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[10]. Distance d and the depth of cut for each cutting feed Q are tra-
versed with cutting feed. Specify Q incrementally implemented without sign.
Notice
If _ZSFR[10]
S > 0 = value is used for anticipation distance "d" (distance minimal 0.001)
S = 0 The anticipation distance d is calculated internally in the cycles as follows:
S If the drilling depth is 30 mm, the value of the anticipation distance is al-
ways 0,6 mm.
S For larger drilling depths, the formula drilling depth/50 is used (maximum
value 7 mm).
