Abstract

Abstract: This paper presents an investigation into feasibility of using Electro-Discharge Machining(EDM)as a means of machining carbon fibre composite material. Basically, it is found that the EDM process can easily machine the composite material with small current. The presence of non-conducting fibre in the composite materisl does not affect the machining efficiency. The non-condudcting fibres turn into conducting fibres due to carbonization during the ionization stage.

Key words: carbon fibre, composite material, electrical discharge machining
