Ceramic materials which have high hardness and brittleness cannot be machined by traditional machining process because of their low efficiency and feasibility. But in non-traditional machining process, it overcomes these limitations proving it to be very useful in manufacturing process. In this review paper we are discussing about electrical discharge machining (EDM) process on Al2O3 and Si3N4 ceramic materials which are machine able. EDM parameters like material removal rate (MRR), tool wear rate (TWR), surface finish are discussed. EDM is very much suitable for ceramic materials because of its high surface finish, accuracy and efficiency.
