End face Y:
CP Reference point
Z0 Reference point in Z direction (abs.)
FS Chamfer width, inc
ZFS Insertion depth for tool tip; abs or inc
Peripheral surface Y:
C0 Reference point
X0 Reference point in X direction (abs.)
FS Chamfer width, inc
ZFS
Insertion depth for tool tip; abs or inc
Retraction If more than one insertion point is necessary, specify the retraction height to which
mode the tool retracts between insertion points:
If there are no islands larger than Z0 (X0) in the pocket area, Z0 + safety clearance
(X0 + safety clearance) can be programmed as the retraction mode.

5.6.11 Milling a contour spigot (roughing)

5-302
 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)
The "Mill spigot" function is used when you want to mill a spigot on the
end face or peripheral surface.
Before you mill the spigot, you must first enter a blank contour and
then one or more spigot contours. The blank contour defines the outer
limits of the material. The tool moves at rapid traverse outside this
area. Material is then removed between the blank contour and spigot
contour.
You can select the machining mode (roughing, finishing, or chamfer)
for milling. If you want to rough and then finish, you have to call the
machining cycle twice (Block 1 = roughing, Block 2 = finishing). The
programmed parameters are retained on the second call. For more on
finishing, see Sec. "Finishing the contour spigot".
If you only program a blank contour without a second contour for a
spigot, you can face mill the blank contour.
