4.7.1.1 Measuring the workpiece zero
The reference point for programming a workpiece is always the workpiece zero. To determine
this zero point, measure the length or the diameter of the workpiece and save it in a zero offset.
This means that the position is stored in the coarse offset and existing values in the fine offset
are deleted.
Calculation
When the workpiece zero / zero offset is calculated, the tool length is automatically taken into
account.
