Abstract: Nowadays, the Fiber Reinforced Polymer (FRP) has replaced many of the mechanical components and this composite industry is experiencing significant growth. FRP’s also have replaced several traditional materials used in building, sporting equipment/appliances, automotive/aircraft parts, boat and canoe hulls, and bodies for recreational vehicles. The composites in general, offer many advantages over traditional materials: important among these are high strength to weight ratio, light weight, flexible design, parts consolidation, dimensional stability, corrosion resistance and low tooling costs. Since the composites are anisotropic in nature, machining them is a complex process especially with reference to drilling and milling. Therefore, during the dry drilling operation on composites, drilling induced damage drastically affects the performance of the drill tool. So, the present investigation is an attempt to study the effect of the drill process parameters like the spindle speed (1000,

Abstract: Functionally graded materials (FGM) are advanced class of engineering materials in which location specific properties are made use in components of specific applications in a more economical and performance efficient ways. Functionally graded metal matrix composites (FGMMC) have graded distribution of reinforcements; whose volume fraction varies continuously in a component leading to a tailored microstructure with continuously changing properties. AA 6061 FGMMC with 10 wt% silicon carbide particles (SiCp), of 23 µm sizes, reinforced composite is processed by liquid metal stir casting method followed by vertical centrifugal casting to obtain the FGM ring. The SiCp due to their higher density than the matrix diffuse towards the outer periphery giving a graded structure. While the porosities, impurities and agglomerates with lower densities accumulate towards the inner periphery and can be removed by machining. Microscopic image analysis shows higher volume percentage of SiC near the oute
