This present paper deals with the characteristric of wire vibration of wire EDM by laser beam measurement. In order to mesure frequency of the wire vibration, we developed laser beam measurement using Si-photo diode. There are also presented the results of the experimental researches. The frequency of the wire vibration is varied with feed rate, wire speed, voltage and offtime. Among these parameters, wire speed is very much influenced the frequency. It is possible that the optimum condition is predicted by the developed laser beam measurement.
