12. COMPENSATION FUNCTION
If the center of the arc is identical with the start position or end point, P/S
alarm (No. 038) is displayed, and the nozzle will stop at the end position
of the preceding block.
Alarm(No.038)is displayed and the tool
N5 G01 X100.0 ;
N6 G02 X100.0 I0 J0 ;
N7 G03 Y–100.0 J–100.0 ;
Beam center path
The offset direction is decided by G codes (G41 and G42) for beam radius
and the sign of cutter compensation value as follows.
Sign of offset amount
G41 Left side offset Right side offset
G42 Right side offset Left side offset
The offset direction can be changed in the offset mode. If the offset
direction is changed in a block, a vector is generated at the intersection
of the beam center path of that block and the beam center path of a
preceding block. However, the change is not available in the start–up
block and the block following it.
The center of the arc is identiĆ
cal with the start position or
the end position
