    Abstract: A method of machining a work-piece formed of titanium-based material, using a machining apparatus, is described. The method includes the steps of providing an electrically-conductive electrode contained within a spindle assembly, in a pre-selected distance and position relative to the titanium-based work-piece; while electrically powering the electrode and the work-piece with a power supply. In the process, fluid electrolyte is circulated through at least two pathways in the machining apparatus—an internal conduit within the spindle assembly; and an external conduit. The charged electrode is moved relative to the work-piece in a plunging motion, to remove material from the work-piece at a relatively high rate, using a high-speed electro-erosion (HSEE) process.

    Abstract: A computer-implemented method for forming a three-dimensional workpiece from a block of material using a fluid jet cutting device is implemented by a fabrication system. The method includes receiving an indication of the geometry of the workpiece and generating a three-dimensional tool path to control a cutting head to form the workpiece. Generating the tool path includes receiving an indication of a desired cutting surface on the workpiece, determining a length of the cutting surface, and designating a plurality of waypoints along an edge of the cutting surface. Generating the tool path also includes determining at least one geometric parameter of the cutting surface at each waypoint of the plurality of waypoints, and calculating a speed of the cutting head at each waypoint of the plurality of waypoints based on the determined geometric parameter such that the speed of the cutting head varies along the cutting surface length.

    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 circuitis 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.
