Abstract:
A method of repairing a turbomachine rotor wheel including a first outer circumferential edge extending to a second outer circumferential edge through a circumferential surface, a dovetail interface extending across the outer circumferential surface between the first and second outer circumferential edges, and a bucket mounted to the dovetail interface includes identifying a defect on one of the first and second outer circumferential edges of the rotor wheel adjacent the bucket, securing the bucket in the dovetail interface to substantially constrain axial movement, and removing a portion of the one of the first and second outer circumferential edges to remove the defect.
