Preference Number Based Taguchi-Utility Method for the Optimization of Multiple Responses

Asst.prof. Ch. Maheswara Rao, Prof. K. Venkata Subbaiah

Abstract


In the present study a multi-objective optimization approach called taguchi-utility method is employed to find the optimal process parameters in turning of AA7075 material. Cutting speed, feed and depth of cut were taken as the process parameters at three different levels. Taguchi’s standard L9 (3^3) orthogonal array has been followed for conducting the experiments. Utility method converts the multi-responses into a single equivalent response in terms of utility index. ANOVA is employed to find the contribution of the process parameters and it is found that depth of cut has the high influence on the overall utility index.
