Save Time With Quick Change Tooling

Making a manual tool change on any CNC machine is never a timely or rewarding process. Typically, a tool change in a standard holder can take up to 5 minutes. Add that up a few times, and suddenly you have added significant minutes to your production time.

As CNC machine tool and cutting tool technology has advanced, there are more multi-functional tools available to help you avoid tool changes. However, sometimes it just isn’t feasible, and multiple tool changes are needed. Luckily, Micro 100 has developed a revolutionary new method to speed up tool changes significantly.

What is the Micro-Quik™ Tooling System?

Developed in Micro 100’s world-class grinding facility in Meridian, Idaho, the Micro 100 Micro-Quik™ tooling system is held to the same standards and tight tolerances as all of the Micro 100 carbide tooling.

The quick change tooling system allows for highly repeatable tool changes that save countless hours without sacrificing performance. This system combines a unique tool holder with a unique tool design to deliver highly repeatable and accurate results.

Each quick change tool holder features a locating/locking set screw to secure the tool and a locating pin which helps align the tool for repeatability. Removing a tool is as simple as loosening the set screw and inserting its replacement.

During tool changes, the precision ground bevel on the rear of the tool aligns with a locating pin inside the tool holder. The distance from this locational point to the tip of the tool is highly controlled under tight tolerances, meaning that the Micro-Quik™ tooling system ensures a very high degree of tool length and centerline repeatability. The “L4” dimension on all of our quick change tools, as seen in the image above, remains consistent across the entire product line. Check out the video below for a demonstration of the Micro 100 Micro-Quik™ system in action!

Quick Change Tooling Benefits

The most obvious benefit to using Micro 100’s Micro-Quik™ system is the time savings that come with easier tool changes. By using the quick change holders in combination with quick change tooling, it is easy to reduce tool changes from 5 minutes to under 30 seconds, resulting in a 90% decrease in time spent swapping out tools. This is a significant benefit to the system, but there are benefits once the tool is in the machine as well.

As mentioned above, the distance from the locational point on each tool shank to the tip of the tool is highly controlled, meaning that regardless of which type of tool you insert into the holder, your stick out will remain the same. This allows you to have confidence in the tooling and does not require additional touch offs, which is another major time saver.

By removing additional touch-offs and tool changes from your workflow, you also reduce the chances for human or machine error. Improper touch-offs or tool change errors can cause costly machine crashes and result in serious repairs and downtime. With the Micro 100 Micro-Quik™ system, initial setups become much easier, allowing you to hit the cycle start button with total confidence for each run.

By making a few simple changes to your tool holding configurations and adopting the Micro-Quik™ system, your shop can save thousands in time saved, with less machine downtime and increased part production.

KAD Models – Featured Customer

Established in 2012, KAD Models is a small, yet steadily growing prototype machine shop, which originated in the San Francisco Bay Area and has since opened its second location in Vermont. They have been a regional leader in the advanced manufacturing space for many years, and operate in close connection with other machine shops and related businesses like turning facilities, anodizers, welders, and more. KAD Models staff is comprised of diverse occupational backgrounds (e.g. mechanic, industrial engineer, blacksmith, etc.). Further, they have invested into their local community college and technical training programs to support an expanding talent pipeline for advanced manufacturing.

Brian Kippen is the owner & founder of KAD Models & Prototypes, Inc. Before launching KAD with model maker John Dove, Brian worked as the Director of Operations at A&J Product Solutions and a machinist at Performance Structures. Brian is drawn to the challenge of making design concepts into reality, and motivated by the ever-changing landscape of machining. Brian took time to speak with us about KAD Models, his experiences, machining techniques, and so much more.

Can you give us a little background on how KAD Models was started?

I worked for a few years repairing automobiles, then following high school, I attended college for about three weeks. After some strong encouragement from my mom, I moved out west. I joined the Marines, broke both of my feet, and was honorably discharged. Then, I got my broken foot in the door at a machine shop and knew what I wanted to be when I grew up. After years of working as a machinist, I went into business with one of my previous employers. After a year and a half, the partnership degraded and I made the decision to buy out my partner.

It’s been really gratifying to see the business grow and get to know different types of customers as the shop’s reputation spreads. One of the reasons I wanted to start my own shop is that I really wanted to see the industry evolve in a new way, to better meet people’s needs. It’s been really great to see that decision and the investments I’ve made in building KAD pay off.

