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 Reference point Z
(only for ShopTurn)
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 Cylinder diameter ∅
(only for ShopTurn)
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)
N Number of slots
R Radius of circumferential slot
α1 Opening angle of the slot
α2 Advance angle - (for pitch circle only)
W Slot width
Z1 Slot depth (abs) or depth relative to Z0 or X0 (inc) - (only for ∇ and ∇∇∇)
DZ Maximum depth infeed – (only for ∇ and ∇∇∇)
UXY Plane finishing allowance – (only for ∇ and ∇∇∇)
Positioning Positioning motion between the slots:
● Straight line:
● Circular:
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
540
Next position is approached linearly in rapid traverse.
Next position is approached along a circular path at the feedrate defined in the
machine data.
