Cycle "high-speed deep hole drilling":
Mα: M function for locking the C axis
M(α+1): M function for releasing the C axis
P1: Dwell time (Program)
P2: Specification of the dwell time in USER DATA, _ZSFR[22]
d: Specification of the retraction amount in USER DATA, _ZSFR[21]
Deep hole drilling cycle (G83, G87) (USER DATA, _ZSFI[20]=1)
In case of the deep hole drilling cycle, the drill repeats the infeed with the cutting feedrate. This is retracted to the plane R till
the tool has reached the bottom of a hole.
