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.
Claims38
A method of calibrating a turning machine having a first rotatable portion for holding a workpiece, the first rotatable portion having a first feature associated therewith, wherein the method comprises the steps of;
- (i) using a measurement probe to determine the position of the first feature,
- (ii) rotating the first rotatable portion through an angle, and
- (iii) using said measurement probe to determine the new position of the first feature.
A turning machine comprising a first rotatable portion for holding a workpiece, the first rotatable portion having a first feature associated therewith,
- wherein the turning machine comprises a machine controller that is arranged to determine the position of the first feature, rotate the first rotatable portion through an angle and determine the new position of the first feature.
