Cycle run:
1 Cutter moves at rapid traverse to the starting point
RB not programmed: moves up to the safety clearance
RB programmed: moves to the position RB and then to the
safety clearance
2 The tool mills in a helix from the current position to the first
plunging depth at the programmed feed rate
3 When the drilling depth has been reached, the tool moves along
helical paths to the outside until it reaches the programmed hole
diameter
4 Finally, the tool moves by a full circle to remove the material left.
5 Repeats 2 to 3 if the maximum infeed P does not correspond to
the drilling depth
6 Retraction position:
RB not programmed: retraction to the starting point
RB programmed: retraction to the position RB
