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.
