HEIDENHAIN ITNC 530 - PILOT SMART NC Manual page 76

Additional parameters on the drilling parameters detail form:
U
Chip breaking depth: Depth at which chip breaking is to occur
U Angle of spindle: Angle to which smarT.NC positions the tool before
thread cutting: This permits regrooving of the thread, if needed
U S factor for retraction Q403: Factor by which the TNC increases
the spindle speed — and therefore also the retraction feed rate —
when retracting from the hole
Globally effective parameters on the global data detail form:
U Setup clearance
U 2nd setup clearance
U
Retraction value for chip breaking
U Feed rate for traversing between machining positions
