Electric discharge machining is non conventional machining process used for machining of hard materials which cannot be machined by conventional machining process. Electric discharge machining is an electro sparking method of metal working involving an electric erosion effect. A pulse discharge occurs in a small gap between the work piece and the electrode and removes the unwanted material from the parent metal through melting and vaporizing.

Electric discharge machining is non conventional machining process used for machining of hard materials which cannot be machined by conventional machining process. Electric discharge machining is an electro sparking method of metal working involving an electric erosion effect. A pulse discharge occurs in a small gap between the work piece and the electrode and removes the unwanted material from the parent metal through melting and vaporizing. Powder-mixed electrical discharge machining is one of the latest techniques for improving material removal rate and also decreased tool wear ratio, surface roughness among other performance characteristics. How ever its utilization in the manufacturing industry is very low because many fundamental issues of this new development such as machining mechanism cost effectiveness of powder and powder concentration in the working fluid together with safety and environmental impact among other are not well understood.
