7. COORDINATE SYSTEMS
NC FUNCTION
89
With G52 commanded, the local coordinate system with the commanded
position as zero point can be set. Once the local coordinate system is set,
values specified in subsequent move commands are regarded as
coordinate values on that coordinate system. Coordinates once set is
valid till a new G52 is commanded. This is used when, for example,
programming of a part of the workpiece becomes easier if there is a zero
point besides the workpiece coordinates’ zero point.

When local coordinate system is set, local coordinate system 1 - 6,
corresponding to workpiece coordinate system 1 - 6 is set. Distance
between zero points are all the same preset value.
If G52 IP0; is commanded, local coordinate system is canceled.
