Workpiece Coordinate System
As a set of right-hand coordinate system for the programmer, workpiece coordinate system is
used in programming. To establish it, the programmer can select a given point on the workpiece as
the origin (also called program origin). The origin of workpiece coordinate system (namely the
workpiece origin) is fixed relative to a certain point on the workpiece, so it can be floating with respect
to the origin of mechanical coordinate. The origin of workpiece coordinate system should be selected
meeting such conditions as simple programming, simple dimension conversion and small machining
errors caused.
Workpiece offset corresponds to the coordinate systems G54, G55, G56, G57, G58 and G59.
After the system is opened, the default coordinate system is G54, and the relation between workpiece
offset and mechanical coordinate system is as shown in Fig. 4-2.

Fig. 4-2 The relation between workpiece offset and mechanical coordinate system
One, two or several workpiece offsets can be used in the machining program. As shown in Fig.
4-3, three workpieces are installed on the work table, so each workpiece has a workpiece origin
corresponding to the G code of workpiece coordinate system. Drill a hole on each of the workpiece,
with calculation depth as Z-0.14, and the programming example is as follows.
