Parameter Description
The positions refer to the center point:
X0 Reference point X
Y0 Reference point Y
Z0 Reference point Z
N Number of edges
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 in relation to Z0 (inc) - (only for ∇, ∇∇∇ and ∇∇∇ edge)
DZ Maximum depth infeed – (only for ∇ and ∇∇∇ edge)
FS Chamfer width for chamfering - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only)
UXY Plane finishing allowance - (only for ∇, ∇∇∇ and ∇∇∇ edge)
Positioning Positioning motion between the slots:
● Straight line:
● Circular:
* Unit of feedrate as programmed before the cycle call
