Abstract

In recent days, the Fiber Reinforced Composites have replaced many of the engineering components and the composite material manufacturing area is experiencing substantial growth. FRC’s also have replaced materials used in the civil construction area, sporting goods, automobile and aircraft parts, and boat and ship hulls. The composites in general, offer many advantages over homogenous materials like high strength to weight ratio, less weight, structural and dimensional stability, corrosion and wear resistance. Because of the anisotropy in nature, machining composite materials with drilling and milling is a complex process. Especially for composites, these operations were found to be costly affair as the cutting tool wears out quickly as it comes in contact with the hard resin and abrasive reinforcement material during machining. Thus the quality of the drilled hole in composites depends on the performance of the drill tool. The performance of the drill depends on the magnitude of respective process parameters. Hence the present investigation focusses on the study of effect of the machining parameters such as spindle speed (1200, 1500 and 1800 rpm), feed rate (0.1, 0.2 and 0.3 mm/rev), drill diameter (6, 8 and 10mm) on HSS drill tool flank wear in the drilling of Glass Fiber Reinforced Polyester (GFRP) composites. The present work also aims to optimize the machining parameters in drilling minimize the flank tool wear. The experiment is designed using full factorial design of experiments. Measure of land width was used to assess the Flank wear of HSS drill. To optimize the drill flank wear, the process parameters are optimized applying Response Surface Methodology (RSM). Mathematical model was generated by through regression analysis by developing a Regression equation for flank wear of HSS drill.
