    Abstract: A system for forming features within composite components includes a tubular electrode extending along a longitudinal direction from a proximal end to a distal end. The distal end is, in turn, configured to be positioned relative to a machining surface of the composite component such that a spark gap is defined between the distal end and the machining surface. Furthermore, the tubular electrode further extends in a radial direction between an inner surface and an outer surface, with the inner surface defining a central passage configured to supply a dielectric fluid to the machining surface. The outer surface of the tubular electrode includes at least one a channel defined therein or a non-circular cross-sectional shape.

    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.

    Abstract: Electrodes for and methods of electrical discharge machining are provided. For example, a method for forming a feature in a ceramic matrix composite (CMC) component comprises repeatedly advancing an electrode into and retracting the electrode from the CMC component until a desired depth is reached, where the electrode has a head end, a tip end, and a shaft extending from the head end to the tip end. The shaft has a first side and a second side each recessed inward such that the head end and the tip end are wider than the shaft. A method for forming a feature in a CMC component also may include feeding a dielectric fluid into the feature utilizing the recessed sides. In some embodiments, electrodes may include a shaft extending from a head end to a tip end and a central plane, where the shaft is recessed widthwise toward the central plane.
