Machining Operations
Global data valid everywhere
 Set-up clearance: Distance between tool tip and workpiece surface
for automated approach of the cycle start position in the tool axis.
 2nd setup 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.
 F positioning: Feed rate at which smarT.NC traverses the tool within
a cycle.
 F retraction: Feed rate with at smarT.NC retracts the tool.
Global data for positioning behavior
 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 working unit.
