G40/G41/G42: Cutter Radius Compensation Commands
Format: G41
（
or G42
）
Rn
.
Program segment to be compensated.
.
G40
Notes:
G41 is to compensate a half diameter of flame leftwards along the machining path.
G42 is to compensate a half diameter of flame rightwards along the machining path.
G40 represents end of offset.
Since cutter compensation is made automatically, there must be G00 Quick Move command before G41 or G42
commands so as to assure the position of cutting torch is corrected. Behind G40 the end mark of cutter compensation, a
G00 command is necessary to adjust the position back.
