7.3 LOCAL COORDINATE SYSTEM
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.
