Parameter Description Unit
Machining The following machining operations can be selected:
∇ (roughing)
TR Reference tool Tool, which is used in the "solid machining" machining step. This is
used to determine the residual corners.
D Cutting edge number
Z0 Reference point mm
Z1 Pocket depth (abs) or depth referred to Z0 (inc) mm
DXY 
Maximum plane infeed

Maximum plane infeed as a percentage of the milling cutter diameter
mm
%
DZ Maximum depth infeed 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 RP

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.
