Programming technology functions (cycles)
10.4 Milling
Parameter Description
Machining ● ∇ (roughing)
● ∇∇∇ (finishing)
● ∇∇∇ edge (edge finishing)
● Chamfering
Machining ● Single position
position
A multiple edge is milled at the programmed position (X0, Y0, Z0).
● Position pattern
Several multiple edges are milled at the programmed position pattern (e.g. pitch
(only for G code)
circle, grid, line).
The positions refer to the reference point:
X0 (only G code) Reference point X – (only for single position)
Y0 (only G code) Reference point Y – (only for single position)
Z0 Reference point Z – (only for single position)
∅ 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)
