In this study, cotton/bamboo woven fabric reinforced composite has been subjected to drilling operation and thrust force is analysed for different combination of feed rate, cutting speed and drill geomentry. Box-Behnken experimental design is used to optimize the cutting parameters along with the input parameters, such as drill- bit geomentry, spindle speed and rate of feed. Further, a drill with standard twist is used for drilling operation. The results show that with the increase in thrust force, feed rate increases and cutting speed experiences decrease when drill diameter is increased. The SEM analysis is also done to reveal about various damages, like fibre pullout, peel off, uncut fibres and voids.

利用Box-Behnken方法分析竹混纺纤维增强复合材料在棉花钻孔中的推力

在这项研究中，棉/竹织物增强复合材料已进行了钻孔操作，并分析了进给速度，切削速度和钻头几何形状的不同组合的推力。Box-Behnken实验设计用于优化切削参数以及输入参数，例如钻头几何形状，主轴转速和进给速度。此外，具有标准扭转的钻头用于钻孔操作。结果表明，随着推力的增加，钻头直径增加时，进给速率增加，切削速度降低。还进行了SEM分析以揭示各种损坏，例如纤维拉出，剥离，未切割的纤维和空隙。
