摘　　要：CFRP/Ti叠层结构在一体化制孔的过程中易出现复合材料分层、撕裂、灼伤和孔出口毛刺等制孔缺陷。本文基于低频振动辅助钻削技术,进行工艺实验,经过二次优化后得到最优加工参数。实验结果表明,在转速400 r/min、进给量12 mm/min、振幅75μm与转速500 r/min、进给量21 mm/min、振幅75μm两组加工参数下的制孔质量较好,使用较高转速和较大进给量能够提高加工效率。The CFRP/Ti laminate structure is prone to delamination,tearing,burns,hole exit burrs and other hole making defects during the integrated driling process.Based on low-frequency vibration assisted drilling technology,after the second optimization,the optimal processing parameters are obtained in this article.Experimental results show:the hole-making quality is better under these two sets of processing parameters of speed of 400 r/min,feed of 12 mm/min,amplitude of 75μm and speed of 500 r/min,feed of 21 mm/min,and amplitude 75μm.Using high speed and large feed can improve processing efficiency.
