摘要： A method of machining cooling holes in a component includes the steps of inserting an electro discharge machining guide that houses an electrode into an internal cavity of a component, and machining a cooling hole into a wall of the component with the electrode. A gas turbine engine component includes first and second spaced apart walls providing an internal cavity. The first wall has outer and inner surfaces. The inner surface faces the internal cavity. A cooling hole extends through the first wall from the inner surface to the outer surface. The cooling hole includes entry and exit openings respectively provided in the inner and outer surfaces. The exit opening includes a cross-sectional area that is smaller than a cross-sectional area of the entry opening.

摘要： An electro discharge machining system includes a guide having first and second portions that are non-colinear with respect to one another. A consumable electrode is housed within the guide and configured to drill cooling holes in a component. A controller is programmed to position the guide and electrode to a desired position with respect to the component. An electro discharge machining guide includes first and second portions that are non-colinear with respect to one another and that include a passage configured to receive an electrode.
