CUTTING TOOLS
Advanced Tooling Solutions Trump Material Challenges According to Michael Standridge, aerospace industry specialist at Sandvik
Coromant (Fair Lawn, NJ), aerospace manufacturers are faced with critical issues affecting capacity, cycle time, cutter security, tool life, repeatability, longevity, and part quality. “There’s a lot of pressure on the supply chain to deliver quality parts on time to meet increasing monthly production rates for commercial aircraft. With the strong forecast and large volumes of aircraft to produce over the next 25 years we are seeing an increase in the quantity of all major component groups within the engine, frame structures, and landing gear,” said Standridge. “At our Aerospace Application Center, we offer many solutions for our custom-
ers: from machining strategy and process development on a particular material or component feature, to cutting tool application and design, as well as full turnkey services that includes CAM programming. CAM programs are complete and verifi ed. The real benefi ts of our center comes from having the ability to show our customers the latest techniques that demonstrate how to get the most productivity out of our cutting tools, plus it gives us the ability to develop solutions outside of their facility, which can then integrate into their facility,” said Standridge.

“Titanium, particularly 6AL4V titanium, has been used in aircraft for a long time and the industry has a pretty good handle on machining it. What we’re looking for are ways to machine it faster with reliability and a cost-effective process. To do this we are investigating advanced manufacturing methods, for example, the use of cryogenic coolant to help increase tool life and cutting speed, as well as the use of laser technology softening the titanium material prior to cutting. The industry is always seeking new materials to aid the design of aircraft. Beta 21 titanium is something we are starting to see more and more of particularly in smaller compo- nents. Beta 21 is not diffi cult to cut, but challenging because it’s very sensitive to cutting forces and vibration. Another Beta titanium, 5553 titanium, which was a
