to pay my tuition, and if I worked for the university I could get my tuition paid for while also making some real money. The director recommended me for the position, so I interviewed and landed the job. All of a sudden, I had benefits, vacation, real responsibilities, and full-time pay. I flipped my schedule around so I could go to school during nights and work during the day.

I learned so much about machining in my first job because of the unique situation I was in. Companies like Blaser Swisslube, Kennametal, and GibbsCAM were supplying us with product and support to work on process improvements for large New Jersey corporations like BF Goodrich Aerospace, US Can, etc. It progressed to the point where GibbsCAM was actually sending me to seminars to train me on different industry topics to further my education and improve the reports we were outputting.

nueva precision

I was in an amazing position to get all this training and I learned so much in the next 4-5 years. We had equipment like a Fadal 5-Axis CNC Machine and other high tech machines at my disposal, which were very hard to find at the time (mid-1990s). Nobody outside of the most elite machine shops were working in 5-axis, so I had a head start because of this unique job experience.

I actually never finished my degree and instead dove head first into manufacturing. I started my own business on the side and kept working at the research center until 2001 when I left to focus full-time on my new business, Spidertrax Offroad.

Can you tell us more about your experience with Spidertrax Offroad?

Spidertrax Offroad is a manufacturer of drivetrain parts for off-roading vehicles. I started Spidertrax with a partner whom I met in college. The company actually started making our first parts at the research center I was employed at. I asked my boss if I could start making parts off the clock on my own time, and he agreed to let me use the shop. This would have been around 1998, and by 2001 I was ready to take off on my own. My partner and I built that company up to 20 employees, and we were (and they still are) a well-respected brand in the off-roading community.

The hardest part about operating my own business and watching it grow was losing the ability to get out in the shop and actually do what I love, which is making parts. As the business grew, I had to take on more responsibility as a “business man,” and let go of many of the things I enjoyed doing as a machinist. I was very proud of what we had built, but I really wanted to get back to basics. So, in early 2017 I sold my half of Spidertrax Offroad to my partner and took that money to buy the new house and open Nueva Precision, Inc.

What sort of machines and CAM software do you have in your new shop?

Right now for CNC machines I have a 2018 Haas VM3, a 2018 Hass VM2, a 2012 Haas VF2, and a 2012 Haas TL2. I also have an engine lathe, a Bridgeport knee mill, Kaeser screw compressor, which I absolutely love, and a couple of Jet saws.

For software, I still use GibbsCAM. I have been using GibbsCAM since 1996 and have had countless hours of training and experience using it, so I think I’m a lifer.

Outside of tooling, what are some key components of your machining setup that you would recommend to others?

I started Nueva Precision without any sort of probing system in place, and using an umbrella style tool changer. I found out quickly that my time, especially being alone, is worth a lot. I highly recommend getting a solid probing system as well as a side mount tool changer. I added all of that to my VM3 and the effect was immediately noticeable. It is so much more efficient and faster.

Keeping software up-to-date is also key. It can be expensive, but it speaks for itself in just a few months. Any time I invest in technology, it seems to pay off pretty quick.

5th axis workholding

I also feel strongly about having solid workholding. I have a couple of the 5th Axis self-centering vises which are great, and a handful of Kurt vises, as well. I am also a big fan of the MMM-USA guys and their vise jaws and handles. For my shop, flexibility is key because I never know what can come through the door. I don’t do a lot of production work and spend much more time on prototype work, so flexibility is key. Having good quality workholding that I don’t need to worry about lets me swap parts in and out with ease.

As for tool holding, I ran into an issue last year where I was starting to see a lot of tool pullout and was scrapping too many parts as a result of aggressive roughing. I had to find a better solution, and I came across the REGO-FIX PowRgrip system. It might seem expensive compared to other simpler tool holder, but I think the upfront investment isn’t too bad considering the other options in that space. Again, I invested in technology, and immediately saw better results. I currently use the PowRgrip for finishing passes where I need good runout and heavy roughing where there is the highest risk of tool pullout.

REGO powRgrip

You use a lot of Helical’s Reduced Neck end mills. What are some tips or tricks you have learned by using these tools that you could share with others?

My experience with these tools is really new, but I find myself using more and more of them these days. In the beginning, I was afraid of end mills with a longer length of cut singing like crazy in the machine. I started experimenting with the reduced neck tools from Helical and was blown away by the rigidity. The tool pressure remains consistent throughout the part, so you will get the same great results on the top of the part as on the bottom.

I don’t know how many people are currently using them but it makes so much stuff possible. I have gone as large as ¾” diameter with the 5” reach and have never had an issue. Maintaining the low levels of runout is definitely key with these tools, which again comes back to having solid toolholding. Now that I have the REGO-FIX system, I am getting much better runout and plan to start pushing the reduced neck tools even harder.

helical reduced neck end mill

Most of my reduced neck end mills are the standard style, but the chipbreaker with the reduced neck has been a powerhouse for me as well. No matter what I tried with Helical’s reduced neck tooling, I have had success, so I would recommend the entire line if the situation calls for it. Just be careful with runout and make sure to double check your clearance!

What are some of your key Helical products that you use on a daily basis?

My main workhorse is Helical EDP 29422 – the ½” 45 Degree Chipbreaker for Aluminum. I swear I use that tool every single day across all of my machines. That tool is gold for me; it is night and day compared to standard roughers. It has a long enough flute length to be versatile or aggressive, depending on the situation. It is just a great tool. You will need a good holder for sure to keep it from pulling out when you get aggressive, but again my new software and tool holding helps with that.

helical solutions

Outside of performance, I love getting the smaller chips that the chipbreaker tools create. It is so much easier to clean a machine with small chips than long, stringy ones, which saves me time. I do all my roughing with chipbreakers. If you are making stringy chips while running HEM toolpaths, they can be a major pain to deal with.

My customers love the finish that Helical gives me as well. The wiper flat on the bottom of the H40ALV-3 end mill stands out as one of my favorite features on any of my tools. That tool gets me compliments on the floor finishes of pockets and enclosures all the time. Across the board, tool life and finish has been awesome with my Helical end mills. I currently use the Zplus coating for all my aluminum tools and have no complaints.

part finish

This summer I had the privilege of working on some aerospace parts that will be going up into space!  Most all parts were being machined from pre-hardened stainless steels and exotic alloys.  The Helical 5-flute and 7-flute endmills with the Aplus coating proved to be great tools to have in the arsenal.

