Abstract
The present invention provides an apparatus and method for an adaptive machining and weld repair process useful for repairing airfoils, particularly damage to an airfoil leading edge and tip. The process first machines away damaged portions of the airfoil. Next, the actual profile of the airfoil subsequent to the removal of the damaged material is measured using a Coordinate Measuring Machine. The data is then used to generate a deformation profile. Filler material is then added to the machined area using the data of the deformation profile to produce an airfoil that approximates the ideal shape of a restored airfoil. At this point, the actual profile of the welded airfoil is measured using the Coordinate Measuring Machine. The data is then used to generate a deformation profile and the airfoil is machined using the date of the deformation profile to produce that shape. The adaptive technology minimizes the amount of stock on material that needs to be removed by hand. The technique thereby significantly reduces costly manual processing.
