Study on the Flushing in EDM

Self Flushing Method

Abstract

This paper deals with a new flushing method for EDM diesinking. A self flushing (SF) system which is based on the pumping effect by a special movement of the electrode is proposed to improve the flushing efficiency. A prototype system is developed and tested on its effectiveness. The result shows the superiority of this method to conventional lifting method especially in the stability of machining and consequently in the productivity. This SF method can easily be applied on a machine which supports a planetary movements.
