| 摘 要： | 采用二刃、三刃双锋角钻头和圆弧形钻头钻削CFRP单向板,研究钻削过程中轴向力时变曲线的特征,并探索用预测轴向力时变曲线上的关键拐点的方法来构建预测轴向力时变曲线模型。结果表明:三刃双锋角钻头的轴向力时变曲线最为稳定,钻削过程最为稳定;轴向力最大的是三刃双锋角钻头,其次是圆弧形钻头,最小的是二刃双锋角钻头,说明二刃双锋角钻头适合钻削CFRP;用预测轴向力时变曲线上的关键拐点的方法构建的轴向力时变曲线可以很好地预测双锋角钻头轴向力时变曲线。

| Abstract: | In this paper, the two-edged double point angle drill, three-edged double point angle drill and arcshaped drill were used to drill CFRP.The characteristics of drilling thrust force versus time curve are studied.And the model of predicting the time varying curve of thrust force is constructed by using the method of predicting the critical inflection point of the time varying curve.The results show that the thrust force curve of the three-edged double point angle drill is the most stable, it means that the drilling process is the most stable.The maximum thrust force is the three-edged double point angle drill, followed by the arc-shaped drill, and the minimum is the two-edged double point angle drill.So, the two-edged double point angle drill is suitable for drilling CFRP.The thrust force versus time curve constructed by the method of predicting the critical inflection point on the time varying curve of thrust force can predict the thrust force versus time curve of double point angle drill. |
