Explanation:
In this example, a full circle with a radius of 70 mm is machined in the X/Y plane. Since the tool has a radius of 10
mm, the resulting tool center point path describes a circle with a radius of 60 mm. The start/end points are at X0
Y0 Z60, with the result that a movement takes place in the Z direction at the same time as the approach/
retraction movement in the compensation plane.

plane.