What are your “go-to” Harvey Tool products?

For Harvey Tool, I use a lot of the full radius Keyseat Cutters to surface mill areas you can’t get to with a ball nose end mill. This saves me valuable time because I can avoid flipping the part to surface mill both sides by doing it all in one operation with the Keyseat Cutter.

keyseat cutter

Outside of the keyseats, I use a lot of miniature end mills with reduced shanks and chamfers mills in a variety of angles. I also use lollipops (undercutting end mills) to surface mill parts with hard-to-reach holes.

Overall, being able to look through a single catalog and find tons of options for neck diameters and cutter diameters is what sells me on the Harvey Tool product. It is really neat to have all those different tools available to me in one place – it’s a great catalog.

Confidently Select Your Next Thread Mill

Do you know the key differences between a Single Form Thread Mill and a Multi-Form Thread Mill? Do you know which tooling option is best for your job? This blog post examines how several factors, including the tool’s form and max depth of thread, are important to ultimately making the appropriate Harvey Tool thread mill decision.

Thread Mill Product Offering

Single Form Thread Mill

The single form thread mill is the most versatile threading solution Harvey Tool offers. These tools are ground to a sharp point and are capable of milling 60° thread styles, such as UN, metric, and NPT threads. With over 14 UN and 10 Metric sized tools, Harvey Tool’s single form selections allow machinists the opportunity to machine many different types of threads.

Single Form Thread Mills for Hardened Steels

Similar to the standard single form thread mills, Harvey Tool’s thread mills for hardened steels offer machinists a quality option when dealing with hardened steels from 46-68 Rc. The following unique geometries helps this tool machine tough alloys:

  1. Ground Flat – Instead of a sharp point these tools have a ground flat to help ensure long tool life.
  2. Eccentric Relief – Gives the cutting edges extra strength for the high feeds at relatively low RPMs required for harder materials.
  3. AlTiN Nano Coating – Allows for superior heat resistance.

A key difference between the standard Single Form Thread Mill and the Single Form Thread Mills for Hardened Steels is that the thread mills for hardened steels are actually only capable of milling 83% of the actual thread depth. At first, this may seem detrimental to your operation. However, according to the Machinery’s Handbook 29th Edition, “Tests have shown that any increase in the percentage of full thread over 60% does not significantly increase the strength of the thread. Often, a 55% to 60% thread is satisfactory, although 75% threads are commonly used to provide an extra margin of safety.” With the ability to preserve tool life and effectively perform thread components, Harvey Tool’s single form thread mills for hardened steels are a natural choice when tackling a hardened material.

Tri-Form Thread Mills

Tri-Form thread mills are designed for difficult-to-machine materials. The tri-form design reduces tool pressure and deflection, which results in more accurate threading. Its left-hand cut, left-hand spiral design allows it to climb mill from the top of the thread to the bottom.

Multi-Form Thread Mills

Our multi-form thread mills are offered in styles such as UN, NPT, and Metric. Multi-Form Thread Mills are optimized to produce a full thread in single helical interpolation. Additionally, they allow a machinist to quickly turn around production-style jobs.

Coolant-Through Multi Form Thread Mills

Coolant-Through Multi Form Thread Mills are the perfect tool for when a job calls for thread milling in a blind hole. The coolant through ability of the tool produces superior chip evacuation. These tools also improve coolant flow to the workpiece – delivering it directly from the tip of the tool – for decreased friction and high cutting speeds.

Long Flute Thread Mills

These tools are great when a job calls for a deep thread, due to their long flute. Long Flute Thread Mills also have a large cutter diameter and core, which provides the tool with improved tool strength and stability.

N.P.T. Multi-Form Thread Mills

While it may seem obvious, N.P.T. Multi-Form Thread Mills are perfect for milling NPT threads. NPT threads are great for when a part requires a full seal, different from traditional threads that hold pieces together without the water-tight seal.

Master Machine Manufacturing – Featured Customer

Master Machine Manufacturing, or MMM USA, is a family-owned and operated machine shop based out of Tulsa, Oklahoma. Master Machine is a rapidly expanding company which has seen serious growth as both a job shop and as an OEM Manufacturer of their own Quick Vise Handles and Piranha Jaws for CNC machinists.

Brothers Geordan and Nace Roberts, along with their mother, Sherry Roberts, are the owners of Master Machine Manufacturing. With Geordan and Nace, we dove into topics like having a growth mindset, working smarter instead of harder, and expanding a “job shop” business while also creating and manufacturing their own OEM products.

Tell us a little about Master Machine’s history and the type of work that your company does.

Geordan: Master Machine has been in business since 1981. Our father, George Roberts, started the business. At the beginning it was a pretty typical manual machine shop operating primarily as a job shop. As Nace and I got older, Dad introduced us to the business and we started working there part-time, eventually transitioning into full-time employees. In 1996, we transitioned to high precision machining with our first CNC machine – a Haas VF1, and we kept adding new CNC machines from there.

Nace and I took over in 2013 after our Dad passed. We had to make the transition from managers and shop foreman to owners and dealing with customers. We now own and operate the business with our mother, Sherry Roberts.

Geordan, Nace, Sherry, and the rest of the MMM USA team at IMTS with Mark Terryberry from Haas Automation

At its core, Master Machine is a job shop that does a lot of high precision machining. We work on things like lab test equipment, parts for the aerospace industry, and a lot of parts for the oil and gas industry. More medical jobs and odd things like parts for off-road racing have started to come in recently as well. One cool thing about us is that we have the unique ability to operate as a job shop, but also to design and manufacture our own products. Many of your readers have probably seen some of our vise handles and jaws in use online, especially on Instagram.

Your MMM USA Jaws and Vise Handles have become extremely popular in the CNC machining community. Where did you get the idea for that product?

