The corresponding coordinate systems of workpiece offset are G55, G56, G57, G58, G59 and G54 (the
default coordinate system after the system is opened). Besides, the system also supports extended
coordinate system ranging from G154 to G173. And the relationship of workpiece offset and mechanical
coordinate system is shown in Fig. 3-29.

Fig. 3-29 The Relationship of Workpiece Offset and Mechanical Coordinate System
One, two or multi-workpiece offset can be used in machining program. As shown in Fig. 3-30, three
workpieces are installed on the workbench, and each workpiece holds a workpiece origin relative to G
code of WCS. The programming example is as follows: drill one hole on each of the three workpieces,
with calculation depth as Z-0.14.
