Introduction Wire Electrical Discharge Machining (WEDM) is an indispensable nontraditional machining process, capable of producing complex two and three-dimensional shapes with good accuracy and precision to satisfy the present day requirements of the manufacturing industries This method is used in the aerospace, automotive, die and tool industries and virtually in all the areas of conductive material machining regardless of their hardness or toughness. By using this method we are optimizing the various output parameter by machining on EN-27 material, to form good quality product

Sr.No Name of author Title of paper Work carried out 3 Tushar Saini , Khushdeep Goyal & Deepak Bhandari . Multi-response optimization of WEDM parameters on machining 16MnCr5 alloy steel using Taguchi technique Pulse on time is the most significant parameter and thereafter order of significance being pulse off time and peak current in MRR. MRR increases with increases in pulse on time. Since the energy released per spark increases with increase in pulse ontime,hencehighertimeforeachsparkisprovidedleading to more material removal rate. 4 PrashantSinha , Rajeev Kumar , G.K.Singh & DainThomas Optimization of Wire EDM of AISI D3 Tool Steel using Orthogonal Array with Principal Component Analysis In single objective optimization using Taguchi method, servo voltage and pulse on time and peak current are the significant factors for MRR,while peak current and servo voltage are the significant for SR. Multiple quality characteristics (MQC) has found improved by using hybrid approach of Taguchi method and principle component analysis(PCA) as compared to initial parameter setting.

The meaning of EN in the EN STEELS is 'European standard' or ' Euronorm ’ that specifies the requirements for a product or process. For each steel standard the first two letters EN denote that it is a European Steel standard, the number after that is the standard number. EN Steel is an alloy of iron with typically a few percent of carbon to improve its strength and fracture resistance compared to iron,many other additional elements may be present or added.

In this project we have considered EN-27 material, because of its good mechanical properties and also have various applications. It also have a very good advantages as it has high hardness and toughness, hence it can be also use for making tools and dies. We are going to consider the various input and output parameters for manufacturing a good quality product of EN-27 material by using Taguchi Method for optimizing the various output parameters like MRR, Surface finishing and surface roughness. 22-Sep-20 CONCLUSION
