8.2 Milling
Parameter Description
Technology
Vortex milling
•
The milling cutter performs circular motions along the length of the slot and back
again.
Plunge cutting
•
Sequential drilling motion along the tool axis.
Milling direction: - (except plunge cutting).
Climbing cutting
•
Conventional cutting
•
Climbing-conventional cutting
•
Machining
Single position
•
position
Mill a slot at the programmed position (X0, Y0, Z0).
Position pattern
•
Mill slots at a programmed position pattern (e.g. full circle or grid).
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 of slot
Z1 Slot depth (abs) or depth relative to Z0 (abs) – (only for ∇, ∇∇∇, ∇∇∇ base and ∇∇∇
rough finishing)
DXY
Maximum plane infeed
•
Maximum plane infeed as a percentage of the milling cutter diameter
•
- (only for ∇)
DZ Maximum depth infeed - (only for ∇, ∇∇∇ rough finishing, ∇∇∇ and ∇∇∇ edge)
- (only for vortex milling)
UXY Plane finishing allowance (slot edge) - (only for ∇, ∇∇∇ rough finishing and ∇∇∇ base)
UZ Depth finishing allowance (slot base) - (only for ∇, ∇∇∇ rough finishing and ∇∇∇ edge )
FS Chamfer width for chamfering (inc) - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only)
* Unit of feedrate as programmed before the cycle call
