5.6 Contour milling
End face Y:
CP Reference point
Z0 Reference point in Z direction (abs.)
Z1 Depth with reference to Z0 (abs. or inc.)
DZ Maximum depth infeed (Z direction)
UXY Finishing allowance in plane
Peripheral surface Y:
C0 Reference point
X0 Reference point in X direction (abs.)
X1 Depth with reference to X0 (abs. or inc.)
DX Maximum depth infeed (X direction)
UYZ Finishing allowance in plane
Retraction If more than one approach point is necessary, specify the retraction height to which
mode the tool retracts between approach points.
If there are no spigots or other elements in the machining range higher than Z0 (X0),
Z0 + safety clearance (X0 + safety clearance) can be programmed as the retraction
mode.

Spigot
milling
Parameters
T, D, F, S, V See Sec. "Creating program blocks".
Position Select from 8 different positions:
Clamp/release spindle (for End face Y/Peripheral surface Y only)
The function must be set up by the machine manufacturer.

 To retraction plane
 Z0+safety clearance (for end face/end face C and end face Y only) or
X0+safety clearance (for peripheral surface/peripheral surface C and peripheral
surface Y only)
If you have planned edge breaking, mill a chamfer after that.
Press the "Milling", "Contour milling" and "Spigot milling" soft keys.
