Parameter Description
Machining
Single position
•
position
A polygon is milled at the programmed position (X0, Y0, Z0).
Position pattern
•
Several polygons 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 – (single position only and G Code position pattern)
∅ Diameter of blank spigot
N Number of edges
SW or L Width across flats or edge length
α0 Angle of rotation
R1 or FS1 Rounding radius or chamfer width
Z1 Multi-edge depth (abs) or depth in relation to Z0 (inc) - (only for ∇, ∇∇∇ and ∇∇∇ edge)
DXY
Maximum plane infeed
•
Maximum plane infeed as a percentage of the milling cutter diameter
•
- (only for ∇ and ∇∇∇)
DZ Maximum depth infeed - (only for ∇ and ∇∇∇)
UXY Plane finishing allowance - (only for ∇, ∇∇∇ and ∇∇∇ edge)
UZ Depth finishing allowance – (only for ∇ and ∇∇∇)
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
