Additional parameters on the drilling parameters detail form:
8 Chip breaking depth: Depth at which chip breaking is to occur.
8 Angle of spindle: Angle to which smarT.NC positions the tool before
thread cutting: This permits regrooving of the thread, if needed.
8 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 drill hole.
Globally effective parameters on the global data detail form:
8 Set-up clearance
8 2nd set-up clearance
8 Retraction value for chip breaking
8 Feed rate for traversing between machining positions
