Study on LSWEDM with Ultrasonic Vibration of the Wire

A research has made about the effects of highvibration of wire on the machining performance in LSWEDM assisted with ultrasonic vibration in the paper. The mathematical model to describe the vibrationstate of wire under the action of ultrasonic vibration and discharge force has been established, through which computer simulation has been made in the paper to study the vibration of wire. It was found by experimental results that the machining condition is improved by the wire-tool ultrasonic vibration, high machining rate and good machined surface quality can be obtained,and the breakage of wire can be decreased.
