Study on Drilling of Al/Al₂O₃/Gr Hybrid Particulate Composites

Abstract:

This study presents an experimental investigation on the effects of cutting speed, feed and percentage of alumina particle on the burr height in drilling of Al 6063 reinforced with Al₂O₃ and Gr particles using solid carbide twist drills of 6 mm diameter. Taguchi method with three factors at three levels is employed to analyze the drilling characteristics of these composites. For all cutting conditions, Al 6063/6%Al₂O₃/1%Gr composite has lower burr height values than other fabricated composites. The results revealed that exit hole burr height are greatly influenced by the feed rate rather than the speed for all the samples of hybrid composites.
