2. Setting a workpiece coordinate system using G54 to G59
This method is used to set up to six workpiece coordinate origin points and select a coordinate system from among these by means of
the program.
The workpiece coordinate systems 1 through 6 are set by specifying the amount of shift (the amount of workpiece origin point offset)
from the machine coordinate origin point to the workpiece coordinate origin point. Each workpiece coordinate system is set using the
PNC-3200's display. (Refer to the "User's Manual 3 Cutting Using NC-Codes" for information on making this setting.)

It is also possible to shift the six set workpiece coordinates by a desired distance at one time. Because the workpiece origin point is
offset, this is called EXOFS (external workpiece origin point offset amount). EXOFS is set with G10 or by using the PNC-3200's
display. (Refer to the "User's Manual 3 Cutting Using NC-Codes" for information on how to make the setting on the PNC-3200.)
