| 摘 要： | 采用自主磨制的阶梯钻对碳纤维复合材料/钛合金叠层板进行钻削磨损试验,并与普通麻花钻进行对比,分析了阶梯钻刀具磨损过程。实验结果表明:阶梯钻主要磨损区域为横刃、第一后刀面和第二后刀面,其中第二后刀面磨损最为严重,相比普通麻花钻,阶梯钻产生的钻削力更小,阶梯钻刀具寿命远远高于普通麻花钻。

| Abstract: | The wear drilling experiment of the CFRP/TC4 was carried out by using the self-grinding tool and compared with the ordinary twist drill. The wear process of stepped drill was analyzed. The experimental results show that the main wear area of the stepped drill is chisel edge, the first flank face and the second flank face, and the second flank wear is the most serious. The drilling force of the stepped drill is smaller than that of ordinary twist drill.The tool life of step drill is much higher than ordinary twist drill. |
