9.9 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
8 Retract the tool
8 Activate M128
8 Define any PLANE function; consider the positioning behavior
8 Via an L block, traverse to the desired incline angle in the appropriate
axis incrementally
Example NC blocks:
Inclined-tool machining in a tilted machining plane only
functions with spherical cutters.
With 45° swivel heads and tilting tables you can also
define the incline angle as a space angle. Use the TCPM
FUNCTION.
