Development of a WEDM system with high machining efficiency

Nowadays, the wire electrical discharge machining (WEDM) is widely accepted in the manufacturing industry. This is because WEDM can machine any conducted material regardless of its hardness. Moreover, WEDM can cut complex geometries and micro parts with a very small thickness and provide very high accuracy and low surface roughness. Many researches about WEDM have been carried out during its development history since 1960s and many of these researches were conducted to improve the machining efficiency, one of the main weakness of the WEDM. This paper presents the development of a WEDM system that applies a vibration-assisted process which improve the machining efficiency of the system. In addition, a developed feed-rate control system that drives the machining process at a very high rate and efficiency are also presented.
