Global data for milling operations with contour cycles
U Setup clearance : Distance between tool tip and workpiece surface for
automated approach of the cycle start position in the tool axis
U Clearance height : Absolute height at which the tool cannot collide
with the workpiece (for intermediate positioning and retraction at the
end of the cycle)
U Overlap factor : The tool radius multiplied by the overlap factor equals
the lateral stepover
U Climb or up-cut : Select the type of milling
Global data for probing functions
U Setup clearance : Distance between stylus and workpiece surface for
automated approach of the probing position
U Clearance height : The coordinate in the touch probe axis to which
smarT.NC traverses the touch probe between measuring points if the
Move to clearance height
option is activated
U Move to clearance height : Select whether smarT.NC moves the touch
probe to the setup clearance or clearance height between the
measuring points
