| Abstract | We present a comparative study on three different drill bits and the factors influencing on the surface roughness in drilling Al/SiC/Graphite hybrid composite material. The surface roughness of ´coated carbide twist drill´, ´multifaceted drill´ and ´step drill´ bits were analysed. The machining parameters considered were the cutting speeds (1000 rpm, 2000 rpm, and 3000 rpm), feed rates (0.05 mm/rev 0.10 mm/rev and 0.15 mm/rev), and diameter of drill (4 mm, 8 mm and 12 mm). The analyses of the results were done using effect graphs. The results indicated that the step drill performed better than the other drills considered. |
