Parameter Description
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)
Z0 Reference point Z – (only for single position)
(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)
W Width of spigot
L Length of spigot
R Corner radius
α0 Angle of rotation
Z1 Spigot depth (abs) or depth relative to Z0 or X0 (inc) - (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 ∇∇∇)
W1 Width of blank spigot (important for determining approach position) - (only for ∇ and
∇∇∇)
L1 Length of blank spigot (important for determining approach position) - (only for ∇ and
∇∇∇)
FS Chamfer width for chamfering - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only)
* Unit of feedrate as programmed before the cycle call
