Defining a workpiece blank
After you have created a new program you can define a workpiece
blank. For example, define a cuboid by entering the MIN and MAX
points, each with reference to the selected reference point.
After you have selected the desired blank form via soft key, the
TNC automatically initiates the workpiece blank definition and asks
for the required data:

is saved as default setting. Accept with the
ENT key

the workpiece blank with respect to the reference point, e.g. 0.
Confirm with the

the workpiece blank with respect to the reference point, e.g. 0.