We produce approximately $1.5M of parts for 100+ distinct clients each year.  Since its founding in 2012, KAD has continued on a steady path of growth, adding staff, equipment, and clients without marketing or advertising. We build a broad range of products such as automotive drive axles, silicone cardiovascular valves, and fully functional consumer product models. Due to the nature of prototyping, no component is outside of the realm of possibility. 

What machines are currently in your shop?

We use Haas CNC machines. At our West coast facility, we have six machines, five vertical 4 AXIS machining centers with capacities up to 26” Y AND 50” X and one 5 AXIS universal machining center. At our East coast facility, we currently have two new CNC ONE 3 AXIS and one 5 AXIS universal machining center paired with a Trinity Automation AX5 robotic cell. I decided to get a 5 axis milling machine earlier last year because I felt we should invest before the absolute necessity arose. I’m excited about the creative options it opened up and it’s been fun to put it to good use. We are currently using both Fusion 360 and Surfcam software.

What sets KAD Models apart from the competition?

Our quick turnaround time of 3-5 days with our ability to tackle very complex parts sets KAD apart from a majority of manufacturers.

I also think our willingness to really dig in with the client and get to know what they need and why. We have a really creative team here at KAD and thrive at not only building complex parts, but helping industrial designers and engineers think through manufacturing, design, and usage requirements to build the simplest, most effective product we can. I’ve created prototypes before, just from a conversation with someone – not even a CAD drawing. It’s these types of interesting challenges that made me want to be a machinist in the first place and that keeps me engaged and excited day-to-day.

KAD Models is an innovative company. Can you speak about what innovations KAD makes?

Well, KAD works with some of the most innovative companies out there, across all kinds of industries: medical devices, aerospace, automotive, and consumer electronics. We help people at the forefront of innovation bring their ideas to life, so I’d say innovation is basically our bread and butter. As far as our innovations in process, as I said before, KAD has a really creative team. Since we are well known for prototyping and since prototype manufacturing need not follow all the common work holding rules, we break them on a daily basis.

What is your favorite part of your job?

I love the challenge of taking on seemingly impossible ideas and turning them into tangible things. I’m really satisfied when I can come home after a long day and have held the things I’ve made in my hands. I’m also really proud to be a business owner. It’s incredibly rewarding to see a team you’ve taught and grown to take on and be inspired by the same types of problems as you. It’s been really cool to see what we’ve been able to accomplish for our clients. My personal passion remains automotive.  KAD has reverse-engineered many no longer available automobile components and designed parts that upgrade vintage Datsuns.

Why is high-quality tooling important to you?

In prototyping, you often get one chance in order to make deadlines. High quality and high-performance tools allow you to get this done without question. Given 95% of our tooling is either Helical or Harvey, I would say that high-quality tooling helps us out on a daily basis. We also use High Efficiency Milling (HEM) techniques, which Helical is optimized for. We find with long cutters and with deep pockets, HEM is almost a must.  Often though, on shallow areas, it’s overkill.  As with salt, there can be too much. 

If you could give one piece of advice to a new machinist what would it be?

Fail fast and fail often. Then learn from your mistakes. 

I think the biggest thing is getting to know other machinists, learning other methods, and being open to alternative ideas. It’s important to keep your mind open because there’s always more than one way to machine something. One of the things I’ve found most rewarding about running my own shop is getting to set the tone of how we work with other shops and adjacent industries. I’m really passionate about the manufacturing community as a whole and I’m glad blogs like this exist to help draw connections amongst us.

Also, don’t be afraid to challenge the status quo. I love working with new machinists because they bring different ideas to the table. That’s really important for innovation and to keep us all moving forward.

Machining Advisor Pro Updated With New Improvements

Harvey Performance Company is excited to announce that Machining Advisor Pro, a cutting edge resource for generating custom CNC running parameters, has been updated with new features and improvements with the release of version 1.5.

Thousands of users have enjoyed the benefits of using Machining Advisor Pro (MAP) to dial in their running parameters for their Helical Solutions high-performance end mills, and with version 1.5, the Harvey Performance Company team has made customizing your speeds and feeds easier than ever. Much of the work done on MAP version 1.5 was the direct result of excellent user feedback, including some of the most innovative updates to the user experience since the launch of Machining Advisor Pro in 2018.

