10.4 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
● Conventional
● Climbing-conventional milling
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 – (only for single position)
Y0 Reference point Y – (only for single position)
Z0 Reference point Z – (only for single position)
(only for G code)
Face C: The positions refer to the reference point:
X0 or L0 Reference point X or reference point length polar – (only for single position)
Y0 or C0 Reference point Y or reference point angle polar – (only for single position)
Z0 Reference point Z – (only for single position)
(only for Shop‐
Turn)
Face Y: The positions refer to the reference point:
CP Positioning angle for machining area – (only single position)
Angle CP does not have any effect on the machining position in relation to the workpiece.
It is only used to position the workpiece with the rotary axis C in such a way that machining
is possible on the machine.
X0 or L0 Reference point X or reference point length polar – (only for single position)
Y0 or C0 Reference point Y or reference point angle polar - (only for single position)
Z0 Reference point Z - (only for single position)
(only for Shop‐
Turn)
Peripheral surface C: The positions refer to the reference point:
Y0 or C0 Reference point Y or reference point angle polar - (only for single position)
Z0 Reference point Z - (only for single position)
X0 Cylinder diameter ∅ – (only for single position)
(only for Shop‐
Turn)
