(3) When updating the workpiece coordinate system offset amount
Assume that the previous workpiece coordinate system offset amount is as follows.
X = −10.000
N100
N101
N102
M02 ;
-X

At N101, the G54 workpiece position display data will change before and after the
workpiece coordinate system is changed with G10.
X = 0 X = +5.000
→
Y = 0 Y = +5.000

G90 G10 L2 P1 X−10.000 Y−10.000 ;
G90 G10 L2 P2 X−20.000 Y−20.000 ;
