Mastercam’s applications engineers scaled down an aerospace wing rib section to test the limits of Dynamic Motion technology.
After running the recommended speeds and feeds (20% step over and full depth of cut), they pushed the envelope and ended up with a 70% step over, with tool and machine showing no signs of wear or slowing down.
The only limitation they found was the inability to clear the chips out of the machine fast enough! For the production run, Dynamic Motion decreased cycle times over 50%, increased tool life, and reduced the machine load. With Dynamic Motion, the sky is the limit.