Geordan: We had been using other brands of vise handles and jaws for a long time and got tired of buying products that were cheap and didn’t work well. We had this idea for a while, so in 2013 when things started to slow down a little bit, we had an opportunity to spend some time and design our own products. It was just about 2 years ago that we designed our first vise handle and Piranha Jaws. After using social media, showing them off at IMTS and other Industrial Trade Shows, they really started to take off. Our vise handles and jaws have really started to become a business of their own over the past couple of years.

vise handle

Can you breakdown the shop for us? What are you working with in terms of shop size, machine capabilities, and software?

Nace: We operate as a 100% debt-free company, so we grow as we need to. We have been at our current location for 10 years with 5-7 different additions along the way. Our shop is now spread across 10,300 square feet.

We currently have 18 CNC milling machines, including our original machine, the 1996 Haas VF1. We have been growing very fast over the past 10 years. From 2004-2007, we only had 3 CNC mills, and we have acquired the other 15 machines all in the last decade. We like buying from companies that make their products right here in the USA, so we have grown our shop through the Haas line of machines. Almost everything we own here is made by Haas Automation. In fact, our Haas VF4 and our 5-axis Haas UMC750 are some of our biggest mills in the shop right now.

Geordan: We also have other capabilities in the shop. We can do welding, painting, surface grinding, and we have a nice setup of bar feeders and lathes. For software, we use a lot of BOBCAD V31 for our 4th and 5th axis mill programming and all of our lathe programming, Nace uses a lot of Autodesk Fusion 360 for the mill side of things.

For inspection, we have many inspection tools, including a Fowler Z-Cat CMM that can measure down to +/- .0002″ for our most high precision jobs.

How did you guys first get involved in manufacturing?

Geordan: I started machining with my Dad at age 13, and got into it full-time after high school, but was not yet fully committed. At this point, I learned manual and CNC machining entirely through working with my Dad and my Uncle.  It wasn’t until my Uncle, the main machinist in our shop, decided to split off and start his own shop that I was faced with a more urgent need to commit to the family business. So I decided to make manufacturing a full time career move and started learning fixturing, programming, and everything I needed to know to be successful. We still have a great relationship with my uncle and his shop and I wouldn’t be where I am today without him stepping out on his own.

Nace: I didn’t know what I wanted to do with my life. I just knew I wanted to make money, and a lot of money. I was actually in college for radiology and physical therapy, but I didn’t like the layout of the career path. I could not convince myself to wait to start making real money until I had finished a long education and received a license 6-8 years down the road.

Instead of physical therapy and radiology, I started taking more computer engineering courses and learned a lot about programming and technology. After my uncle left, I told my Dad I would like to be a bigger part of the business and take what I knew from my computer programming classes and apply it to the shop. Within a year I had gone from never running a CNC to fully doing everything on the machine. My computer programming skills definitely helped me make the transition into CNC machining and programming.

master machine

As a second generation owner of a family business, how do you stick to those family values while also rapidly expanding the business?

Nace: We have grown a lot with our systems and technology, but our culture has also changed since we took over. We educated ourselves on workplace culture and maintaining a positive work environment. When we were kids, Dad worked probably 100 hours a week and we were always fortunate that he was able to provide us with food, clothes, and a roof over our heads. But no matter how hard he worked, he can’t replace the time with us that was spent working.

One of the major improvements we focused on was trying to maintain repeatability. Everything in the shop is labeled in boxes and readily available for our employees. Ultimately, we want to do everything we can to make it easy as possible for our employees. We want to work smarter, not harder, so there is more time for our employees to spend with family and not spend their lives in the shop.

As owners, we often need to work odd hours of the day to maintain the business, but we do it in a way that makes sure we have our family time. There are many times where we will go home, have dinner and hang out with the family, and wait until they are all sleeping to go back to work until 2 or 3 a.m.. We will get back home later that morning to sleep a little and have breakfast with the family and send them on their way before heading back in to the shop.

Working with family, we have to remind ourselves that business is business, and outside of business it is all about family. It can be tough to differentiate those two, but you have to. We went to business counseling and learned how to respect family members and build up the team while also making tough business decisions. We have our tough moments at the shop, but at the end of the day this is still your family. You can’t carry any frustration with other family members outside of those shop doors and into the home.

mmm usa piranha jaws

What are some other things you have done to maintain your “Work Smarter, Not Harder” mantra?

Geordan: One of the first things we did was look into getting more tooling and better tooling. We paid more for tools that can push harder and faster, and last longer. When Dad ran the shop, he would just buy whatever he thought we could afford and still get the job done. Now as CNC technology and advanced CAM systems have improved, the need for quality tooling is extremely important. Finding the best and most reliable tools helped take our shop to the next level and that is where Harvey Tool and Helical come into play.

Nace: We like to be the “purple cow” of the industry, differentiating ourselves in any way that we can. We strive to maintain a certain level of quality across our website, our Instagram page, our products, and the entire business as a whole. We are proud to support products made in the USA and keep supporting American manufacturing to help keep the business thriving in our shop and others. We are always happy to support companies like Haas, Harvey Tool, Helical, and many others who are doing it all right here in the USA.

What are some of your “go-to” Harvey Tool and Helical products?

Geordan: The Helical Chipbreaker End Mill for Aluminum is key for making our vise handles. We use the ½” end mill and run it at 10k RPM, 300 IPM with a .700” DOC and 40% stepover. We can push those tools harder than others while also maintaining our product’s quality. We also rely heavily on Helical’s HEV-5 for our steel applications.

One of our favorite and most-used tools is the Harvey Tool 90 Degree Helically Fluted Chamfer Mill. We use the 3-flute style on everything that isn’t Aluminum because we can simply push it faster and harder than anything else that we have tried.

master machine

Nace: We actually keep a ton of other Harvey Tool and Helical products in our Autocrib. It made sense for us to get an inventory system, and we got a great deal on a system during the recession. Industrial Mill & Maintenance Supply got us hooked up with an Autocrib and a ton of tools, and they have been great at supplying it whenever we need more. It has helped a lot having an inventory system like that. It is reassuring to know that we have the best tools ready on hand so we can eliminate any potential downtime.

Master Machine is everywhere in the online machining community, specifically on Instagram. How has online marketing and social media changed the way you promote your business?

