Axis identifiers
The two geometry axes perpendicular to one another are usually called:
Longitudinal axis = Z axis (abscissa)
Transverse axis
Workpiece zero
Whereas the machine zero is permanently defined, the workpiece zero can be freely selected
on the longitudinal axis. Generally the workpiece zero is on the front or rear side of the
workpiece.
Both the machine and the workpiece zero are on the turning center. The settable offset on the
X axis is therefore zero.
