航空钛合金结构件具有材料和结构双重难加工特性，选择刀具时既要考虑刀具／工件在材料方面的匹配，又要关注刀具／工件在结构方面的匹配。针对目前国内航空制造业在钛合金结构件高性能加工方面对铣削刀具选择及评价的迫切需求，在已有研究的基础上设计了综合考虑航空钛合金结构件难加工特征的典型基准件模型，基于模糊数学理论分别构建了粗、精加工刀具性能模糊综合评价模型，并进行了基准件模型铣削试验，应用所构建的综合评价模型对铣削刀具性能进行综合评价与分析。研究结果表明，所构建的基准件模型和模糊综合评价模型可以准确、快捷地评价铣削刀具性能。

The machining of the titanium aircraft component is difficult to conduct in terms of material and struc-ture,so both the structural and material matches between cutting tools and work-pieces need to be considered.At present,a systematic method to evaluate and select cutting tools used in the high-performance machining of domes-tic aviation manufacturing industry is highly demanded.Aiming at this issue,a testing benchmark model is con-structed on the basis of existing researches in this paper,which takes into account the typical difficult-to-cut fea-tures of titanium aircraft components,and proposes two fuzzy comprehensive evaluation models of cutting tool per-formance of rough and finish milling on the basis of fuzzy mathematics theory.Then,by the milling experiments of the benchmark model,the proposed fuzzy comprehensive evaluation models are used to evaluate the cutting tool performance of end mills.The results show that the constructed benchmark model and the proposed fuzzy compre-hensive evaluation models can be used to assess the cutting tool performance of end mills for titanium aircraft com-ponents accurately and rapidly.
