5.6 Work offset
5.6.1 Function
Machine/
tool zero
The actual values are referred to the machine zero after a reference
point approach. The machining program of the workpiece refers to the
workpiece zero.
Machine zero and workpiece zero need not be identical. Depending
on the type of workpiece and the way it is clamped, the distance
between the machine zero and workpiece zero can vary. In part
program processing this is compensated for by the work offset.
