Cutting Force Analysis in Drilling of Al6061/Mica Particulate Composite

Article Preview

Abstract:

Metal Matrix Composites are being widely used in numerous applications like aerospace, Automobiles, Consumer goods etc. However, machining of these composites are being faced a lot of drawbacks in terms of increases in thrust force, machined surface roughness and tool wear etc. due to reinforcements of high hardness. In this paper, thrust forces in drilling of Al6061/mica composites with 1 and 3 weight% are recorded from Dynamometer for analysis. Cutting tool material of Tungsten carbide coated with TiAlN with 8 mm diameter was used. Al 6061/Micap composites were scrutinized on cast surface with the help of optical microscope. Also, Thrust force was analysed for different Cutting Speed and feed. It can be concluded that, as weight% of mica increases Thrust forces were decreased.
