Peripheral surface Y:
C0 Reference point
X0 Reference point in X direction (abs.)
X1 Depth with reference to X0 (abs. or inc.)
DYZ Maximum infeed in the YZ plane
Plane infeed in %: Ratio of plane infeed (mm) to milling cutter diameter (mm)
UYZ Finishing allowance in plane
UX Finishing allowance in depth
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.
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.
