Parameter Description
Machining The following machining operations can be selected:
● ∇ (roughing)
● ∇∇∇ (finishing)
● ∇∇∇ edge (edge finishing)
● Chamfering
Machining
● Face C
surface (only for
● Face Y
ShopTurn)
● Peripheral surface C
● Peripheral surface Y
Position (only for
● At the front (face)
ShopTurn)
● At the rear (face)
● Outside (peripheral surface)
● Inside (peripheral surface)
Clamp/release spindle (only for end face Y/peripheral surface Y)
The function must be set up by the machine manufacturer.
(only for ShopTurn)
The positions refer to the reference point:
X0 Reference point X
Y0 Reference point Y
Z0 Reference point Z
(only for G code)
Face C: The positions refer to the reference point:
X0 or L0 Reference point X or reference point length polar
Y0 or C0 Reference point Y or reference point angle polar
Z0 (only for Shop‐ Reference point Z
Turn)
Face Y: The positions refer to the reference point:
CP Positioning angle for machining area
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 ma‐
chining is possible on the machine.
X0 or L0 Reference point X or reference point length polar
Y0 or C0 Reference point Y or reference point angle polar
Z0 (only for Shop‐ Reference point Z
