| Research Abstract |
In electrolyte jet machining (EJM), the workpiece is machined only in the area which is hit by the electrolyte jet by applying an electrical current through the jet. To apply this method to the turning process of micro rods, a curved flat jet was newly developed. Then, EJM was applied to machining of cemented carbide using a sodium nitrate aqueous solution without including hazardous sodium hydroxide. Machining with AC current enables more localized machining under the jet than DC current. Use of an insulated nozzle was effective to prevent the nozzle wear.
