摘要： A machining method for three-dimensional open flow channel using high-speed arc discharge layered sweep, which arranges an axial line of an installation shaft of a tool electrode with six degrees of freedom to be perpendicular to an axial line of a to-be machined work piece in an arc discharge process, with the tool electrode sweeping in a closed path in a plane or a curved surface perpendicular to the installation shaft, wherein the path of the sweeping satisfies: a space of an enveloped space being formed by the tool electrode moving in the path and being coincident with a removed portion of the work piece does not exceed a preset machined cavity of the flow channel. The present invention is based on high-speed arc discharge of hydrodynamic arc breaking and realized layered milling and surface machining for three-dimensional open flow channels.

摘要： This fine hole electrical discharge machine applies voltage between a fine hole machining electrode and a workpiece to cause discharge, and machines a fine hole in the workpiece by using energy of the discharge. The fine hole electrical discharge machine comprises: a bendable guide tube having a hollow portion through which the electrode is inserted; and a tube holder that supports the leading end of the guide tube and allows the leading end of the guide tube to be inclined at a desired angle. Thus, even when the workpiece has a complicated shape, like a blisk, having a large number of turbine blades arranged in the circumferential direction, a fine hole can be machined by accurately positioning the electrode so as to orient the electrode toward a target machining point on a surface of the workpiece without involving interference with the workpiece.

摘要： A method for fabricating an airfoil includes forming a diffuser section in an exterior surface of the airfoil. The diffuser section is defined by at least an outer surface and an inner surface that converge at a stop surface. The method also includes positioning a drilling element of a drilling device on the stop surface. The method further includes orienting the drilling element at a first angle relative to the exterior surface. The method also includes forming, using the drilling element, a cooling channel extending through the airfoil from the stop surface to an interior surface, thereby forming the cooling channel at substantially the first angle.
