| 摘 要： | 采用硬质合金麻花钻对碳纤维复合材料-钛合金叠层板进行钻削试验,分析了钛合金层加工参数对刀具磨损的影响和刀具磨损机制。刀具磨损对孔入口处最大撕裂长度的影响。结果表明:磨损的主要区域是横刃和后刀面,前刀面磨损不明显。钛合金层的低转速和低进给量可以降低刀具磨损;此外随着钻孔数的增加,钛合金层转速越低、进给量越大碳纤维复合材料孔入口处孔质量更好。

| Abstract: | Through drilling on carbon fiber reinforced polymer(CFRP)/titanium alloy(Ti6Al4V) stacks with the carbide twist drill, this paper studied tool wear mechanisms, the influence of titanium layer processing parameters for tool wear and effects of cutting tool wear on the largest tear length of hole entrance.The results showed that the main area of wear is the horizontal and the flank,and the wear of the rake face is not obvious. When drilling the titanium alloy layer,low speed and low feed rate can be used to reduced tool wear.With the increase of the number of holes,the hole entrance of the titanium alloy layer is more stable. |
