Parameter Description
Machining
● Face C
surface
● Face Y
(only for Shop‐
● Face B
Turn)
● 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 Shop‐
Turn)
Machining The following machining operations can be selected:
● ∇ (roughing)
● ∇∇∇ base (base finishing)
● ∇∇∇ edge (edge finishing)
● Chamfering
Z0 Reference point in 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)
Angle CP does not have any effect on the machining position in relation to the workpiece.
It is only used to position the workpiece with the rotary axis C in such a way that machining
is possible on the machine.
C0 Positioning angle for machining surface
- (only for ShopTurn, machining surface, peripheral surface Y)
● Maximum plane infeed
DXY
● Maximum plane infeed as a percentage of the milling cutter diameter
- (only for ∇ and ∇∇∇ base)
DZ Maximum depth infeed
– (only for ∇ or ∇∇∇ edge)
UXY Finishing allowance, plane
– (only for ∇, ∇∇∇ base or ∇∇∇ edge)
UZ Finishing allowance, depth
– (only for ∇ or ∇∇∇ base)
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.
FS Chamfer width for chamfering - (only for chamfering machining)
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering machining only)
