Parameter Description
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)
N Number of slots
R Radius of circumferential slot
α0 Starting angle
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 ∇, ∇∇∇)
DZ Maximum depth infeed - (only for ∇, ∇∇∇ )
UXY Plane finishing allowance – (only for ∇, ∇∇∇)
Positioning Positioning motion between the slots:
● Straight line:
Next position is approached linearly in rapid traverse.
● Circular:
Next position is approached along a circular path at the feedrate
defined in a machine data code.
FS Chamfer width for chamfering (inc) - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only)
