Multi-Response Optimization of Process Parameters Based On MRSN for D2 Steel Using WEDM Process with Plain Brass Wire and Zinc Coated Brass Wire
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 9
Abstract
Wire Electrical Discharge Machining plays an important role in precision machining. The material removal rate, higher the best and surface finish, lower the best, are mostly required as output response. But it is a well known fact that both can’t be achieved simultaneously. In this study multi response signal noise (MRSN) method is used to optimize different process parameters for material removal rate surface roughness using different weightage for both. Hardened D2 steel is used as workpiece because of its high application in industries. The L18 mixed orthogonal array is used to perform experiments and ANOVA is used to find contribution and significance of different process parameters. Plain brass wire and zinc coated wire are used to perform experiments. Confirmatory experiments are performed at optimum levels and percentage error or change is calculated to draw conclusions about design of research.
