Study on high-speed WEDM in gas

This paper investigates the influence on finish high-speed Wire-cut Electrical Discharge Machining (WEDM) in atmosphere and emulsion liquid. Experimental results have shown that WEDM in atmosphere offers a series of advantages such as better straightness accuracy and higher removal rate (material removal rate). It was also found that the removal rate increased significantly at a higher wire winding speed, with the straightness got worse at the meanwhile both in atmosphere and emulsion liquid. Considering its better processing quality and higher removal rate, the high-speed WEDM in gas possesses broad prospects for its application.
