Abstract
Dynamic unbalance of a rigid rotor is corrected by machining the rotor in a direction parallel to the rotor axis of said rotor by subtracting or adding weights corresponding to a corrective weight in two planes for compensating initial unbalanced vectors corresponding to correction angle directions and corrective weights in the planes. Prior to effecting the machining, center of gravity position of a corrective machining weight is calculated for effecting corrective machining in the axial direction; the corrective machining corresponds to the corrective weight. The initial unbalanced vectors in the two planes are corrected into unbalanced vectors in new planes respectively including the centers of gravities of the corrective machining weights determined during the calculating step. Correction angular positions and corrective machining weights around the respective planes are obtained by repeating the calculating and correcting steps.
