Inclined-tool machining via normal vectors
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).
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:
...
12 L Z+50 R0 FMAX M128
13 PLANE SPATIAL SPA+0 SPB+45 SPC+0 MOVE SET UP50 F1000
14 LN X+31.737 Y+21.954 Z+33.165
