Parameter Description Unit
TR Reference tool Tool, which is used in the "solid machining" machining step. This is
used to determine the plunge position.
Z0 Reference point Z mm

UXY Finishing allowance, plane mm
UZ Finishing allowance, depth mm
Lift mode
Lift mode before new infeed
If the machining operation requires several points of insertion, the retraction height can
be programmed:
To retraction plane
Z0 + safety clearance
When making the transition to the next insertion point, the tool returns to this height. If
there are no elements larger than Z0 in the pocket area, "Z0 + safety clearance" can be
selected as the lift mode.
