Parameter Description
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 (only for Shop‐ Reference point Z
Turn)
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 (only for Shop‐ Reference point Z
Turn)
Peripheral surface C: The positions refer to the reference point:
Y0 or C0 Reference point Y or reference point length 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)
∅ Diameter of pocket
Z1 Depth referred to Z0/X0 (inc) or pocket depth (abs) - (only for ∇, ∇∇∇ or ∇∇∇ edge)
DXY
● Maximum plane infeed
● Maximum plane infeed as a percentage of the milling cutter diameter
DZ Maximum depth infeed – (only for ∇, ∇∇∇ or ∇∇∇ edge)
UXY Plane finishing allowance – (only for ∇, ∇∇∇ or ∇∇∇ edge)
UZ Depth finishing allowance – (only for ∇, ∇∇∇)
