Global data for milling operations with pocket
cycles 25x
 Overlap factor
: The tool radius multiplied by the overlap factor
equals the lateral stepover
 Climb or up-cut
: Select the type of milling
 Plunging type
: Plunge into the material helically, in a reciprocating
motion, or vertically
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 unit
The parameters apply to milling cycles 251 to 257.
The parameters apply to SL cycles 20, 22, 23, 24 and 25.
The parameters apply to each fixed cycle that you call with
the CYCL CALL PAT function.
