Parameter Description
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 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)
W Width of spigot
L Length of spigot
R Corner radius
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 ∇∇∇)
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 and inc) - (for chamfering only)
* Unit of feedrate as programmed before the cycle call
Hidden parameters
The following parameters are hidden. They are pre-assigned fixed values or values that can
be adjusted using setting data.