The new improvements to MAP include:

Improved Speed and Feed Sliders (Desktop)

The speed and feed sliders in the “Recommendations” section are now percentage-based. This allows users to more precisely adjust their running parameters while fine-tuning numbers for increased production or longer tool life. Previously, users could adjust their speed and feed values with dials, but without an exact measurement of the increase or decrease. With the new sliders, users can be more accurate, adjusting their speed and feed values by +/- 20% in one percent increments. Users can also type in percentage values to automatically adjust the sliders to their desired number.

machining advisor pro

Locking Depths of Cut

Inside of the “Parameters” section, users will now see a new button that allows them to lock their depths of cut. With this new feature, users have more control over the customization of their running parameters. In the past, the radial and axial depths of cut would adjust dynamically with each other based on the user adjustments to one of the values. Now users can lock the radial depth of cut (RDOC) and adjust the axial depth of cut (ADOC) without affecting the RDOC value, and vice versa.

Machining Advisor Pro Update

Enhanced Summary Section (Mobile)

On mobile devices, users will now see an enhanced “Summary” section at the completion of their job. The summary section will now include key metrics like material removal rate (MRR), as well as important parameters that apply to trochoidal slotting toolpaths. The summary section for chamfering toolpaths has also been updated to better reflect the necessary parameters for those tools.

Machining Advisor Pro Mobile

Smoother User Experience

In MAP version 1.5, users will be greeted with a much smoother user experience throughout the application. Due largely to user feedback, the Harvey Performance Company team has been hard at work to make sure that the major pain points within the application have been addressed. Much of the feedback centered around the “Tooling” section and the “Material” section and significant improvements have been made to each.

In the tooling section, MAP will now automatically select a tool for you if you enter a valid EDP once you navigate outside of that section. If an invalid EDP number is entered, the intrusive error message has been removed and now will display “no results found” in the drop-down menu.

In the material section, MAP requires that a material condition be selected in order to generate accurate running parameters. In the past, this was not immediately clear and could lead some users to believe that the application was malfunctioning. In version 1.5, once a user leaves the material section without selecting a condition, a message will display in the material section to alert users of the missing material condition.

Open in MAP from HelicalTool.com

On the new HelicalTool.com website, users can now import a tool into MAP from the Tool Details page. Users reach the Tool Details page by clicking on a SKU in a product table, or searching for an EDP in the search bar. Once on the Tool Details page, users can select “Open in Machining Advisor Pro” under the Resources section, and MAP will open in a new window and import the tool’s information directly into MAP.

Helical Machining Advisor Pro


Users will see these updates immediately upon their next log-in to the application on a desktop computer and will need to ensure their app is updated to the latest version from the App Store or Google Play to see these changes reflected on mobile.

How to Advance Your Machining Career: 8 Tips from Machining Pros

Since we began shining a light on Harvey Performance Company brand customers via “In the Loupe’s,” Featured Customer posts, more than 20 machinists have been asked to share insight relevant to how they’ve achieved success. Each Featured Customer post includes interesting and useful information on a variety of machining-related subjects, including prototyping ideas, expanding a business, getting into machining, advantages and disadvantages of utilizing different milling machine types, and more. This post compiles 8 useful tips from our Featured Customers on ways to advance your machining career.

Tip 1: Be Persistent – Getting Your Foot in the Door is Half the Battle

With machining technology advancing at the amazing rate that it is, there is no better time to become a machinist. It is a trade that is constantly improving, and offers so many opportunities for young people. Eddie Casanueva of Nueva Precision first got into machining when he was in college, taking a job at an on-campus research center for manufacturing systems to support himself.

“The research center had all the workings of a machine shop,” Eddie said. “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… John – an expert 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.”

One of the best things about becoming a machinist is that there is a fairly low entry barrier. Many machinists start working right out of high school, with 12-18 months of on-the-job training or a one to two year apprenticeship. Nearly 70% of the machinist workforce is over the age of 45. The Bureau of Labor Statistics is predicting a 10% increase in the machinist workforce with opportunities for 29,000 additional skilled machinists by 2024, so it is certainly a great time to get your foot in the door.

