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 to
which the tool is retracted, is selected as follows:
● To retraction plane
● Z0 + safety clearance
If there are no elements larger than Z0 in the pocket area, "Z0 + safety clearance" can
be selected as the lift mode.
