Powder-suspended Electrical Discharge Machining (EDM) produces a mirror-like finish due to the electrical discharge dispersed using powder-suspended fluid. Machined surface roughness differed, however, when several powders are mixed, so the influence of the gap phenomenon was not apparent. To vary the gap phenomenon in powder-suspended EDM, the gap region is observed using a high-speed camera. This report describes observation results in powdersuspended EDM.