Tip 2: Keep an Open Mind – If You Can Think of It, You Can Machine It

Being open-minded is crucial to becoming the best machinist you can be. By keeping an open mind, Oklahoma City-based company Okluma’s owner Jeff Sapp has quickly earned a reputation for his product as one of the best built and most reliable flashlights on the market today. Jeff’s idea for Okluma came to him while riding his motorcycle across the country.

“I had purchased what I thought was a nice flashlight for $50 to carry with me on the trip. However, two days in to the trip the flashlight broke. Of course, it was dark and I was in the middle of nowhere trying to work on my bike. I’m happy to pay for good tools, but that wasn’t what happened. Not only was there no warranty for replacement, there was no way to fix it. It was just made to be thrown away. That whole attitude makes me angry. When I got home, I decided I was going to put my new skills to work and design and build my own flashlight, with the goal of never running into an issue like I had on my trip ever again. I started by making one for myself, then four, then twenty. That was four years ago. Now I have my own business with one employee and two dogs, and we stay very busy.”

An awesome side benefit to working as a machinist is that you have all the resources to create anything you can dream of, like Jeff did with Okluma.

Tip 3: Be Patient – Take Time to Ensure Your Job is Setup Correctly before Beginning

The setup process is a huge part of machining, but is often overlooked. Alex Madsen, co- owner of M5 Micro in Minnesota, has been working in manufacturing for more than 11 years. Alex is also a part owner of World Fabrication, and owns his own job shop called Madsen Machine and Design. Alex has spent countless hours perfecting his setup to improve his part times.

“It is certainly challenging to use little tools, but the key is to not get discouraged. You should plan on lots of trial and error; breaking tools is just a part of the game. You may buy ten end mills and break six, but once you dial one in it will last the rest of the job.

You should also make sure to put extra time and effort into understanding your machine when working on micromachining jobs. You need to know where there is any backlash or issues with the machine because with a tiny tool, even an extra .0003” cut can mean the end of your tool. When a difference of one tenth can make or break your job, you need to take your time and be extra careful with your machine, tool inspection, and programming before you hit run.”

Tip 4: Effort Pays Off – Long Hours Result in Shop Growth

Success isn’t earned overnight. That is especially true in the machining world. Becoming a good machinist takes a great deal of sacrifice, says Josh from Fleet Machine Co. in Gloucester, MA.

“Opening your own shop involves more than learning how to program and machine. You also need to be willing to sacrifice some of your free time by working long hours to build your business from the ground up. Being a great machinist is important, but you also need to understand the basics of business, and you need to be able to sell your service and maintain a certain level of quality to keep your customers coming back.”

Working hard is a common theme we hear from our featured customers. Brothers Geordan and Nace Roberts of Master Machine Manufacturing have similar advice.

“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 two or three 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 into the shop.” Starting and growing a business takes time. Every machinist starts from the beginning and through hard work and determination, grows their business.

Tip 5: Utilize Tooling from Quality Manufacturers – All Tooling Isn’t Created Equal

 

When it comes down to it, tooling is singlehandedly the biggest choice you will make as a machinist. Grant Hughson, manufacturing engineer at Weiss Watch Company who works as a manufacturing instructor in his spare time, reflected on the importance of tooling.

“Tool to tool accuracy and performance is vital in this business, especially with our extremely tight tolerances. High quality tools make sure that we get the same performance time after time without needing to scrap parts. This saves us valuable time and money.”

While opting for cheaper tooling can appear to be beneficial when just starting out, before long, machinists are losing time and money because of unpredictability. Jonathan from TL Technologies echoed this point, saying:

“We feel that if we invested so much in these high-end machining centers, it would be criminal to put insufficient tooling and holders into them. We found that by selecting the proper tool with the appropriate sciences behind it we have been able to create products with a cost per cut that is not only competitive, but required to stay current. By keeping the quality as high as possible on the part making side of things, we’ve insured as much ease and reliability into our downstream process as we could. Quality tooling also provides predictability and added safety into the workflow. High-quality carbide tooling is the lifeblood of the business.”

