20130206733 | EDM METHOD FOR MULTI-LOBED COOLING HOLE - A method for forming a cooling hole extending from an inlet on a first surface of a wall to an outlet on a second surface of the wall includes forming a diffusing section of the cooling hole, and a trailing edge on the outlet by electrical discharge machining, and forming longitudinal lobes in the diffusing section. The metering section extends from the inlet on a first surface of the wall towards the second surface of the wall. The diffusing section extends from the outlet to one end of a metering section located between the inlet and the outlet. The outlet is substantially linear or convex at the trailing edge and the lobes are separated by longitudinal ridges. | 08-15-2013 |
20140183164 | NON-LINE OF SIGHT ELECTRO DISCHARGE MACHINING SYSTEM - 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. | 07-03-2014 |
20140186164 | NON-LINE OF SIGHT ELECTRO DISCHARGE MACHINED PART - 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. | 07-03-2014 |
20140300728 | On-The-Fly Dimensional Imaging Inspection - A method and system are provided for inspecting a plurality of target features arrayed in spaced arrangement on a surface of a target object, such as but not limited to inspection of the location of cooling air holes in the surface of a turbine blade or vane. | 10-09-2014 |
20140300729 | Probe for Inspection System - A method and system are provided for inspecting a plurality of target features arrayed in spaced arrangement on a surface of a target object, such as but not limited to inspection of the location of cooling air holes in the surface of a turbine blade or vane. | 10-09-2014 |
