Improvement of EDM Efficiency by Supplying Oxygen Gas into Gap

This paper describes a new method of EDM which is supplied with oxygen gas into the discharge gap, when a water based dielectric is used. It is found that the stock removal rate is increased due to the enlarged volume of discharged crater and more frequent occurence of discharge. During the analysis...

Summary:This paper describes a new method of EDM which is supplied with oxygen gas into the discharge gap, when a water based dielectric is used. It is found that the stock removal rate is increased due to the enlarged volume of discharged crater and more frequent occurence of discharge. During the analysis and discussions, attentions are paid on the heat and force caused by the activated chemical reactions of oxygen.
