Inclined-tool machining via normal vectors
 Retract the tool
 Activate M128
 Define any PLANE function; consider the positioning behavior
 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 an LN block.
This vector defines the incline angle (normal vector NX, NY,
NZ,
or tool direction vector TX, TY, TZ).
