Defining a workpiece blank

Once you have opened a new NC program, you can define a
workpiece blank. You can define a cuboid by entering the MIN and
MAX points relative to the selected preset.
After you have selected the desired shape for the blank with the
appropriate soft key, the control automatically initiates the workpiece
blank definition process and prompts you to enter the required data.
To define a cuboid-shaped blank:
Press the soft key for the desired shape of the workpiece blank
