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.
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 473).
Inclined-tool machining via incremental traverse

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
