Finishing external circular ramping
Compared to internal circular milling/ramping: The tool centre feed, vf, is increased instead of reduced. The radial depth, ae, becomes much smaller when milling externally, therefore, a higher cutting speed can be used. hex is calculated in the same way as for edging. The programming technique is otherwise very similar to internal milling of holes.
CoroMill®790 with GC1010 with high ramping capability generates straight shoulders with minimal mismatch and very low cusps when passes are repeated.
