Additional parameters on the drilling parameters detail form:
8 Chip breaking depth: Depth at which smarT.NC carries out chip
breaking.
8 Decrement: Value by which smarT.NC decreases the plunging depth.
8 Min. infeed: If a decrement has been entered: Limit for minimum
infeed.
8 Upper adv.stop dist.: Upper set-up clearance for repositioning after
chip breaking.
8 Lower adv.stop dist.: Lower set-up clearance for repositioning after
chip breaking.
8 Infeed start point: Lower starting point relative to the surface
coordinates for pre-machined holes
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 Dwell time at depth
8 Feed rate for traversing between machining positions
