Tool Compensation Path
Path of Tool During Tool Compensation
In linear-to-linear or linear-to-circular moves, the position at the end of
the startup block Compensation LEFT (G41), or Compensation RIGHT
(G42), is perpendicular to the next programmed move in the plane.
In either case, the axes moves to a point perpendicular to the next
move during the startup block.
The length of the XY move that activates compensation must be equal
to or greater than the tool radius value. Example: If tool radius equals
0.3750", the vector length of the XY move that activates compensation
must be 0.3750" or greater.
The same applies to Compensation OFF move (G40).
During tool compensation, the CNC performs offset correctly and
automatically. Non-positioning moves such as dwells (except dwell
zero or infinite dwells), coolant, or other auxiliary functions are allowed
(except Optional Program Stop, and Program Stop Mode, these are
not allowed). Moves in the third axis are also allowed during
compensation.
It is recommended to use the previously described Entry
and Exit moves.
