Abstract
Method and apparatus for repairing an article, such as an air-cooled component, during which at least a portion of the component must be removed and replaced. The method and apparatus make use of one or more workpiece holders adapted to secure and position an component on the apparatus, a multi-axis head adapted for movement relative to the workpiece holder, a nozzle mounted to the multi-axis head and operable to remove at least a portion of the component with a jet of fluid discharged therefrom, an electrical-discharge electrode mounted to the multi-axis head and operable to form surface holes in the component by electrical-discharge machining, and a system for controlling the movement of the multi-axis head so that the waterjet and electrical-discharge machining operations are performed to yield a repaired component that closely duplicates the original.
