Inclined-tool machining via normal vectors
U Retract the tool
U Activate M128
U Define any PLANE function; consider the positioning behavior
U Execute program with LN block in which the tool direction is defined
by a vector
Example NC blocks:
Only one directional vector can be defined in the LN block.
This vector defines the incline angle (normal vector NX, NY,
NZ
, or tool direction vector TX, TY, TZ).
