Wire Electrochemical Machining

In view of major problems for the current metal cutting technology, a combined sand coated wire electrochemical machining technology is introduced. This method uses porous silicon carbide coated in metal wire electrode for grinding and electrolytic machining, which has both wire electrolytic and sand wire grinding characteristics, and greatly improves the cutting efficiency. The composite wire electrochemical cutting technology principle is analyzed. The method for determining the main process parameters is presented, and the effectiveness of its application in thin-walled metal pipe cutting is validated.

Wire Electrochemical Machining

Wire electrochemical machining (WECM) has great advantages and potential for fabricating parts with ruled surfaces made of difficult-to-machine materials. Characterized by a relatively short flow path, a pulsating radial electrolyte supply in WECM is proposed to improve the machining capability for thick workpieces. The tool is a tube electrode with a line of micro-holes on cylindrical surface. This paper introduces research into the processing of micro-holes in the tube electrode using a rotating helical electrode. The quantitative relationship among the feed rate, the applied voltage, and the diameter of the outlet holes was determined experimentally. A tube electrode with holes of varying diameters was fabricated by adjusting the applied voltage. Using it as a tool electrode, kerfs with a length of 10 mm and an averaged width of 0.903 mm were machined at a feed rate of 6 μm/s in a 30 mm-thick block, and there was no short circuit during processing. It was shown experimentally that using a tube electrode with holes of varying diameters as a tool electrode provides better process capacity for pulsating radial electrolyte supply in WECM.
