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