AN ELECTRO-DISCHARGE MACHINING TOOL AND A METHOD OF USING THE SAME

摘要

An electro-discharge machining (EDM) device (100) comprises a housing (110), an erosion electrode, a ground electrode (150), and a dielectric inlet (160). The housing (110)is configured to be positioned on a surface of a workpiece (120) and proximal to a fastener (130) to be eroded. The planar erosion electrode (140) is positioned at least partially within the housing (110), with the erosion electrode (140) being movable relative to the housing in a first axis (142). The first axis (142) is substantially normal to a longitudinal axis (132) 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.