Additional Thoughts Regarding Boosting Your Machining Career With Tooling:

Don’t Cheap Out

  • “The 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” – Seth, Liberty Machine

Consistency is Key

  • “We know the performance we are going to get from the tools is consistent, and we can always rely on getting immaculate finishes. While using the Harvey Tool and Helical product, we can confidently walk away from the machine and come back to a quality finished part every time.” – Bennett, RIT Baja SAE

Superior Specialty Tools

  • “One of the greatest things that I’ve experienced over the past year and a half is flexibility. We’ve asked for some specific tools to be made typically, the lead times that we found were beyond what we needed. We went through the Helical specials division and had them built within a couple of weeks. That was a game changer for us.” – Tom, John Force Racing

“Having high quality tooling like Helical is essential. Helical tools help us maintain a much higher machining efficiency because of the outstanding tool life, while also achieving more aggressive run times. In addition, we are able to consistently keep high tolerances, resulting in a better final product.” – Cameron, Koenig Knives

Tip 6: Get With the Times – Join the Social Media Community

Social media is a valuable tool for machinists. With ever-increasing popularity in networks such as Facebook, LinkedIn, Twitter, and Instagram, there will always be an audience to showcase new and unique products to. We asked a few of our featured customers how they incorporated social media into their machining and the benefits that come along with it.

“A lot of our sales come through Instagram or Facebook, so I would recommend those platforms to anyone who is trying to start a business,” Jeff from Okluma said. “We have also had a lot of success collaborating with others in the community. Typically it is something we couldn’t do ourselves, or they couldn’t do themselves, so we share the labor and collaborate on some really cool items.”

Tip 7: Value Your Customers – Always Put Them First

“In the Loupe’s” featured customers repeatedly emphasized the importance of putting customers first. It’s a simple concept to master, and pays off immensely. Repeat customers tell you that you are doing something right, said Brian Ross, owner of Form Factory.

“We have kept our customers happy and consistently deliver parts on time, so we get a lot of repeat business. Word definitely gets around on how you treat people so we try to treat everyone with respect and honesty which is key to running a good business.” Jeff from Okluma takes great pride in his customer service, saying “we only sell direct to consumers through our website so we can control our lifetime warranty. It has worked really well for us so far, so we have no plans to change that right now. I care more about our customers than any retailer is able to.”

Tip 8: Never Stop Learning – Ask Questions Whenever You Can

Hopefully some of these tips from our featured customers stuck with you. To leave you with a quote from of Seth Madore, owner of Liberty Machine, “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.”

Okluma – Featured Customer

Okluma is a small manufacturing business located in Oklahoma City focused primarily on creating high-quality flashlights that can stand up to the most extreme conditions. The company was founded in early 2015 out of owner Jeff Sapp’s garage, and has quickly gained a solid reputation as one of the best-built and most reliable flashlights on the market today.

We were able to steal a few moments of Jeff’s time to interview him for this Featured Customer post, where he shared his thoughts on topics like the importance of customer service, the reason to use higher quality tooling, and his transition into the world of CNC machining.

To get started, how did you first get involved in manufacturing?

In high school I actually worked in a machine shop. This is where I got my first exposure to big machines and manufacturing. I worked at the shop until I graduated, doing simple things like sweeping the floor and running errands. The work wasn’t very exciting, but it did give me some really good exposure to the world of machining. Every now and then one of the machinists would let me help out with a part, but that would be rare. I did manage to save up enough money to buy a small mill and lathe, which I took with me when I went off to college.

During college and after graduation, I made a living by writing software, which I did successfully for 15 years. Eventually I got tired of writing software after I had spent more than a decade in that space, and I wanted to try something new. I had picked up small jobs and worked on personal projects over the years, so I decided to enroll in a machine shop school in Oklahoma City to learn more about manufacturing and becoming a machinist, and graduated from there with a renewed sense of what I wanted to do. Technical schools are a great way to pick up new skills and advance your career. The manufacturing technology program at the Francis Tuttle Technology Center here in Oklahoma City was great and the instructors there, Dean and Julia, are talented and very patient people.

okluma

Did your background in writing software help you transition into CNC programming?

Absolutely. It was a tremendous help to understand some very strange programming concepts that came with writing software, and it all translated very well into CNC programming. These days, CNC machinists and programmers need to be as knowledgeable about the software and programs as they do the tools and parts, so having a background in software programming or development certainly translates well to the world of CNC machines.

Where did the idea to start Okluma stem from?

