Abstract

WEDM (Wire Cut Electrical Discharge Machining) is a kind of spark cutting machining processes by using the linear movable electrode (known electrode wire).With the development of science and technology and the emergence of a large number of new materials, EDM wire cutting start to face new challenges. The characteristics of these new materials such as multiphase materials processing, electrical conductivity, thermal conductivity inhomogeneity, as well as processing of large thickness of the workpiece result in low efficiency of EDM wire cutting and high frequent wire broken. Recent years, seldom research on the introduction of ultrasonic vibration into medium-speed EDM wire cutting has been done. This article aimed to analyze the influence on the cutting efficiency and workpice suface roughness by using self-made ultraconic assisted appratus on Medium-speed EDM. The results showed that ultrasonic vibration can improve the efficiency of wire electric discharge machining , and it can alao reduce the surface roughness Ra value of the workpiece. What's more, the cutting speed is higher when the direction of ultrasonic vibration and cutting direction is vertical rather than parallel.