Geordan: Most people who run businesses seem to just hope that the word of mouth gets out there, or they have a website and hope it just goes viral one day and gets some attention. With the way the Internet is so crowded these days, you have to do something more to stand out. On our side, we have boosted our business through the use of paid online advertising with Google, boosting our SEO (Search Engine Optimization) to rank higher in search results, and being heavy users of social media like Instagram.

When I started the Master Machine Instagram account, I was really just using it to see what other machinists were doing. It was actually only a personal account for my use. I was skeptical of Instagram because of the Facebook community of machinists. I always viewed Facebook as a little more negative and less productive, while the Instagram community was much more collaborative.

I started by following people like Aeroknox, Kalpay, John Saunders, Bad Ass Machinists, and Tactical Keychains. I immediately noticed how helpful everyone was. I started posting as a business just about 2 years ago, when I posted our first version of the vise handles. Almost immediately people started asking to buy them. We were blown away by the response.

We didn’t set out to create something new with these handles, but by getting our name out there and filling a need for people following us, the hype continued to grow and grow and grow. Instagram has been a great tool for that aspect of the business, especially. We now have around 15 distributors across the US who are carrying our products, and are getting some great momentum. We also sell a lot of our products direct on our website, and 99% of that probably comes through Instagram.

Nace: We have actually landed distributors through someone following us online and going to their integrated distributor asking for our products. The distributor then called us and asked if they could carry our product on their shelves. Other online connections have also helped us land distributors through simple messages and phone calls.

Where do you see MMM USA in 10 years?

Nace: That’s a tough question…

At the shop, we always stress four major actions: Define, Act, Measure, and Refine. In our eyes, there are always better ways to do things and improve our processes. We hire people to have a growth mindset, and so we are redefining our future every day through our continual improvement process. We strive to always have that growth mindset to figure out how to do a job more efficiently. With constant improvement always taking place, it is hard to nail down exactly where the shop will be in 10 years, 5 years, or even 1 year from now. One thing is for sure – we will be successful.

Geordan: Something we do want to focus on is creating new assets, exploring new ventures, and doubling in size every year. We want to continue to release new products to build out our own product line and have MMM USA distributors worldwide.

Back in the day, Kurt Workholding was just a job shop, and now they are one of the most recognized workholding brands in the CNC machining industry. It is really hard to say where this ends or goes, but we think we have a bright future as both a job shop and as a supplier of our own OEM products for manufacturing.

vise handles

Are you currently hiring new machinists? If so, what qualities and skills do you look for?

Geordan: Every Tuesday we have an open interview at 4 PM. As you can imagine, with our company’s growth, we are constantly hiring. We are looking for people that are positive that have a growth mindset who can grow within the company. We always believe we can promote from within. Most of our people have been at Master Machine for 10-15 years because we can always move people up closer to the top and help them advance in their careers as we grow.

Nace: We are really focused on finding people with good attitudes, and people who want to be here. Skilled machinists are great, but they can be rare, so attitude and fitting in with the culture is huge. We can always take a good attitude and train the skill level up, but we can’t take a good skill level and change the bad attitude. We want team members who will coach each other up and help improve the team as a whole. We love working together and supporting the business together in every aspect of the business.

master machine

What is the best advice you have ever received?

Geordan: We really like “Notable Quotables.” Here are a couple of our favorites.

“The pen is for remembering, and the mind is for making decisions.”

We only have so much brain power to make crucial decisions, so we write all the day-to-day action items down on our checklists to make sure nothing is left undone. That frees our minds up from having to remember every little piece of the business so we can save that brain power for strategic decision making moments. We must be proactive and not reactive as we lead our team.

Nace: “Your employees want to follow someone who is always real, and not always right.”

As a leader, you need to take responsibility when you screw up, and be open with the team. Let them be a part of fixing the problem, and approach every situation looking at the positive.

How to Extend the Life of Your End Mill

Breaking and damaging an end mill is oftentimes an avoidable mistake that can be extremely costly for a machine shop. To save time, money, and your end mill it is important to learn some simple tips and tricks to extend your tool’s life.

Properly Prepare Before the Tool Selection Process

The first step of any machining job is selecting the correct end mill for your material and application. However, this doesn’t mean that there should not be an adequate amount of legwork done beforehand to ensure the right decision on a tool is being made. Harvey Tool and Helical Solutions have thousands of different tools for different operations – a vast selection which, if unprepared – can easily result in selecting a tool that’s not the best for your job. To start your preparation, answer the 5 Questions to Ask Before Selecting an End Mill to help you quickly narrow down your selection and better understand the perfect tool you require.

Understand Your Tooling Requirements

It’s important to understand not only what your tool needs, but also general best practices to avoid common machining mishaps. For instance, it is important to use a tool with a length of cut only as long as needed, as the longer a tools length of cut is, the greater the chance of deflection or tool bending, which can decrease its effective life.

tool life

Another factor to consider is the coating composition on a tool. Harvey Tool and Helical Solutions offer many varieties of coatings for different materials. Some coatings increase lubricity, slowing tool wear, while others increase the hardness and abrasion resistance of the tool. Not all coatings increase your tool’s life in every material, however. Be wary of coatings that don’t perform well in your part’s material – such as the use of AlTiN coating in Aluminum (Both coating and material are aluminum-based and have a high affinity for each other, which can cause built-up edge and result in chip evacuation problems).

Consider Variable Helix & Pitch Geometry

A feature on many of our high performance end mills is variable helix or variable pitch geometry, which have differently-spaced flutes. As the tool cuts, there are different time intervals between the cutting edges contacting the workpiece, rather than simultaneously on each rotation. The varying time intervals minimizes chatter by reducing harmonics, increasing tool life and producing better results.

Ensure an Effective Tool Holding Strategy

Another factor in prolonging tool life is proper tool holding. A poor tool holding strategy can cause runout, pullout, and scrapped parts. Generally, the most secure connection has more points of contact between the tool holder and tool shank. Hydraulic and Shrink Fit Tool Holders provide increased performance over other tightening methods.

tool life

Helical also offers shank modifications to all stocked standards and special quotes, such as the ToughGRIP Shank, which provides added friction between the holder and the shank of the tool for a more secure grip; and the Haimer Safe-Lock™, which has grooves on the shank of the tool to help lock it into place in a tool holder.