After graduation from the machine shop program, I took a few weeks off and went on a long, off-road motorcycle trip across the country. I had purchased what I thought was a nice flashlight for $50 to carry with me on the trip. However, two days in to the trip the flashlight broke. Of course, it was dark and I was in the middle of nowhere trying to work on my bike. I’m happy to pay for good tools, but that wasn’t what happened. Not only there was no warranty for replacement, there was no way to fix it. It was just made to be thrown away. That whole attitude makes me angry.

When I got home, I decided I was going to put my new skills to work and design and build my own flashlight, with the goal of never running into an issue like I had on my trip ever again. I started by making one for myself, then 4, then 20. That was 4 years ago. Now I have my own business with one employee and two dogs, and we stay very busy.

What does your current product offering look like?

For our products, I currently have two flashlights models (the DC1 and DC2) and we are working on some cool new projects for 2019. With battery and LED technology advancing like it has, there are some interesting applications, way beyond just flashlights, that haven’t been possible until recently. Stay tuned for more information on those by following us on Instagram.

What do you think separates an Okluma flashlight from the competition?

The basic values behind Okluma all stem from me simply wanting a nice tool that won’t break easily and will be supported by the manufacturer. I offer a lifetime warranty and stand firmly behind that. I want an Okluma flashlight to last forever so you will never have to buy another flashlight.

The quality and hardiness of a flashlight is important to many outdoors types, homeowners, and collectors, but we also sell lots of our flashlights to the military and police. If their light goes out in a tough situation it could be really bad, so we have to make sure our flashlights can be dependable above all else. Like they always say, you get what you pay for. Our flashlights aren’t going to be the cheapest, but we stand behind them with our warranty and pride ourselves on the quality and reliability.

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

Right now I have the old standards like a Bridgeport mill and an old LeBlond lathe, as well as my CNC machines – a Daewoo Lynx 220LC CNC Lathe and a Doosan DNM 4500 CNC Mill.

For software, I use Autodesk Fusion 360 for the mill, and I write the G-code by hand for the lathe. I was more familiar with the lathe, so I had an easier time writing my own code for it. Getting Fusion 360 for my milling has been a huge help.

Have you been using the Harvey Tool and Helical Solutions tool libraries in Fusion 360?

Yes! The tool library in Fusion 360 was a huge help for me. To be able to get the right tool and not model things incorrectly probably saved me a lot of broken tools. That was a big reason why I came to Harvey Tool and Helical for support in the first place.

It was cool to come from the software community, where we collaborated on a lot of open-source projects, and see companies like Autodesk opening up their software to manufacturers like Harvey Tool and Helical for these great partnerships.

What sort of operations/parts do you create on the lathe versus the mills?

As you can imagine (being a cylindrical shaped part) most of the flashlight manufacturing is done on the lathe. For a while I had been making them all by hand, until we got the CNC lathe. While most of the work is done on the lathe, for the more intense pieces we have to drill and tap and do some different slotting operations. We also drill and tap the clip holes for all of the flashlights, so the CNC mill is huge for those operations.

As Okluma started to grow, we realized that we had a huge bottleneck doing our secondary operations by hand on the manual milling machine. We solved that problem by buying the Doosan mill to help with secondary operations, but you still have to know how to use it to make it worth the purchase!

I was completely in the dark on the CNC milling side of things at that time, as I was much more familiar with the lathe. I actually called Harvey Tool with a few questions, and the Harvey Tech team really held my hand and walked me through all of the things I needed to know, which was huge. I also used the Machining Advisor Pro application to generate speeds and feeds for my Helical end mills. MAP helped save me a lot of broken end mills and increased my production times.

You are using almost exclusively Harvey Tool and Helical for milling operations on your Doosan VMC. Why is purchasing quality tooling important to you?

I can try to do things on my own and eventually get it, but it costs me money on broken tools and it costs me my time, which is even more valuable. I could go that route with any number of different tooling manufacturers, but the fact that I can call Harvey or Helical and get an answer to my questions the first time, usually in a few minutes, and know it will work is hugely helpful. I don’t really look at the cost of the tools so much, because I just know they work and I know I will get the support I need to make my milling operations a success.

Can you remember a crucial moment when Harvey Tool or Helical technical support helped you to be more productive?

