Parameter Description
The positions refer to the reference point:
X0 Reference point X – (only for single position)
Y0 Reference point Y – (only for single position)
Z0 Reference point Z – (only for single position)
(only for G code)
Face C: The positions refer to the reference point:
X0 or L0 Reference point X or reference point length polar – (only for single position)
Y0 or C0 Reference point Y or reference point angle polar – (only for single position)
Z0 Reference point Z – (only for single position)
(only for Shop‐
Turn)
Face Y: The positions refer to the reference point:
CP Positioning angle for machining area – (only single position)
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.
X0 or L0 Reference point X or reference point length polar – (only for single position)
Y0 or C0 Reference point Y or reference point angle polar - (only for single position)
Reference point Z - (only for single position)
Z0
(only for Shop‐
Turn)
Peripheral surface C: The positions refer to the reference point:
Y0 or C0 Reference point Y or reference point angle polar - (only for single position)
Z0 Reference point Z - (only for single position)
X0 Cylinder diameter ∅ – (only for single position)
(only for Shop‐
Turn)
Peripheral surface Y: The positions refer to the reference point:
C0 Positioning angle for machining surface – (only for single position)
Y0 Reference point Y – (only for single position)
Z0 Reference point Z – (only for single position)
X0 Reference point X – (only for single position)
(only for Shop‐
Turn)
