12.3 Inclined-tool machining in a tilted
plane (Option #9)
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 "FUNCTION TCPM (Option #9)",
page 469.
Inclined-tool machining via incremental traverse of a
rotary axis
Retract the tool
Define any PLANE function; consider the positioning behavior
Activate M128
Via a straight-line block, traverse to the desired incline angle in
the appropriate axis incrementally
