Parameter Description
Machining The following machining operations can be selected:
∇ (roughing)
TR Reference tool Tool, which is used in the "Stock removal" machining step. Is used to
determine the residual material.
D Cutting edge number
Z0 Reference point in the tool axis Z
Z1 Pocket depth (abs) or depth referred to Z0 (inc)
DXY
Maximum plane infeed
•
Maximum plane infeed as a percentage of the milling cutter diameter
•
DZ Maximum depth infeed
UXY Finishing allowance, plane
UZ Finishing allowance, depth
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.
