Programming technology functions (cycles)
10.4 Milling
Parameter Description
Milling direction - (except plunge cutting)
● Climbing
● Conventional
● Climbing-conventional milling
The positions refer to the reference point:
X0 Reference point X
Y0 Reference point Y
Z0 Reference point Z
(only for G code)
Face C: The positions refer to the reference point:
X0 or L0 Reference point X or reference point length polar
Y0 or C0 Reference point Y or reference point angle polar
Z0 Reference point Z
(only for ShopTurn)
Face Y: The positions refer to the reference point:
CP Positioning angle for machining area
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 ma‐
chining is possible on the machine.
X0 or L0 Reference point X or reference point length polar
Y0 or C0 Reference point Y or reference point angle polar
Z0 Reference point Z
(only for ShopTurn)
Peripheral surface C: The positions refer to the reference point:
Y0 or C0 Reference point Y or reference point angle polar
Z0 Reference point Z
X0 Cylinder diameter ∅
(only for ShopTurn)
Peripheral surface Y: The positions refer to the reference point:
C0 Positioning angle for machining surface
Y0 Reference point Y
Z0 Reference point Z
X0 Reference point X
(only for ShopTurn)
W Slot width
L Slot length
Z1 Slot depth (abs) or depth relative to Z0 (abs) – (only for ∇, ∇∇, ∇∇∇ and ∇∇∇ base)
(only for G code)
Z1 or X1 Slot depth (abs) or depth relative to Z0 or X0 (abs) – (only for ∇, ∇∇, ∇∇∇, ∇∇∇ base)
(only for G code) (Z1 for machining surface, face C/Y or X1 for peripheral surface C/Y)
