摘　　要：以正交铺设的Kevlar层合板为对象,采用烧结金刚石钻头对其孔加工进行试验研究。针对Kevlar复合材料的各种加工缺陷,设计了预压应力工艺装置,在此工艺条件下,可以采用水进行冷却,其加工质量良好。通过试验分析了钻头参数及加工工艺参数对加工效率的影响,为烧结金刚石钻头在该加工领域的应用提供了参考。研究成果为Kevlar复合材料的孔加工技术提供了一种新的方法。With sintered diamond bits, experiments on hole drilling of orthogonal Kevlar laminate were carried out. Considering the various defects in the drilling process of Kevlar laminate, the process equipment with compressive prestress was presented. On condition that the comt）ressive prestress is effective, pure water can be used as the cutting coolant, and the quality of hole drilling is satisfactory. The influence of bit parameters and technological parameters on machining efficiency was studied, which is a guide to application. The research provides a new approach for hole drilling of Kevlar laminate.
