4-4 Starting Cutting (NC-code Mode)
Determining the Reference Position for Cutting
Coordinate Systems and Origins
Workpiece Coordinate Systems
With NC codes, the coordinate system that lets you freely set the origin wherever you want is called the "workpiece coordinate
system." The setting for the workpiece coordinate origin, gives you added freedom over RML-1.
NC codes have six workpiece coordinate systems, G54 through G59. You can select which one of these you want to use. The
six workpiece coordinate systems are independent of one another, which means that, in effect, you can preset six different
origins.

For detailed information, refer to the "NC Code Reference Manual."
Selection of the Location of the Origin and the Workpiece Coordinate System
The location on the workpiece to make the origin varies according to the NC program. Set the origin at the location expected
by the NC program.
The selection of which of the six workpiece coordinate systems to use depends on the NC program. Check the NC pro-
gram.
Coordinate View
On this machine, you can any one of the six workpiece coordinate systems or the machine coordinate system.
How to Set the Origin
Several methods exist for setting the origin in the NC-code mode, but this section explains an example of making the setting
in which the NC program uses G54.
Procedure

In VPanel, click the [Base Point]
icon.
Selected coordinate system
This switches only the coordinate view. Cutting opera-
tions are not affected.
