Erosion electrodes and associated devices, systems, and methods for providing improved performance during a process driven by FEED and facilitated by fluid flushing of a worksite is disclosed. Use of erosion electrodes having varying cross-sectional geometries result in customizable channels, within which the FEED process may proceed, improving efficiency and efficacy of the process as the erosion electrode is advanced longitudinally into a workpiece.

Customized and varying cross-section electrodes

A device and method for removal of fasteners by Electro-discharge Machining (EDM) such that portions of the fastener, such as a flange, may be separated from other portions of the fastener, such as a shank.

Method of separating fastener shanks from heads or frames

The hand-held electro-discharge device to remove boluses of material from a workpiece. In some implementations a conductive electrode and its supporting ground pin are immersed in a dielectric fluid contained in a hood or cavity near or at the electrode's distal tip an removably sealed to a conductive workpiece. A flushing inlet and outlet in fluid communication with said hood provide a flushing fluid, which may also be a dielectric fluid to remove FOD and cool.

Advanced flushing for workpiece erosion

The hand-held electro-discharge machining fastener removal device of this invention brings an EDM electrode and its supporting ground pin and dielectric fluid structure to a fastener in a workpiece, such as an aircraft fuselage. The hand-held device brings the dielectric fluid, power supply, and control system structure to the fastener in a compact tool to permit EDM machining to be brought to large structures.
