SELECTION OF BEST METAS FOR TOOL AND DIE STEEL

Abstract

The main purpose of this study is related to selection the best metals for tool and die steel applications. The investigation work is performed on two metals (H-13) and (D-3) metal. C.N.C electrical discharge machining is used to machining on metals with the help of copper electrode. The E.D.M machine process parameters current, pulse on time, pulse off time values are varied to performing the experiments. The responses of the experiments are measured in the form of M.R.R and S.R. The box- Beheken design of response surface methodology is used to generate the design of experiment. The experiment result is reveals that current is most important factors which affect on S.R and M.R.R for metals.