As we try to get more creative with our designs, we plan to rely heavily on Harvey and Helical to explore some of these new applications. We actually build our own tool to work on the flashlights, and we are using Harvey and Helical exclusively to machine that. At first, I was making the tools in two operations; I was doing a radius on top and then flipping the part over to create a radius on the bottom. I was having a hard time lining it up. We moved the second radius on the first operation, and used an undercutting tool and everything matched up perfect. I wasn’t really sure how to do it, but I called you guys and you figured it out with me! We have some cool projects coming up which we are planning to rely on Helical tools for, but people will have to stay tuned for that one!

What have been some of your keys to success for your growing sales?

Good customer service is key. We are one of the few companies that will offer a lifetime warranty. I know there are a lot of flashlight collectors, and we can make fun stuff for those guys, but I want people to really use our flashlights and scratch them and do ridiculous things with them. We have had people use a flashlights in crazy ways (like as a hammer) but we will still fix them under our lifetime warranty. I don’t really care what people do to our flashlights, I just want them to always work.

We can also overnight replacement flashlights for professionals who rely on them for work, so they never have to be without one. That is huge for our customers in the military or in law enforcement who rely on our flashlights as an essential tool in their day-to-day lives.

Do you have plans to expand into retailers, either online or brick and mortar stores?

We only sell direct to consumers right now through our website so that we can control our lifetime warranty. It has worked really well for us so far, so we have no plans to change that right now. I care more about our customers than any retailer is able to.

I’ve noticed that you have gathered a rather large social media following. How has social media helped shape your business?

A lot of our sales come through Instagram or Facebook, so I would recommend those platforms to anyone who is trying to start a business. We have also had a lot of success collaborating with others in the EDC (Every Day Carry) community where makers are creating knives, wallets, keychains; anything you would carry on you “every day”, hence the name. We have collaborated to make flashlights out of other people’s materials, let other shops refinish our flashlights, and things of that nature. Typically it is something we couldn’t do ourselves, or they couldn’t do themselves, so we share the labor and collaborate on some really cool items.

I think social media is especially great for manufacturing because a lot of younger people don’t even know all this crazy cool stuff that is going on in the industry. I was lucky enough to see it first hand at a young age, but so many others never get the chance. It is awesome to share our work and try to inspire some of the younger generation to make their own products and participate in the world of manufacturing.

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 every Harvey and Helical tool 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

On the Autodesk HSM Tools page, you will find Harvey Tool and Helical Solutions tool libraries. Clicking either of the previous links will bring you to that brand’s tool libraries. Right now, all of the two brands more than 27,000 tools are supported in the tool libraries.

Once on the page, there will be a download option for both Fusion and HSM. Select which software you are currently using to be prompted with a download for the correct file format.

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

Speeds and Feeds

To ensure the best possible machining results, we have decided not to pre-populate speeds and feeds information into our tool libraries. Instead, we encourage machinists to access the speeds and feeds resources that we offer to dial accurate running parameters based on their material, application, and machine capabilities.

Harvey Tool Speeds & Feeds

To access speeds and feeds information for your Harvey Tool product, head to http://www.harveytool.com/cms/SpeedsFeeds_228.aspx to find speeds and feeds libraries for every tool.

If you are looking for tool specific speeds and feeds information, you will need to access the tool’s “Tech Info” page. You can reach these pages by clicking any of the hyperlinked tool numbers across all of our product tables. From there, simply click “Speeds & Feeds” to access the speeds and feeds PDF for that specific tool.

Tips for Maintaining Tight Tolerances

In manufacturing large production runs, one of the biggest difficulties machinists experience is holding tooling to necessary tolerances in holes, walls, and threads. Typically, this is an iterative process that can be tedious and stressful, especially for inexperienced machinists. While each job presents a unique set of challenges, there are rules of thumb that can be followed to ensure that your part is living up to its accuracy demands.

What is a Tolerance?

A tolerance is an allowable amount of variation in a part or cutting tool that a dimension can fall within. When creating a part print, tolerances of tooling can’t be overlooked, as tooling tolerances can result in part variations. Part tolerances have to be the same, if not larger, than tool tolerances to ensure part accuracy.

