Abstract
A method for calibrating a CNC machine comprises mounting a gauge to a table of the CNC machine and calibrating a probe to the gauge mounted on the CNC machine. A total deviation of the probe and an actual table center position from a nominal table center position for a coordinate system associated with the CNC machine are determined. A controller operatively connected to the CNC machine and the probe is programmed to compensate for the total deviation.
