Parameter Description
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
Turn)
Peripheral surface C: The positions refer to the reference point:
Y0 or C0 Reference point Y or reference point angle polar
Z0 Reference point Z
X0(only for Shop‐ Cylinder diameter ∅
Turn)
Peripheral surface Y: The positions refer to the reference point:
C0 Positioning angle for machining surface
Y0 Reference point Y
Z0 Reference point Z
X0 Reference point X
(only for ShopTurn)
∅1 Diameter of blank spigot (important for determining approach position) - (only for ∇ and
∇∇∇)
∅ Diameter of spigot
Z1 Depth relative to Z0 or X0 (inc) or spigot depth (abs) - (only for ∇ and ∇∇∇)
DZ Maximum depth infeed – (only for ∇ and ∇∇∇)
UXY Plane finishing allowance for the length (L) and width (W) of the rectangular spigot.
Smaller rectangular spigot dimensions are obtained by calling the cycle again and pro‐
gramming it with a lower finishing allowance.
- (only for ∇ and ∇∇∇)
UZ Depth finishing allowance (tool axis) - (only for ∇ and ∇∇∇)
FS Chamfer width for chamfering - (for chamfering only)
ZFS Insertion depth of tool tip (abs and inc) - (for chamfering only)
(ZFS for machining surface, face C/Y or XFS for peripheral surface C/Y)
