Setting Datums using NOTE/SET Function
The NOTE/SET function is useful for setting a datum when a tool is
under load, and the diameter of the workpiece is not known.
To use the NOTE/SET function:
Press the DATUM hard key.
The cursor will be in the Datum Number field.
Enter the datum number, and press the DOWN
ARROW key to go to the X AXIS field.
Turn a diameter in the X axis.
Press the NOTE soft key while the tool is still cutting.
Retract from the current position.
Turn the spindle off, and measure the workpiece
diameter.
Enter the measured diameter, for example, 15 mm,
and press Enter.
Remember to ensure the ND 522/523 is in diameter
display mode (Ø) to input a diameter value.
