摘　　要：针对碳纤维复合材料(CFRP)传统钻削加工容易出现孔口缺陷的问题,本文首先从理论上分析了缺陷产生的机理。在此基础上提出了"以磨代钻、钻磨结合"的CFRP制孔加工新工艺,从加工机理上避免了孔口缺陷的产生。并研制出新型的大孔用电镀CBN钻磨复合刀具和小孔专用砂轮,进行了具体钻磨复合制孔实验。结果表明,此工艺CFRP高精度和高质量的孔加工提供了一条行之有效的加工方法。ased on the analysis of the mechanism of the defect generation in the traditional carbon fiber reinforced plastics(CFRP) drilling,a new approach of the CFRP hole machining which is mainly based on the thoughts of using grinding instead of drilling and combining these two together is proposed.Experiments were carried out on CFRP material using the tools designed and developed with new mechanism correspondingly.The results show that this method is an effective way for high-precision and high-quality CFRP hole machining.
