对三种不同钻头钻削Al/SiC/石墨混杂复合材料的表面粗糙度及其影响因素进行了对比研究。分析了涂层硬质合金麻花钻、多面钻和阶梯钻钻头的表面粗糙度。所考虑的加工参数为切削速度（1000 rpm、2000 rpm和3000 rpm）、进给速率（0.05 mm/rev、0.10 mm/rev和0.15 mm/rev）和钻头直径（4 mm、8 mm和12 mm）。使用效应图对结果进行分析。结果表明，阶梯钻的性能优于其他考虑的钻。
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.
