<p>The method includes the steps of: mounting the rotor 12 in a machine 10 with chucks 14,16 capable of rotating the rotor about its axis and performing calibration for each of first, second and third axial planes. This calibration includes: attaching a calibration weight of known mass to a surface of the rotor in that plane; causing the rotor to rotate about its axis; determining the effect of the balancing weight attached in that plane on the unbalance of the rotor; storing a calibration value indicative of said effect; and causing the rotor to rotate about its axis; determining the unbalance of the rotor; accessing data representative of a set of discrete balancing masses; determining, using the stored calibration values, a selection of one or more balancing weights each to be attached to the rotor in a respective one of the axial planes, the balancing weights being selected from a set of balancing weights having respective masses corresponding to the set of discrete balancing masses, the selection of weights and respective one of the first, second or third axial plane in which each weight is to be placed providing an optimal correction of any unbalance of the rotor from all possible permutations of available balance weights and axial planes, attaching each of the selected balance weights to a surface of the rotor in its selected axial plane.</p> |
