Abstract:
A method of removing ceramic core material from an internal passage of a superalloy airfoil casting using a CNC controlled fluid spray nozzle in a manner that the fluid spray nozzle is caused to laterally scan and/or rotary orbit an area of one or more openings of one or more passages at an exterior casting surface to improve removal of material residing in the passage.
