F Feedrate
Parameter Description
FZ Depth infeed rate (only for ∇ and ∇∇∇)
(only for ShopMill)
FZ Depth infeed rate (only for ∇ and ∇∇∇)
(only for G code)
Machining
∇ (roughing)
•
∇∇∇ (finishing)
•
∇∇∇ edge (edge finishing)
•
Chamfering
•
Circular pattern
Full circle
•
The circumferential grooves are positioned around a full circle. The groove spacing
is uniform and is calculated by the controller.
Pitch circle
•
The circumferential grooves are positioned around a pitch circle. The groove
spacing can be determined on the basis of angle α2.
The positions refer to the center point:
X0 Reference point X
Y0 Reference point Y
Z0 Reference point Z
N Number of grooves
R Radius of circumferential groove
α0 Starting angle
α1 Opening angle of the groove
α2 Advance angle - (for pitch circle only)
W Slot width
Z1 Slot depth (abs) or depth relative to Z0 (inc) – (only for ∇, ∇∇∇ and
∇∇∇ edge)
DZ Maximum depth infeed - (only for ∇, ∇∇∇ and ∇∇∇ Rand)
