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.
With 45° swivel heads and tilting tables you can also
define the incline angle as a space angle. Use the TCPM
FUNCTION
(see "TCPM FUNCTION (Software Option 2)" on
page 513).
