  • ELECTROCHEMICAL MACHINING INNER CONTOURS OF GAS TURBINE ENGINE COMPONENTS
    Publication number: 20170274451
    Abstract: A method of forming a component for a gas turbine engine, including: casting a component around a ceramic core, wherein the ceramic core forms a pilot channel (40) in the component, the pilot channel oriented from a base (176) to a tip (20) of the component; sinking an ECM electrode into the pilot channel; and enlarging the pilot channel to form an inner surface of an external wall (120) of the component via electro-chemical machining, wherein a contour (94) of the inner surface is different than a contour of the pilot channel.
