Format
・Tool side offset
G41.2 (or G42.2) IP_ D_ ;
G41.2: Cutter compensation left (group 07)
G42.2: Cutter compensation right (group 07)
IP_: Value specified for axis movement
D_: Code specifying the cutter compensation amount (1 to 3 digits)
NOTE
When a movement perpendicular to the next movement (bit 1
(SUV) of parameter No. 5003 is set to 1) is specified as the
operation performed at the time of startup or cancellation, a move
command such as X_ Y_ Z_ must not be specified in the G41.2
and G42.2 block.
