12.3 Inclined-tool machining in the

tilted plane

Function

In combination with M128 and the new PLANE functions,

inclined-tool

machining in 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 via incremental traverse
of a rotary axis

Retract the tool

Define any PLANE function; consider the positioning behavior

Via a straight-line block, traverse to the desired incline angle in the
appropriate axis incrementally

Activate M128

Example NC blocks:

IB

Inclined-tool machining in a tilted machining plane only
functions with spherical cutters.
