Peripheral surface C

Peripheral surface Y

Clamp/release spindle (only for end face Y/B and peripheral surface Y)
The function must be set up by the machine manufacturer.
(only for
ShopTurn)
Z0 Reference point in the tool axis Z
Z1 Pocket depth (abs) or depth referred to Z0 or X0 (inc)
CP Positioning angle for machining area
- (only for ShopTurn, machining surface, face Y)
C0 Positioning angle for machining surface
- (only for ShopTurn, machining surface, peripheral surface Y)
DXY
Maximum plane infeed

Maximum plane infeed as a percentage of the milling cutter diameter

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 can
be programmed:
To retraction plane

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.
