Abstract: A milling machine calibration technique, and article of manufacture are described. The article comprises a calibration fixture, together with a calibration pin. The calibration fixture preferably is shaped as a cube, and each of the side faces of the cube comprise a set of indentations (dimples or features) that are configured in a predetermined pattern. A preferred pattern is a “5-dimple” pattern. To find a mapping between axis coordinates (of a mill spindle) and the mill mandrel at some orientation, the calibration fixture is inserted into the mandrel, and the calibration pin is inserted into a collet. Using an x-axis directional position error-based probing mechanism, the system then registers the exact position of each of the five (5) dimples on the surface of the die. Using the positional information so determined, spindle-mandrel spatial relationships for one or more orientations of the mandrel are then identified for calibration purposes.
