Abstract
A method for machining a rotor having a disc and a plurality of integral airfoils projecting outwardly from the disc, according to one aspect of the invention, comprises a step of machining each airfoil with a disc tool having a grinding periphery thereof adapted for removing material from the airfoils. The grinding periphery has a thickness greater than a thickness of an adjacent supporting portion of the disc to permit the grinding periphery to pass a surface of an airfoil in a multi-axis simultaneous motion, thereby matching the grinding periphery with a predetermined geometry of a portion of the airfoil.
