This paper observes the WEDMed surface of Carbon Fiber Reinforced Plastics (CFRP) in order to evaluate the influence of heat of electrical discharge on CFRP. WEDM of CFRP was carried out parallel to or perpendicular to fibers orientation, and obtained surfaces were observed using scanning electron microscope. It is found for the case of discharge current 45A that plastics around fibers is removed on the WEDMed surface by the heat of the electrical discharge, and carbon fibers are bare on the surface. On the other hand, for the case of discharge current 8A, plastics are remained around the fibers. These results indicate that the plastics removal can be avoided when small discharge current condition is selected. It is also found that the lack of the carbon fiber does not occur in wire EDM process whereas it occurs in cutting process.
