SysMillCircularPocket - Mill circular pocket

This cycle is used to mill a circular pocket.

In this cycle, the tool is fed incrementally along the Z axis and the pocket is also milled from the inside out along a circular or helical path plane-by-plane for each machining height. To mill the circular pocket, the tool is always lowered over the centre of the circular pocket. If the milling cutter does not cut above centre, the circular pocket can be predrilled in the centre before the cycle.