Trust Your Running Parameters, and their Source

After selecting the correct end mill for your job, the next step is to run the tool at the proper speeds and feeds.

Run at the Correct Speed

Understanding the ideal speed to run your machine is key to prolonging tool life. If you run your tool too fast, it can cause suboptimal chip size, ineffective chip evacuation, or even total tool failure. Adversely, running your tool too slowly can result in deflection, bad finish, or decreased metal removal rates.

Push at the Best Feed Rate

Another critical parameter of speeds and feeds is finding the best possible feed rate for your job, for sake of both tool life and achieving maximum shop efficiency. Pushing your tool too aggressively can result in breakage, but being too conservative can lead to recutting chips and excess heat generation, accelerating tool wear.

Use Parameters from Your Tooling Manufacturer

A manufacturer’s speeds and feeds calculations take into account every tool dimension, even those not called out in a catalog and readily available to machinists. Because of this, it’s best to rely on running parameters from tooling manufacturers. Harvey Tool offers speeds and feeds charts for every one of its more than 21,000 tools featured in its catalog, helping machinists to confidently run their tool the first time.

Harvey Performance Company offers the Machining Advisor Pro application, a free, cutting-edge resource that generates custom running parameters for optimized machining with all of Helical’s products.

Opt for the Right Milling Strategy: Climb vs Conventional

There are two ways to cut material when milling: Climb Milling and Conventional Milling. In conventional milling, the cutter rotates against the feed. In this method, chips will start at theoretical zero and increase in size. Conventional milling is usually recommended for tools with higher toughness, or for breaking through case hardened materials.

In Climb Milling, the cutter rotates with the feed. Here, the chips start at maximum width and decrease, causing the heat generated to transfer into the chip instead of being left in the tool or work piece. Climb milling also produces a cleaner shear plane, causing less rubbing, decreasing heat, and improving tool life. When climb milling, chips will be removed behind the cutter, reducing your chances of recutting.

Utilize High Efficiency Milling

High Efficiency Milling (HEM), is a roughing technique that uses the theory of chip thinning by applying a smaller radial depth of cut (RDOC) and a larger axial depth of cut (ADOC). The parameters for HEM are similar to that of finishing, but with increased speeds and feeds, allowing for higher material removal rates (MRR). HEM utilizes the full length of cut instead of just a portion of the cutter, allowing heat to be distributed across the cutting edge, maximizing tool life and productivity. This reduces the possibility of accelerated tool wear and breakage.

Decide On Coolant Usage & Delivery

Coolant can be an extremely effective way to protect your tool from premature wear and possible tool breakage. There are many different types of coolant and methods of delivery to your tool. Coolant can come in the form of compressed air, water-based, straight oil-based, soluble oil-based, synthetic or semi-synthetic. It can be delivered as mist, flood, high pressure or minimum quantity lubricant.

Appropriate coolant type and delivery vary depending on your application and tool. For example, using a high pressure coolant with miniature tooling can lead to tool breakage due to the fragile nature of extremely small tools. In applications of materials that are soft and gummy, flood coolant washes away the long stringy chips to help avoid recutting and built-up edge, preventing extra tool wear.

Extend Your Tool’s Life

The ability to maximize tool life saves you time, money and headaches. To get the best possible outcome from your tool, you first need to be sure you’re using the best tool for your job. Once you find your tool, ensure that your speeds and feeds are accurate and are from your tooling manufacturer. Nobody knows the tools better than they do. Finally, think about how to run your tool: the rotation of your cutter, whether utilizing an HEM approach is best, and how to introduce coolant to your job.

 

Using Tool Libraries in Autodesk HSM & Fusion 360

The days of modeling your tools in CAM are coming to an end. Harvey Performance Company has partnered with Autodesk to provide comprehensive Harvey Tool and Helical Solutions tool libraries to Fusion 360 and Autodesk HSM users. Now, users can access 3D models of Harvey and Helical tools with a quick download and a few simple clicks. Keep reading to learn how to download these libraries, find the tool you are looking for, how to think about speeds and feeds for these libraries, and more.

Downloading Tool Libraries

To download one of our tool libraries, head to https://cam.autodesk.com/hsmtools. There you will find Harvey Tool and Helical Solutions tool libraries. You will be able to sort by vendor or use the search bar to filter results. There will be a download option for both Fusion and HSM.

From there, you will need to import the tool libraries from your Downloads folder into Fusion 360 or HSM. These tool libraries can be imported into your “Local” or “Cloud” libraries in Fusion 360, depending on where you would like them to appear. For HSM, simply import the HSMLIB file you have downloaded as you would any other tool library.

Curt Chan, Autodesk MFG Marketing Manager, takes a deeper dive into the process behind downloading, importing, and using CAM tool libraries to Fusion in the instructional video below.

For HSM users, jump to the 2:45 mark in this video from Autodesk’s Lars Christensen, who explains how to download and import these libraries into Autodesk HSM.


Selecting a Tool

Once you have downloaded and imported your tool libraries, selecting a specific tool or group of tools can be done in several ways.

Searching by Tool Number

To search by tool number, simply enter the tool number into the search bar at the top of your tool library window. For example, if you are looking for Helical Tool EDP 00015, enter “00015” into the search bar and the results will narrow to show only that tool.

Fusion 360 Tool Libraries

In the default display settings for Fusion 360, the tool number is not displayed in the table of results, where you will find the tool name, flute count, cutter diameter, and other important information. If you would like to add the tool number to this list of available data, you can right click on the top menu bar where it says “Name” and select “Product ID” from the drop down menu. This will add the tool number (ex. 00015) to the list of information readily available to you in the table.

Harvey Tool Tool Libraries

Searching by Keyword

To search by a keyword, simply input the keyword into the search bar at the top of the tool library window. For example, if you are looking for metric tooling, you can search “metric” to filter by tools matching that keyword. This is helpful when searching for Specialty Profile tools which are not supported by the current profile filters, like the Harvey Tool Double Angle Shank Cutters seen in the example below.

Fusion 360 Tool Libraries

Searching by Tool Type

To search by tool type, click the “Type” button in the top menu of your tool library window. From there, you will be able to segment the tools by their profile. For example, if you only wanted to see Harvey Tool ball nose end mills, choose “Ball” and your tool results will filter accordingly.

