Patent ID: 7472478

Claim:
A method for restoring a worn edge of an airfoil comprising the steps of: machining away damaged material from a damaged airfoil edge so as to expose a weld surface; laser depositing new material on the weld surface so as to create a weld-repaired airfoil having actual dimensions; automatically measuring the actual dimensions of the weld-repaired airfoil using a CMM system so as to generate an actual geometry; deforming the actual geometry so as to develop a deformation geometry by: defining a set of streamlines on an airfoil surface, defining a set of cross curves that intersect one or more of the streamlines thereby establishing surface points at each such intersection, associating nominal surface data with each surface point, defining a set of inspection nominal points that fall on streamlines and cross curves, measuring an actual blade shape at each inspection nominal point to establish shape deviation data, and interpolating the shape deviation data with reference to the surface points; and machining the component according to the deformation geometry.
