摘要

针对钛合金 /CFRP 叠层材料在传统加工中的制孔缺陷和刀具寿命低的问题，进行了低频振动制孔参数优化试验研究，提高了制孔质量和刀具寿命。低频振动制孔的参数优化试验分两步进行，首先开展不同的切削参数组合的全面试验，进行参数的大范围寻优，确定一组优化参数，然后在试验确定的最优参数值附近的范围内进行再次寻优。在最优参数工况条件下，将低频振动制孔与传统非振动制孔进行对比，验证优化参数的有效性。结果表明，对比低频振动制孔与传统非振动制孔刀具的磨损程度，前者对刀具使用寿命有提升作用。在最优参数工况条件下，低频振动制孔可以减小切屑尺寸、提高制孔质量、延长刀具寿命。

Abstract

During drilling of Ti/CFRP stacks in traditional ways

damages and tool wear occur frequently. In this study

the parameters of low-frequency vibration (LFV) drilling were optimized to improve the drilling quality and tool life. The parameters of LFV drilling were optimized in two steps. Firstly

a group of optimal parameters were obtained by combing of different cutting parameters in orthogonal experiments. Then a small range of drilling parameters near the optimal parameters were selected and optimized again according to extra orthogonal experiments. By using the final optimized parameters

the validity of optimal parameters was verified by comparing of the traditional drilling results and the LFV drilling results. The results showed that the tool wear was improved distinctly when drilling with LFV method. Also

it helps to decrease cutting chip size while increasing hole quality and elongating tool life.
