Global data for milling operations with contour
cycles
 Set-up clearance: Distance between tool tip and workpiece
surface for automated approach of the cycle start position in the tool
axis.
 Clearance height: Absolute height at which the tool cannot collide
with the workpiece (for intermediate positioning and retraction at
the end of the cycle).
 Overlap factor: The tool radius multiplied by the overlap factor
equals the lateral stepover.
 Climb or up-cut: Select the type of milling.
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.
Global data for probing functions
 Set-up clearance: Distance between stylus and workpiece surface
for automated approach of the probing position.
 Clearance height: The coordinate in the touch probe axis to which
the TNC traverses the touch probe between measuring points, if the
Move to clearance height
option is activated.
 Move to clearance height: Select whether the TNC moves the
touch probe to the set-up clearance or clearance height between the
measuring points.
The parameters apply to SL cycles 20, 22, 23, 24 and 25.
The parameters apply to each machining cycle that you call
with the CYCL CALL PAT function.
Applies to all touch-probe cycles 4xx.
