Milling a chamfer on a contour

This NC program is for multipass-milling a chamfer on the upper edge of any contour. The control first machines the contour with Cycle 25. It then mills the chamfer in contour lines. Milling of the contour can be performed with an end mill, a ball-nose cutter, or a toroid cutter. For this purpose, the control reads the radius of the cutting edge from the tool table and calculates the corresponding tool path, without you needing to change anything in the NC program.
