MULTI RESPONSE OPTIMIZATION IN TURNING OF AISI 8620 ALLOYSTEEL WITH PVD TOOL USING TAUGHI AND ANOVA AND GREY RELATION ANALYSISCOMPARITIVE STUDY

A.Rajasekhar , R.K.Suresh

The challenge of modern machining industries in mainly focused on the achievement of high quality, in terms of work piece dimensional accuracy, surface finish, high production rate, less ware on the cutting tool, economy of machining in terms of cost saving and increase the performance of the product with reduce environmental impact. Surface roughness plays an important role in many areas and is a factor of great importance in the evaluation of machining accuracy and to have high productivity MRR plays a vital role. Optimization of multi criteria problems is a great need of manufactures to produce precision Parts with low cost.Optimization of multi performance characteristics is more complex compared to optimization of single performance characteristics. Various turning parameters, such as spindle speed, feed related depth of cut were considered. For the purpose of experimentation L9 orthogonal array is used as per Taguchi design of experiments.
