Zero offsets

4.5.1 Zero offsets
After reference point approach, the actual value display for the axis coordinates is based on
the machine zero (M) of the machine coordinate system (Machine). The program for machining
the workpiece, however, is based on the workpiece zero (W) of the workpiece coordinate
system (Work). The machine zero and workpiece zero are not necessarily identical. The
distance between the machine zero and the workpiece zero depends on the workpiece type
and how it is clamped. This zero offset is taken into account during execution of the program
and can be a combination of different offsets.
