Electrochemical micromachining using flat electrolyte jet

This paper describes the development of a novel machining method capable of micro-milling and electrochemical turning using a flat electrolyte jet. The workpiece is machined locally in the area hit by the jet which moves when an electrical current is applied to it. Use of a flat jet in place of a cylindrical jet improves milling speed, and turning process is realized by the flat jet hitting the surface of the rotating cylindrical workpiece. Since depth of cut can be determined by the electrical current or dwelling time of the jet on the surface, there is no need for precise positioning of the nozzle against the workpiece. (C) 2011 CIRP.
