Abstract: A laser machining method includes directing, from an F-theta lens having a long focal length of greater than about 250 millimeters, a laser beam at a non-perpendicular beam tilt angle from an optical axis of the lens having a top-hat profile and a narrow beam divergence angle of between about 1 degree and about 3 degrees towards a workpiece on a stage movable in at least an X-direction and a Y-direction, engaging the directed laser beam with the workpiece disposed in the usable field of view, moving the workpiece and the directed laser beam relative to each other, and removing portions of the workpiece with the directed laser beam to define a machined surface.

Abstract: An electrochemical machining system for machining a conductive work piece is provided. The system includes a drilling tool configured to remove material from the conductive work piece. The drilling tool is configured to advance within the conductive work piece along a tool path to form a bore hole having a variable geometry that extends through the conductive work piece when the material is removed therefrom. The system further includes an inspection device configured to determine a position of the drilling tool along the tool path, and a controller configured to communicate with the inspection device. The controller is further configured to compare the tool path to a nominal tool path, and determine a position error of said drilling tool, the position error defined by a difference between the tool path and the nominal tool path.

Abstract: A method for electroerosion machining includes providing an electrode assembly comprising an electrode body having a tube-shaped body that defines a hollow interior and one or more inserts affixed to the electrode body to form a cutting surface on the electrode assembly, positioning the electrode assembly adjacent a workpiece to be machined, and providing power to the electrode assembly so as to energize the electrode assembly, with the electrode assembly and the workpiece being at opposite electrical polarities. The method also includes advancing the electrode assembly through the workpiece, with a working gap being maintained between the inserts and the workpiece across which a pulse electric current is passed to remove material from the workpiece, wherein, upon advancing the electrode assembly through the workpiece, a core is formed that is completely separated from a remainder of the workpiece and is contained within the hollow interior of the electrode body.

Abstract: A multi-loop controller component for an electric discharge machining (EDM) system includes a plurality of power loop circuits coupled to an output of a power supply of the EDM system and configured to receive DC electric power from the power supply. Each power loop circuits electrically-isolated from other power loop circuits. The multi-loop controller component also includes a plurality of transistors. Each transistor is coupled to a respective power loop circuit and is configured to switch between an ON state and an OFF state to generate a pulse of the DC electric power through the respective power loop circuit. In addition, the multi-loop controller component has a drive controller coupled to the plurality of transistors. The drive controller is configured to transmit at least one control signal to at least one of the transistors to facilitate switching the transistor between the ON state and the OFF state.

Abstract: A gradient coil comprises a curved conductor, which is tubular and has a general spiral shape. The curved conductor is formed by a process comprising depositing at least one non-conductive material layer by layer to form a substrate, and coating at least a portion of a surface of the substrate with a conductive material. The substrate has a shape matching with the general spiral shape of the curved conductor. Embodiments of the present disclosure further refer to a method for manufacturing the gradient coil.
