Parameters
T, D, F, S, V See Sec. "Creating program blocks".
Machining
type
Z0 Reference point in Z direction (abs.)
Z1 Depth with reference to Z0 (abs. or inc.)
DXY Maximum infeed in the XY plane (base finishing only)
Plane infeed in %: Ratio of plane infeed (mm)
to milling cutter diameter (mm)
DZ Maximum depth infeed (Z direction) – (edge finishing only)
UXY Finishing allowance in plane
UZ Finishing allowance in depth – (edge finishing only)
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 larger than Z0 in the machining area, "Z0 +
safety clearance" can be selected as the retraction mode.

If you programmed a finishing allowance for the base or edge of the
spigot in spigot milling, you still have to finish the spigot.
Separate blocks must be programmed for finishing the base and/or for
finishing the edge. In each case, the spigot will only be machined
once.
You can program "Path milling" as an alternative to "Edge finishing".
Optimization possibilities are also offered for the approach/retract
strategy and the approach/retract mode. Then program as follows:
1. Contour blank
2. Contour spigot
3. Mill spigot (roughing)
4. Contour blank
5. Path milling (finishing)
6. Contour spigot
7. Path milling (finishing)
Press the "Cont. mill." and "Mill spigot" softkeys.
