Parameter Description Unit
Machining
The following machining operations can be selected:
 ∇ (roughing)
 ∇∇∇ base (base finishing)
 ∇∇∇ edge (edge finishing)
 Chamfering
Z0 Reference point Z mm
Z1 Pocket depth (abs) or depth relative to Z0 (inc)
- (only for ∇, ∇∇∇ base or ∇∇∇ edge)
mm
DXY
 Maximum plane infeed
 Maximum plane infeed as a percentage of the milling cutter diameter
- (only for ∇ and ∇∇∇ base)
mm
%
DZ Maximum depth infeed – (only for ∇ or ∇∇∇ edge) mm
UXY Plane finishing allowance – (only for ∇, ∇∇∇ base or ∇∇∇ edge) mm
UZ Depth finishing allowance – (only for ∇ or ∇∇∇ base) 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 (X0) in the pocket area, then Z0 (X0) + safety
clearance can be programmed as the lift mode.
