Abstract: This paper studies on a newly developed method, WEDM in gas, and discribes the features of finishing dry-WEDMed surface, such as narrower discharge gap length, higher surface straightness accuracy and no electrochemical etching actions. Low-speed WEDM removal rate in gas can be improved by increasing the wire winding speed. High-speed WEDM in gas has a significant advantage as high removal rate beyond the abovementioned good points, which is available for improving conventional high-speed WEDM quality.