Tool Libraries

As more specialty profiles are added, these filters will allow you to filter by profiles such as chamfer, dovetail, drill, threadmill, and more. However, some specialty profile tools do not currently have a supported tool type. These tools show as “form tools” and are easier to find by searching by tool number or name. For example, there is not currently a profile filter for “Double Angle Shank Cutters” so you will not be able to sort by that profile. Instead, type “Double Angle Shank Cutter” into the search bar (see “Searching by Keyword”) to filter by that tool type.

Searching by Tool Dimensions

To search by tool dimensions, click the “Dimensions” button in the top menu of your tool library window. From there, you will be able to filter tools by your desired dimensions, including cutter diameter, flute count, overall length, radius, and flute length (also known as length of cut). For example, if you wanted to see Helical 3 flute end mills in a 0.5 inch diameter, you would check off the boxes next to “Diameter” and “Flute Count” and enter the values you are looking for. From there, the tool results will filter based on the selections you have made.

Tool Libraries

Using Specialty Profile Tools

Due to the differences in naming conventions between manufacturers, some Harvey Tool/Helical specialty profile tools will not appear exactly as you think in Fusion 360/HSM. However, each tool does contain a description with the exact name of the tool. For example, Harvey Tool Drill/End Mills display in Fusion 360 as Spot Drills, but the description field will call them out as Drill/End Mill tools, as you can see below.

Below is a chart that will help you match up Harvey Tool/Helical tool names with the current Fusion 360 tool names.

Tool Name Fusion 360 Name
Back Chamfer Cutter Dovetail Mill
Chamfer Cutters Chamfer Mill
Corner Rounding End Mill – Unflared Radius Mill
Dovetail Cutter Dovetail Mill
Drill/End Mill Spot Drill
Engraving Cutter/Marking Cutter – Tip Radius Tapered Mill
Engraving Cutter – Tipped Off & Pointed Chamfer Mill
Keyseat Cutter Slot Mill
Runner Cutter Tapered Mill
Undercutting End Mill Lollipop Mill
All Other Specialty Profiles Form Mill

Main Differences Between Engravers & Marking Cutters

While similar on the surface, Half-round Engraving Cutters and Marking Cutters are actually very different. Both tools are unique in the geometries they possess, the benefits they offer, and the specific purposes they’re used for. Below are the key differences between Engraving Cutters and Marking Cutters that all machinists must know, as the engraving on a part is often a critical step in the machining process.

Engravers & Marking Cutters Serve Different Purposes

All Marking Cutters are Engraving Cutters, but not all Engraving Cutters are Marking Cutters. This is because Marking Cutters are a “type” of engraving tool. By virtue of their sturdier geometry, Marking Cutters are suited for applications requiring repetition such as the engraving of serial numbers onto parts. Harvey Tool has been able to customize specific tool geometries for ferrous and non-ferrous applications, offering Marking Cutters for material specific purposes.

engraver

Engraving Cutters, on the other hand, are meant for finer detailed applications that require intricate designs such as engraving a wedding band or a complex brand design.

These Tools Have Unique Geometry Features

Historically, Engraving Cutters have been made as a half round style tool. This tool allows for a true point, which is better for fine detail, but can easily break if not run correctly. Because of this, Engraving Cutters have performed well in softer materials such as aluminum and wood, especially for jobs that require an artistic engraving with fine detail.

Marking cutters are not as widely seen throughout the industry, however. These tools hold up in harder-to-machine materials exceedingly well. Marking Cutters are a form of Engraving Cutter that contain 2 flutes and a web at the tip, meaning that the tool has a stronger tip and is less susceptible to breakage.

engraver

While these tools do not contain a true point (due to their web), they do feature shear flutes for better cutting action and the ability to evacuate chips easier when compared to a half-round engraver.

Harvey Tool Product Offering

Harvey Tool offers a wide variety of both Engraving Cutters and Marking Cutters. Choose from a selection of pointed, double-ended, tip radius, and tipped-off Engraving Cutter styles in 15 included angles ranging from 10° to 120°.

engraver

Marking Cutters are fully stocked in tip radius or tipped-off options, and are designed specifically for either ferrous or non-ferrous materials. Marking Cutters are offered in included angles from 20° to 120°.

While Engraving Cutters are offered uncoated or in AlTiN, AlTiN Nano, or Amorphous Diamond coatings, Marking Cutters are fully stocked in uncoated, AlTiN, or TiB2 coated styles.

Marking Cutters & Engravers Summarized

While both Engraving Cutters and Marking Cutters can accomplish similar tasks, each tool has its own advantages and purpose. Selecting the correct tool is based largely on preference and applicability to the job at hand. Factors that could impact your selection would be final Depth of Cut, Width of Cut, the angle needing to be achieved, and the desired detail of the engraving.

Effective Ways To Reduce Heat Generation

Any cutting tool application will generate heat, but knowing how to counteract it will improve the life of your tool. Heat can be good and doesn’t need to totally be avoided, but controlling heat will help prolong your tool life. Sometimes, an overheating tool or workpiece is easy to spot due to smoke or deformation. Other times, the signs are not as obvious. Taking every precaution possible to redirect heat will prolong your tool’s usable life, avoid scrapped parts, and will result in significant cost savings.

Reduce Heat Generation with HEM Tool Paths

High Efficiency Milling (HEM), is one way a machinist should explore to manage heat generation during machining. HEM is a roughing technique that uses the theory of chip thinning by applying a smaller radial depth of cut (RDOC) and a larger axial depth of cut (ADOC). HEM uses RDOC and ADOC similar to finishing operations but increases speeds and feeds, resulting in greater material removal rates (MRR). This technique is usually used for removing large amounts of material in roughing and pocketing applications. HEM utilizes the full length of cut and more effectively uses the full potential of the tool, optimizing tool life and productivity. You will need to take more radial passes on your workpiece, but using HEM will evenly spread heat across the whole cutting edge of your tool, instead of building heat along one small portion, reducing the possibility of tool failure and breakage.

heat generation

Chip Thinning Awareness

Chip thinning occurs when tool paths include varying radial depths of cut, and relates to chip thickness and feed per tooth. HEM is based off of the principal of chip thinning. However, if not properly executed, chip thinning can cause a lot of heat generation. When performing HEM, you effectively reduce your stepover and increase your speeds and feeds to run your machine at high rates. But if your machine isn’t capable of running high enough speeds and feeds, or you do not adjust accordingly to your reduced stepover, trouble will occur in the form of rubbing between the material and tool. Rubbing creates friction and mass amounts of heat which can cause your material to deform and your tool to overheat. Chip thinning can be good when used correctly in HEM, but if you fall below the line of reduced stepover without higher speeds and feeds, you will cause rubbing and tool failure. Because of this, it’s always important to be aware of your chips during machining.

heat generation

Consider Climb Milling

There are two ways to cut materials when milling: conventional milling and climb milling. The difference between the two is the relationship of the rotation of the cutter to the direction of feed. In climb milling, the cutter rotates with the feed, as opposed to conventional milling where the cutter rotates against the feed.

