Programming: Multi-Axis Machining
12.3 Inclined-tool machining in a tilted plane
Inclined-tool machining via normal vectors
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).
Retract the tool
Define any PLANE function; consider the positioning behavior
Activate M128
Execute program with LN blocks in which the tool direction is
defined by a vector
