- Abstract
In the present work, A356 aluminum alloy with 5 wt. % SiC reinforcement was made-up by electromagnetic stir casting process. The main objective of this work is to find out the influence of Polycrystalline Diamond (PCD-10) tool geometry on the surface roughness, during turning operation of metal matrix composite (A356/5wt.% SiC). Box-Behnken Design technique was preferred to observe the effect of tool geometry on the surface roughness. The results show that when rake angle increases, surface roughness decreases, but reverse phenomena is observed when approach angle and nose radius increase, surface roughness also increases. To minimize the surface roughness (Predicted 3.732 ìm) and flank wear (0.05 mm), optimum values of rake angle (-3 degree), approach angle (50 degree) and nose radius (0.4 mm) has been obtained during machining.
