3.1.5Zero offset

The actual position memory, and therefore the actual position display, are referred to the machine zero point ºMº after traversing to the reference point.

The machining program for the workpiece is referred to the workpiece zero point ºWº.

Machine zero point ºMº and workpiece zero point ºWº are not identical. The dimensions between the machine zero point ºMº and the workpiece zero point ºWº can vary, depending upon the type and fixing of the workpiece. The zero offset will allow for this during program operation.
