Abstract: A method for finishing a film cooled article includes providing a film cooled article including at least one inner cooling plenum and at least one opening connecting the inner cooling plenum to an exterior surface of the film cooled article, positioning a machining element in contact with the exterior surface of the film cooled article, automatically moving the machining element along the exterior surface while maintaining contact between the machining tool and the surface, identifying an actual position of at least one film opening based on sensory feedback from the machining element using a controller, removing material from the exterior surface at the at least one film opening using the machining element, thereby creating a depression at the at least one film opening.

Abstract: A system and methods are provided for grinding a workpiece. In one embodiment, a method includes controlling rotation of a workpiece, wherein the workpiece is rotated relative to a first axis, and controlling grinding of the workpiece by a first grinding tool to shape the workpiece, wherein the first grinding tool is rotated relative to a second axis. The method may also include controlling grinding of the workpiece by the grinding tool and rotation of the workpiece to provide grinding of the workpiece with a generally constant surface footage.

Abstract: An example component finishing method includes immersing a surface of a component within a fluid during a finishing process. The method heats fluid near the surface during the finishing to create a convection current within the fluid that carries a byproduct of the finishing away from the surface.

Abstract: A grinding tool is provided that includes an axial grinding wheel having a circumferential cutting slot formed therein, the cutting slot having a cross-sectional profile that includes a floor having a first radius of curvature, a first side wall rising upward from the floor and having a second radius of curvature, a second side wall rising upward from the floor opposite the first side wall and having a third radius of curvature. At least one radius of curvature corresponds to a surface, such as a leading edge of a gas turbine engine airfoil.

Abstract: An example component machining method includes immersing a surface of a component within a fluid during a machining process. The method heats the surface during the machining to vary the machining process at the surface relative to other surfaces of the component.

Abstract: An example electrical discharge machining electrode assembly includes an electrode base and an electrode coating containing diamond that is electroplated to the electrode base.
