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