Multi Characteristics Optimization of Treated Drill Tool in Drilling Operation Key Process Parameter Using TOPSIS and ANOVA Technique 2019-28-0055

To survive in the present global competitive world, the manufacturing sectors have been making use of various tools to achieve the high quality products at a comparatively cheaper price. Appropriate cutting set up must be used to further better the machinability of a work piece material. A longer life of the tools and equipments are important factors in any industry. Since the inception of the machine tool industry, cutting tool life and tool wear remain a subject of deep interest to study its failure and improvement. The present study finds out the optimum cutting results in drilling of AM60 magnesium alloy using different cryogenically treated cutting inserts. The Utility concept coupled with Taguchi with Multi response approach (TOPSIS) was employed. According to Analysis of variance (ANOVA) results, the feed was the major dominating factor followed by the cutting speed. This work deals with optimization approaches for the determination of the optimum process parameters by cryogenically treated drill HSS tools which minimizes surface roughness, torque, tool life, entry burr and tool cost, and maximizes material removal rate in a drilling operation of high-speed steel. Spindle speed, feed, and three different combinations of treated drill bits are taken as the input process parameters for this study. The experimental results obtained from design of experiment are optimized using TOPSIS and ANOVA technique to determine the optimized values.
