“OPTIMIZATION OF SURFACE QUALITY FOR TURNING OPERATION USING GREY BASED TAGUCHI TECHNIQUE”
Mechanical Engineering Department, J.H.Desai Polytechnic, Palsana, India
ABSTRACT
Surface finish is an important quality characteristic of any manufactured part. Machining process is often employed to improve the surface finish. In this study, different experiments of turning operation will be performed on mild steel samples by HSS SPCT using different values of cutting parameters like cutting speed, depth of cut and feed rate using design of experiments on CNC lathe. Eighteen such experiments will be performed and the surface finish data will be recorded as per L18 orthogonal array. This data will be used to calculate the grey relational coefficients and then the grey relational grade which are then used to calculate S/N ratios. The values of S/N ratios are used predict the optimal parameters for turning operation. Confirmation tests will be used to confirm the predicted results.
