Parameter Description
Reference point Position of the reference point:
(lefthand edge)
•
(inside left)
•
(center)
•
(inside right)
•
(righthand edge)
•
Machining
∇ (roughing)
•
∇∇∇ (finishing)
•
∇∇∇ edge (edge finishing)
•
Chamfering
•
Machining
Single position
•
position
A slot is milled at the programmed position (X0, Y0, Z0).
Position pattern
•
Several slots are milled at the programmed position pattern (e.g. pitch circle, grid,
line).
The positions refer to the reference point:
X0 Reference point X – (for single position only)
Y0 Reference point Y – (for single position only)
Z0 Reference point Z – (only for single position and G Code position pattern)
W Slot width
L Slot length
α0 Angle of rotation
Z1 Slot depth (abs) or depth relative to Z0 (inc) – (only for ∇, ∇∇∇ and ∇∇∇ edge)
DXY (only
Maximum plane infeed
•
ShopMill)
Maximum plane infeed as a percentage of the milling cutter diameter
•
- (only for ∇ and ∇∇∇)
DZ Maximum depth infeed - (only for ∇, ∇∇∇ and ∇∇∇ Rand)
UXY Plane finishing allowance - (only for ∇, ∇∇∇ and ∇∇∇ edge)
UZ Depth finishing allowance (slot base) - (only for ∇ and ∇∇∇)