Cutting tool tolerances are oftentimes applied to a tool’s most critical dimensions, such as Cutter Diameter, Length of Cut, Shank Diameter, and Overall Length. When selecting a cutting tool for a job, it’s critical to choose a brand that adheres to strict tolerance standards and reliable batch-to-batch consistency. Manufacturers like Harvey Tool and Helical Solutions prominently display tolerances for many critical tool dimensions and thoroughly inspect each tool to ensure that it meets the tolerances specified. Below is the table header for Harvey Tool’s line of Miniature End Mills – Square – Stub & Standard.

tolerances

Tolerances help to create repeatability and specificity, especially in an industry in which even a thousandth of an inch can make or break a final product. This is especially true for miniature tooling, where Harvey Tool is experienced in the designing and manufacturing of tooling as small as .001” in diameter.

How are Tolerances Used?

When viewing a tolerance, there’s an upper and lower dimension, meaning the range in which the dimension of the tool can stray – both above and below what its size is said to be. In the below example, a .030″ cutter diameter tool’s size range would be anywhere between .0295″ and .0305.”

tooling tolerance

Maintaining Tolerances in Holemaking Operations

Holes oftentimes mandate the tightest dimensional tolerances, as they generally are meant to align perfectly with a mating part. To maintain tolerances, start first by testing the runout of both your machine and your tool. This simple, yet often overlooked step can save machinists a great amount of time and frustration.

Spotting Drills

Spotting Drills allow for drills to have a very precise starting point, minimizing walking or straying from a desired path. This can be especially beneficial when machining irregular surfaces, where accessing a hole’s perfect location can be more difficult.

spotting drills

Reamers

Reaming is great for any very tight tolerance mandate, because many Miniature Reamers have much tighter tolerances than a drill. Harvey Tool’s Miniature Reamers, for example, have tolerances of +.0000″/-.0002. for uncoated options and +.0002″/-.0000″ for AlTiN coated tools. Reamers cut on their chamfered edge, removing a minimal amount of material within a hole with the ultimate goal of bringing it to size. Because the cutting edge of a reamer is so small, the tool has a larger core diameter and is thus a more rigid tool.

miniature reamers

Maintaining Tight Tolerances While Machining Walls

Be Wary of Deflection

Maintaining tolerances when machining walls is made difficult by deflection, or the curvature a tool experiences when a force is applied to it. Where an angle is appearing on a wall due to deflection, opt for a reached tool to allow for less deflection along the tool’s neck. Further, take more axial depths of cut and machine in steps with finishing passes to exert less pressure on the tool. For surface finish tolerances, a long fluted tool may be required to minimize evidence of a tool path left on a part. For more information on ways to minimize deflection, read Tool Deflection & Its Remedies.tool deflection

Corner Radius End Mills

Corner radius End Mills, because they do not feature a sharp edge, will wear slower than a square end mill would. By utilizing corner radius tooling, fracturing on the tool edge will be minimized, resulting in an even pressure distribution on each of the cutting edges. Because the sharper edge on a square tool is less durable and more prone to cracking because of the stress concentration on that point, a corner radius tool would be much more rigid and thus less susceptible to causing a tolerance variation. For this reason, it’s recommended to use a roughing tool with a corner radius profile and a finisher with a square profile for an edge tolerance. When designing a part and keeping manufacturing in mind, if there is a potential for a wall with a radius as opposed to a wall with a square edge, a wall with a radius allows for easier machineability and fewer tool changes.

Maintaining Tight Tolerances While Threading

Making threads to tolerance is all about chip evacuation. Evacuating chips is an issue commonly overlooked; If chips within a hole have not been removed before a threading operation, there could be interference in the tool tip that leads to vibration and chatter within a thread. This would decrease the continuity of the thread while also altering the points of contact. Discontinuity of a thread could be the difference between passing and failing a part, and because threading is typically the last application when machining to decrease damaging the threads, it also increases the likelihood of chips remaining within the hole from other applications.

Tolerances Summarized

If you continue to experience troubles maintaining tight tolerances despite this blog post, consult the Harvey Tool or Helical Solutions tech team, as the problem may exist outside of your machine. Temperature and humidity can vary how gummy a material is, and can lead to workpiece expansion and contraction. Additionally, the foundation of buildings can expand and contract due to outside temperature, which can result in upped runout and irregular vibration in a spindle.
