  • ELECTRICAL-DISCHARGE MACHINING
    Publication number: 20240051049
    Abstract: An electrical-discharge machining tool comprising a ground electrode, a moveable and activatable assistive electrode and a cutting electrode, a first conduit for supplying a dielectric and a second conduit for flushing dielectric material, wherein when used on a dielectric layer on a substrate the assistive electrode is activated and positioned substantially between the ground electrode and the cutting electrode.

  • Electro-discharge machining tool and a method of using the same
    Patent number: 11511361
    Abstract: An electro-discharge machining (EDM) device that includes a housing, an erosion electrode, a ground electrode, and a dielectric inlet. The housing is configured to be positioned on a surface of a workpiece and proximal to a fastener to be eroded. The planar erosion electrode is positioned at least partially within the housing, with the erosion electrode being movable relative to the housing in a first axis. The first axis is substantially normal to a longitudinal axis of the fastener. The ground electrode is conductively connected to the fastener. The dielectric inlet is configured to deliver a dielectric fluid to a region between the erosion electrode and the fastener.
    Type: Grant
