Explanations

After reaching the programmed depth of cut for each cutting feed Q, retraction to

reference level R is performed in rapid traverse. Approach movement for a rene-

wed cut is again carried out in rapid traverse up to a distance (d) which is set to

GUD7 _ZSFR[1]. Distance d and the depth of cut for each cutting feed Q are tra-

versed with cutting feed. Specify Q incrementally implemented without sign.

Axis switching

The canned cycle must be canceled before the drilling axis can be changed.
