Overview

The reference point for programming a workpiece is always the workpiece zero. The workpiece
zero is determined on the workpiece edge.
Manual measurement
To measure the zero point manually, you need to traverse your tool manually up to the
workpiece. Alternatively, you can also deploy a grinding tool with known length.

Setting the edge

The workpiece lies parallel to the coordinate system on the work table. You measure one
reference point in one of the axes (X, Y, Z).
