Now a days,the production of complicated shapes of different components with high accuracy is very difficult and take much time by conventional machining process. To get-rid of the one non conventional machining process which is used very widely in EDM, it is necessary to optimize the process parameters like pulse on-time (TON ),pulse off-time(TOFF),discharge current(I),voltage(V) for maximization of material removal rate (MRR),minimum tool wear rate(TWR), minimum surface area(Ra) for various materials like aluminium alloy 6082.The aluminium alloy 6082 is machined using graphite electrode on spark erosion machine.basically EDM is well-established non-conventional machining process used for manufacturing geometrically complex or hard and electrically conductive material parts that are extremely difficult –to- cut by other conventional machining processes.erosion pulse discharge occurs in small gap between work piece and the electrode ,this removes the unwanted material from the parent metal through melting and vaporizing in the presence of dielectric fluid.the presence of metal particles in dielectric fluid diverts its properties,which reduces the insulating strength of the dielectric fluid and increases the spark gap between work piece and electrode.as a result,the process becomes more stable and surface finish increases.the EDM process is mainly used for making dies ,mould,parts of aerospace ,automotive industry and surgical components etc..The process parameters are optimized for maximum material removal rate(MRR),tool wear rate(TWR) and surface roughness(Ra) based on experimental results by using .DOE and optimization for best machining can be done by response surface methodology.
