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, offermany advantages over homogenous materials like high strength to weight ratio, less weight, flexibility in design, structural and dimensional stability, corrosion and wear resistance along with low tooling cost. Because of the anisotropy in nature, machining composite materials is a complex process especially operations involved in in drilling and milling. Therefore, dry drilling operation on composite materials affects the performance of the drill tool. Hence in the present investigation, the effect of the process parameters such as spindle speed (1000, 1200 and 1500 rpm), feed rate (0.1, 0.2 and 0.3 mm/rev), drill diameter (6, 8 and 10mm) and orientation of the reinforced glass fibers (Random,Random+Stitched and Random+Rowings) on the tool wear of the HSS drill bit is studied. The experiment is designed using Taguchi‟s method. Measure of Signal-to-Noise (S/N) ratio was used to assess the effect of parameters on response. Relative effect of factors is assessed using ANOVA. The process parameters are optimized to reduce the tool wear.
