Abstract
Of late years, the performance of Wire EDM has improvid and become almost equal to that of Grinding. In order to improve the performance of Wire EDM moreover, it is necessary to investigate the wire electrode throughly. There is no paper, however, which deals with the characteristics of the wire electrode in Wire EDM. This study is for the purpose of developing a new wire electrode which has good performance in Wire EDM. In this paper, the working characteristics of various ally wire electrodes were examined. And about the wire electrodes which have good performance, the cause of the superiority was searched.
