Milling a radius on a contour

This NC program is for multipass-milling a radius on the upper edge of a contour. At first, the control machines the contour with Cycle 25. Then it mills the radius in contour lines. The milling of the radius can be performed with an end mill, a ball-nose cutter, or a toroid cutter. For this purpose, the control reads the tool cutter radius from the tool table and calculates the corresponding tool paths, without you having to make any changes to the NC program.