When conventional milling, chips start at theoretical zero and increase in size, causing rubbing and potentially work hardening. For this reason, it’s usually recommended for tools with higher toughness or for breaking through case hardened materials.

In climb milling, the chip starts at maximum width and decreases, causing the heat generated to transfer into the chip instead of the tool or workpiece. When going from max width to theoretical zero, heat will be transferred to the chip and pushed away from the workpiece, reducing the possibility of damage to the workpiece. Climb milling also produces a cleaner shear plane which will cause less tool rubbing, decreasing heat and improving tool life. When climb milling, chips are removed behind the cutter, reducing your chances of re-cutting. climb milling effectively reduces heat generated to the tool and workpiece by transferring heat into the chip, reducing rubbing and by reducing your chances of re-cutting chips.

 

heat generation

Utilize Proper Coolant Methods

If used properly, coolant can be an extremely effective way to keep your tool from overheating. There are many different types of coolant and different ways coolant can be delivered to your tool. Coolant can be compressed air, water-based, straight oil-based, soluble oil-based, synthetic or semi-synthetic. It can be delivered as mist, flood, high pressure or minimum quantity lubricant.

Different applications and tools require different types and delivery of coolant, as using the wrong delivery or type could lead to part or tool damage. For instance, using high pressure coolant with miniature tooling could lead to tool breakage. In materials where chip evacuation is a major pain point such as aluminum, coolant is often used to flush chips away from the workpiece, rather than for heat moderation. When cutting material that produces long, stringy chips without coolant, you run the risk of creating built-up edge from the chips evacuating improperly. Using coolant will allow those chips to slide out of your toolpath easily, avoiding the chance of re-cutting and causing tool failure. In materials like titanium that don’t transfer heat well, proper coolant usage can prevent the material from overheating. With certain materials, however, thermal shock becomes an issue. This is when coolant is delivered to a very hot material and decreases its temperature rapidly, impacting the material’s properties. Coolant can be expensive and wasteful if not necessary for the application, so it’s important to always make sure you know the proper ways to use coolant before starting a job.

Importance of Controlling Heat Generation

Heat can be a tool’s worst nightmare if you do not know how to control it. High efficiency milling will distribute heat throughout the whole tool instead of one small portion, making it less likely for your tool to overheat and fail. By keeping RDOC constant throughout your toolpath, you will decrease the chances of rubbing, a common cause of heat generation. Climb milling is the most effective way to transfer heat into the chip, as it will reduce rubbing and lessen the chance of re-chipping. This will effectively prolong tool life. Coolant is another method for keeping temperatures moderated, but should be used with caution as the type of coolant delivery and certain material properties can impact its effectiveness.

Liberty Machine – Featured Customer

Liberty Machine, Inc. is a small Aerospace and Defense-focused machine shop located out of owner Seth Madore’s garage in Gray, Maine. In just a few years, Liberty Machine has transformed from a side hustle into a full-fledged machine shop with customers all over the world.

We were given the chance to visit Seth at his shop in Maine and interview him for this post. We picked Seth’s mind about entrepreneurship, the online manufacturing community, some interesting home construction choices made to accommodate a machine shop, and more.

Thanks for having us come out and visit the shop for this Featured Customer post. To get started, tell us a little bit about Liberty Machine’s history, and what sort of products you typically manufacture.

I founded Liberty Machine, Inc. out of my garage about 6 years ago while I was still working full-time at one of Maine’s largest (and best) Aerospace and Defense shops. I was working close to around 80-100 hours a week, maintaining my full-time job as well as coming home and making chips in the evenings and weekends. At first, I was doing a lot of smaller pieces and one-off parts, such as fixtures and prototype work to help build up a customer base and make enough money to eventually upgrade my machine.

In the early years, I was using an old 1982 Matsuura MC-500 Mill that I picked up for around $6,000. I used that machine to generate enough cash flow and eventually pull the trigger on a 2015 DMG Mori Duravertical 5100 with a 4th axis, probing and high-pressure coolant which really allowed me to take on the type of aerospace and defense work I had been doing at my day job and make the leap into full time entrepreneurship in my own shop. Now, we have the capabilities to focus on aerospace and defense work for major clients all over the country.

We are still working out of my garage, with myself and one other employee, but there are hopes for further expansion in the future as we acquire more work and expand our customer base. If you want to keep up with our shop, follow us on Instagram @liberty_machine!

Liberty Machine

You have a great shop here and are definitely maximizing the space. How much square footage are you working with?

Currently, we are working out of a 940 sq/ft shop. We “technically” have room for one more CNC mill if we really squeezed things together. I don’t think that is in the cards though; it is more likely that we will move to a larger space if and when the time comes for expansion. Heat management and air quality are real issues when working in small spaces with low ceilings, which is something we deal with currently.

What sort of machines and software do you have here in the shop?

For now, we have two VMC’s and a decent amount of inspection equipment. We have the DMG Mori machine I previously mentioned, as well as a 2016 Kitamura-3XD. Both machines have 12k spindles, Renishaw probes, and feature coolant through spindles.

For inspection equipment, we have a 2014 Mitutoyo QM-Height 350 Digital Height Gage, a 2003 Brown & Sharpe Gage 2000 CMM with Renishaw MIP Articulating Probe Head, and a 2003 Mitutoyo PH-A14 Optical Comparator. We also recently acquired a Scienscope Stereo/Digital microscope. This allows us to perform visual inspection of our parts at an extreme amount of detail.

