Global data valid everywhere
U Set-up clearance : Distance between tool tip and workpiece surface
for automated approach of the cycle start position in the tool axis
U 2nd set-up clearance: Position to which smarT.NC positions the tool
at the end of a machining step. The next machining position is
approached at this height in the machining plane
U F positioning : Feed rate at which smarT.NC traverses the tool within
a cycle
U F retraction : Feed rate at which smarT.NC retracts the tool
Global data for positioning behavior
U Positioning behavior : Retraction in the tool axis at the end of the
machining step: Return to the 2nd set-up clearance or to the position
at the beginning of the unit
