13.3 Inclined-tool machining in a tilted plane
(option 9)
Function
In combination with M128 and the new PLANE functions, inclined-
tool machining on a tilted machining plane is now possible. Two
possibilities are available for definition:
Inclined-tool machining via incremental traverse of a rotary axis
Inclined-tool machining via normal vectors
Inclined-tool machining in a tilted machining plane only
works with spherical cutters. If you are using 45° swivel
heads and tilting tables, you can also define the incline
angle as a spatial angle. Use FUNCTION TCPM for this
purpose.

Inclined-tool machining via incremental traverse of a
rotary axis
Retract the tool
Define any PLANE function; consider the positioning behavior
Activate M128
Via a straight-line block, traverse to the desired incline angle in
the appropriate axis incrementally
