Program segments N3~N5 are for the first workpiece, within G54 WCS; program segment N6
drills the hole for the second workpiece of the same batch within G55 WCS; program segment N7 drills
the third hole for the third workpiece of the same batch within G56 WCS.
Aiming at all WCSs, public offset is used to adjust the workpiece origin of X, Y and Z axes, without
changing the offset value of G54~G59.
The relationship of workpiece offset, tool offset and public offset is illustrated as below:
Workpiece coordinate = Machine coordinate – Workpiece offset – Tool offset – Public offset
