Beschreibung
Zusammenfassung:	A method of repairing a turbomachine rotor wheel (2) including a first outer circumferential edge (10) extending to a second outer circumferential edge (11) through a circumferential surface, a dovetail interface (20) extending across the outer circumferential surface between the first and second outer circumferential edges (10, 11), and a bucket (25) mounted to the dovetail interface (20) includes identifying a defect on one of the first and second outer circumferential edges (10, 11) of the rotor wheel (2) adjacent the bucket (25), securing the bucket (25) in the dovetail interface (20) to substantially constrain axial movement, and removing a portion (106, 108) of the one of the first and second outer circumferential edges (10, 11) to remove the defect.