Liberty Machine

There are still holes in our inspection lineup, so we are always looking at adding onto what we do to provide our customers with quality machined products.

For CAD/CAM software, we use Autodesk’s Fusion 360 as well as Inventor HSM.

You mentioned using Fusion 360 for CAD/CAM. Some of our readers may know you from the Autodesk CAM forums as an “Autodesk Expert Elite.” How did that come together?

About 4-5 years ago, I knew I needed a legal, supported, capable CAM solution. After several “30-day trials” of the more affordable packages, I stumbled upon Fusion 360. Having a fair amount of experience with Esprit and MasterCAM, I taught myself Fusion 360 in between running my shop and trying to spend what little time I had with my wife and children. Even though I had prior experience in other CAM packages, I still had lots of questions. I turned to the Fusion CAM Forums for assistance. The employees and other users were excellent to work with and got me sorted out quickly.

Liberty Machine

After I became more comfortable with the Fusion 360 software, I decided to spend some of my free time helping others by answering their questions on the forums. I wanted to give back to the community that had helped me learn. Autodesk eventually took notice of my constant presence on the forums and granted me the title of “Autodesk Expert Elite,” an honor given to some of their most prolific community members and advocates. Now I work with them to help test new features, provide insight from a user’s point of view, and participate in events like Autodesk University.

How did you first get involved in manufacturing?

I will be honest – I never meant to end up working in manufacturing. When I was a teen, I had glamorous ideas about law enforcement, federal work and so forth. But, life doesn’t always work out that way (I met a wonderful girl and goals shifted, so I started looking for alternate career paths).

My friend (future brother-in-law) was a machinist, so I started asking about his work and what it involved. He was working in a “job shop” using all sorts of cool machines and technology I had never really heard about. I was very excited about this career shift and I pursued it with fervor. 19 years later and I still LOVE this trade. The thing that intrigued me most about manufacturing, and the real reason I became so fixated on the trade, was the integral role the machinist plays in every aspect of manufactured society. I believe it is the most fundamental profession there is, and I take great pride in it. The evolution of the trade from manual machining to skilled programmers running CNC machines has always fascinated me as well and has kept pushing me to learn more and continue growing as a machinist.

Is it true that you built an addition to your garage specifically for the DMG Mori machine?

That is true! Before I bought the machine, I knew it was going to be too tall for my existing space, and was also going to need a solid foundation to sit on (it weighs 7 tons). Before the machine arrived, I had a concrete slab poured right against the side wall of the existing garage, and placed the DMG Mori on that slab.

After a couple days of unfortunate rain and multiple layers of tarps covering the machine, I had several family members (carpenters by trade) help me build the addition. Ok…I helped them. They were able to get it all framed and covered in just one day, breaking down the side wall of the garage and literally building the new space around the dimensions of the machine. Like they say, if there is a will, there is a way!

Running a shop out of your garage must have been a challenge to startup. What were some of the growing pains you experienced as this shop was built out?

On a professional level, the struggle was real. Two jobs, huge payments on the horizon, wondering where all the work (and money) is going to come from… As I mentioned, at that point, I was working 100 hours a week between the two jobs, and really feeling wiped out at the end of each week. However, the hard work did eventually pay off. Once I was able to get the DMG Mori and prove to customers that I had the capabilities to go full-time on my own, it was all worth it.

Outside of that, there were the literal growing pains, like cutting holes in my garage ceiling to fit the column on the Kitamura machine, and of course, building an addition to house the DMG. But like I said, it was all worth it in the end to own my own shop.

What is the best thing about working for yourself?

I’d say the best thing about working out of my shop (and for myself) is seeing my family on a daily basis. Yes, I still work 60-70 hours a week, but to have breakfast with them each morning before our day starts and have the flexibility to shift schedules around for doctor visits and other “life stuff” is worth its weight in gold. We are all so busy in life and I think we suffer as a society because of it. I want my children to know what it’s like to have a parent that is around. Busy, yes. But still present.

You mentioned that you had used a lot of Harvey and Helical tools at your last job. However, once you were on your own, you could choose any tooling you wanted to use. What made you stick with the Harvey Performance Company brands as your go-to tools?

The thing with Harvey Tool and Helical products that keep me coming back is the consistency of quality. I know that when I buy one of these tools, I am going to get a high-performing tool that has gone through multiple levels of inspection and is consistently ground within the tight tolerances that were promised. I honestly cannot remember a single time I have had to send any Harvey or Helical tools back for quality issues.

I tell friends and others in the manufacturing community about the tools, and the hurdle is always getting them to look past the slightly higher cost. That additional cost is always worth the payoff in the end knowing that you have a tool that will produce quality parts and shave valuable minutes off your cycle times. The slightly higher cost of the Harvey/Helical product is small change compared to the long term cost savings associated with their performance.

Can you remember a key moment where Harvey Tool/Helical products really saved the day?

Truthfully, Harvey and Helical are my first thought when I’m looking at a challenging feature on a new part. If they offer something that looks like it will work, I don’t even look for an alternative. Order it, get it in house. I’d say where Harvey helps the most is their awesome selection of long reach/stub flute end mills for stainless steel. I cut so much of that, so it’s great to have a vendor stock what is truly needed.

Would you recommend entrepreneurship to other young machinists hoping to open their own shop some day?

Yes! But like all things in life, “It depends.” Entrepreneurship is certainly not for everyone. The amount of work required to get a shop rolling and out of “crisis-mode” is insane. There is no other term for it. If you have a significant other in your life, MAKE SURE they are on the same page as you. I am blessed to have a wife by my side who sees the end goal and is understanding of the sacrifice needed in the short-term for the long-term benefit of our family.

What advice might you want to give to someone starting in this trade?

Don’t stop learning. Keep your ears open and your mouth shut. That old guy in the shop has likely forgotten more than you will ever learn. The amount of tools in your Kennedy box doesn’t mean you’re a good machinist. Some of the best toolmakers I knew had small boxes with only the common tools. Learn how to excel with limited resources. Ask questions, and own up to your mistakes.
