Investigation of the Impact of Nose Radius on the Multiple Performance Characteristics

Ch. Maheswara Rao, K. Venkata Subbaiah


The present work is to study the effect or influence of the turning process variables on the multiple responses. Experiments are planned as per the L16 orthogonal array by taking the speed, feed, depth of cut and the nose radius as the process variables. The multiple responses of material removal rate and surface roughness are optimized concurrently using TOPSIS method. From the results, the optimal combination of process variables is found at speed of 2500 rpm, feed of 0.1 mm/rev, depth of cut of 1.2 mm and nose radius of 0.4 mm. ANOVA results noticed that the nose radius has the highest influence on the multiple response.
