1186 Manufacturing is a high-production machine shop focused mainly on making large parts for the Aerospace industry. The company was founded by Devon Dupuis, a self-taught machinist who has quickly distanced himself from the competition by adopting the newest machining technologies in his shop. Devon was kind enough to take some time out of his busy schedule to talk with us about his thoughts on 5 axis machining, maintaining a competitive edge over his competition, and the impact that Harvey Tool and Helical Solutions cutting tools have had on his shop’s performance.
Tell us a little bit about 1186 Manufacturing and how you got started in this industry.
I actually started in manufacturing by programming manual machines like Bridgeports while working in a shop that manufactured suspensions. I ended up learning CNC programming indirectly after working on a couple of programs and just being exposed to it. I have no “formal” training in CNC machining or programming; everything I learned was from my hands-on experiences on the shop floor.
I started 1186 Manufacturing in my garage with a Haas Mini-Mill. I was making rings, small firearm accessories, and everyday-carry items like wallets and other small items. After pushing that machine to the limits for a couple of years, I took the leap and decided to expand the business.
Pretty quickly we saw one machine turn into four, and we eventually made the switch to the larger DMG Mori machines to be able to manufacture some of the massive parts which the Aerospace industry was starting to send our way. Now, manufacturing parts for the Aerospace industry has become the core of our business, and our machines keep getting bigger. At this point, a lot of quotes come down to simply having a big enough machine to make what these Aerospace companies need. By going big, we have been able to earn a lot of their business over our competition.
What sort of machines do you use in your shop?
We actually started with a few Haas machines in our earlier days – a UMC-750SS, a VF-6SS, and a VF-3SSYT. When we made the switch to larger machines, we went with the 5 axis DMG Mori machines and we now have four of those; a DMF 260-11, a DMU 125, a 60 eVo Linear, and a DMC 85 with a pallet changer. We are hoping to add another 5 axis machine, the DMG 340 Gantry, sometime in the near future.
Recently, we had John Saunders from NYC CNC stop in the shop and do a quick tour, so you can see most of our machines up-close and personal in that video (below).
That is some serious 5 axis power. What advice would you have for others when it comes to 5 axis machining?
I think that people need to adapt to new technology to stay ahead of their competition. I have been in shops where people are doing 10-15 setups for a single part, and it just wastes so much valuable time. That same part could be done in 2 operations on a 5 axis mill. When you really think about the lost time and the amount of scrapped parts due to the constant moving and misloading during setups, you could have paid for a 5 axis machine with the money you lost.
Right now, with software like AutoDesk Fusion 360, it is easier than ever to learn to program a 5 axis machine. A lot of the basic machining principles remain the same; some people are looking at this and making it more difficult than it needs to be. If you can program and run a 3 axis machine, taking the next step to 3+2 and eventually 5 axis machining is not as hard as it may sound.
Do you have a favorite material to machine? What material has been the most difficult for you?
We work with a lot of Aluminum. About 90% of our parts are in Aluminum, and it just cuts like butter, so that is by far my favorite material to machine. We machine so much Aluminum that we regularly go through a 14 cubic yard hopper full of chips in just a week. We are making parts faster than we can even get the chips out the door for recycling.
Recently, we have been getting more Stainless Steel jobs, and the A286 alloy has been an extremely difficult material to work with. We love a challenge, but it is definitely my least favorite material to machine.
How did you first hear about Harvey Tool and Helical Solutions?
I first heard about Harvey Tool and started using their products about 9-10 years ago. I was making much smaller parts then, and would use a lot of the Harvey Tool miniature end mills and some of the specialty profiles for specific cuts.
Nowadays, we are making much larger parts, so we don’t get to use the Harvey Tool products as often. When we started moving into our new space, one of our customers saw us cutting stainless steel and mentioned Helical. I searched a few videos online, and saw a crazy test run of a Helical end mill running at something like 10k RPMs in stainless. We had only been running at 800-900 RPMs with our current tooling, so we knew we had to try these tools right away.
How have the tools impacted your business?
We now use Helical tools for everything because we can push them harder than any other brand. We have performed many head to head tests and haven’t found anything that can compete at the same speeds as the Helical end mills. Carrying reduced neck end mills as a standard stocked item is also huge for us with the 5 axis work we do. We used to have to buy end mills and grind them down ourselves to get that reduced neck, but we are able to save valuable time by just ordering them standard with our other tools from Helical.
In Aluminum, most tools cut like butter, but the Helical ones have always been able to run faster with better tool life. As we have started moving into more Stainless/Hardened Steels, Helical has pulled through for us every time. Previously, we could go through a $50 tool from another brand in just one part. Now, we can get four parts out of the Helical tool, while pushing even faster than before. For high-production shops like ours, speed and cost is everything, and Helical tools have constantly outperformed the competition.
You were an early adopter of Machining Advisor Pro – how have your experiences been with the software and parameters it is outputting?
We were actually an early adopter of the original Helical Milling Advisor after we had it recommended to us by another customer, and so we signed up for Machining Advisor Pro as soon as it became available. It makes sense that it became a web-based software; now we can get updated with the latest tooling information and formulas without needing to download a new version on all of our computers.
So far, we have been very happy with it. We constantly recommend it to others. A lot of what I do for speeds and feeds can come right off the top of my head and with some tweaks I can figure it out, but having software like Machining Advisor Pro allows us to double check our speeds and feeds and figure out how we can push the tools even faster. The biggest thing is that it always gets our guys close. No matter what their level of experience is, they can plug the information into MAP and get some great starting parameters that are always on point.
What is your key to staying ahead of the competition and winning quotes?
In manufacturing, you not only have to worry about competing with your neighbor but also competing with shops overseas that can offer low-cost quotes. However, we have found that by pushing our machines as quickly as we can and using 5 axis machining to improve our cycle times, we can offer extremely competitive quotes with a faster turnaround. Some of our machines are pushing so hard and fast that it is difficult to keep enough workpieces in front of them at times.
My favorite thing to tell customers when they ask how long the lead time will be on a part is that it will take longer to get the material in the shop than it will to make the parts. We can make parts at such an outstanding rate here because of our investment in technology. This is truly what sets us apart from everyone else.
What advice do you have for the In The Loupe community?
Embrace technology, embrace multi-axis machining, and keep pushing your limits. Losing less time to setups and moving operations like deburring into our machines has saved us so much time and money while increasing our production rates to new highs. If you are not taking a hard look at adopting some of the new advances in machining technology, then you are already behind your competition.
