Parameter Description
Machining The following machining technologies can be selected:
● ∇ (roughing)
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)
TR Reference tool Tool, which is used in the "stock removal" machining step. This is used
to determine the residual corners.
D Cutting edge number
Z0 Reference point in tool axes Z
Pocket depth (abs) or depth referred to Z0
Z1
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
DZ Maximum depth infeed
