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 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 506)
Inclined-tool machining via incremental traverse
of a rotary axis
Retract the tool
Activate M128
Define any PLANE function; consider the positioning behavior
Via an L block, traverse to the desired incline angle in the appropriate
axis incrementally
Example NC blocks:
...
12 L Z+50 R0 FMAX M128
13 PLANE SPATIAL SPA+0 SPB-45 SPC+0 MOVE SET UP50 F1000
14 L IB-17 F1000
