摘要：对碳纤维/聚酰亚胺和碳纤维/环氧树脂两种复合材料的钻削加工性能进行了对比研究，分析了不同主轴转速和进给量条件下碳纤维增强复合材料加工过程中轴向力和钻削温度的变化规律，并对钻削后的制孔质量（如出口形貌与撕裂程度）进行了研究。结果表明：碳纤维/环氧树脂相比碳纤维/聚酰亚胺的钻削加工性能更差，主轴转速和进给量对两种复合材料的制孔质量有显著影响。

Abstract:The drilling machinability of carbon/PI and carbon/epoxy composites is compared，and the variations of the thrust forces and machining temperatures in terms of different spindle speeds and the feed rates are analyzed during the composite drilling process.Additionally，the hole quality (such as the exit hole morphologies and tearing extents) is studied.The results indicate that the carbon/epoxy composites show a much poorer machinability than the carbon/PI composites，and both the spindle speed and the feed rate have a significant effect on the hole quality of the two composite materials.
