1. A method of calibrating a machine having a first rotatable portion for holding a workpiece, the first rotatable portion having a first feature associated therewith, the method comprising the steps of:
- (i) using a measurement probe to determine a position of the first feature,(ii) rotating the first rotatable portion through an angle to a new position,(iii) using said measurement probe to determine the new position of the first feature, and(iv) calculating a position of an axis of rotation of the first rotatable portion using the position determined in step (i) and the new position determined in step (iii).

Abstract
Methods are described for calibrating a turning machine having a first rotatable portion or chuck for holding a workpiece. The first rotatable portion has a first feature associated therewith. The method comprises the steps of using a measurement probe to determine the position of the first feature, rotating the first rotatable portion through an angle, and using said measurement probe to determine the new position of the first feature. The extension of the technique to swivel head mill-turn machines is also described.

10. A method of determining a position of an axis of rotation of a rotatable portion of a machine as a function of displacement along a translational axis of the machine, the rotatable portion holding a measurement probe, wherein the method comprises the steps of:
-
(A) determining a position of the axis of rotation of the rotatable portion by; (i) using the measurement probe to determine a position of a first feature of the rotatable portion, (ii) rotating the rotatable portion through an angle to a new position, (iii) using said measurement probe to determine the new position of the first feature, and (iv) calculating a position of the axis of rotation of the rotatable portion using the position determined in step (i) and the new position determined in step (iii); (B) translating the measurement probe; and (C) repeating step (A) to determine a further position of the axis of rotation of the rotatable portion. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
