Subprograms: Overlapping pockets
The pocket elements A and B overlap.
The control automatically calculates the points of intersection S1 and S2,
so these points do not have to be programmed.
The pockets are programmed as full circles.

Depending on the control setup (machine parameters), machining starts
either with the outline or the surface:
