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
ShopTurn)
Face Y: The positions refer to the reference point:
CP Positioning angle for machining area – (only single position)
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
ShopTurn)
