illing in C axis
"ICP drilling, C axis" unit
The unit machines a single hole or a hole pattern on the face or lateral
surface. Using ICP, you define the holes as well as further details.
Unit name: G74_ICP_C / Cycle: G74 (see page 319)

 0: Rapid traverse
 1: Feed rate
V Feed rate reduction
 0: Without reduction
 1: At end of the hole
 2: At start of the hole
 3: At start and end of the hole
AB Spot drilling / through drilling length (distance for feed rate
reduction)
P Hole depth
IB Hole depth reduction value: Value by which the feed depth
decreases after every advance.
JB Minimum hole depth: If you have entered a hole depth
reduction value, the hole depth is reduced only to the value
entered in JB.
B Retraction distance: Value by which the tool is retracted
after reaching the respective hole depth.
RI Internal safety clearance: Distance for reapproach inside
the hole (default: safety clearance SCK).
RB Return plane (default: return to the starting position or to
the safety clearance)
