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 in a tilted machining plane only
functions with spherical cutters.
Inclined-tool machining via incremental traverse
of a rotary axis
U
Retract the tool
U
Activate M128
U
Define any PLANE function; consider the positioning behavior
U
Via a straight-line block, traverse to the desired incline angle in the
appropriate axis incrementally
