摘　　要：CFRP/钛合金叠层结构材料具有轻质高强、能承受极端热力载荷等优点,广泛应用于航天航空关键承重部件的制造。在钻削加工CFRP/钛合金叠层结构时,由于CFRP相和钛合金相具有不同的性能特征,导致刀具的磨损行为迥异,从而对CFRP/钛合金叠层结构的钻孔精度及孔壁质量造成严重影响。为此,探究CFRP/钛合金叠层结构钻削时的刀具作用机理和开发理想的加工刀具,对确保CFRP/钛合金叠层结构高品质制孔具有重要意义。针对CFRP/钛合金叠层结构钻削时存在的刀具磨损快、制孔质量差等问题,从刀具基体材料、刀具涂层材料和刀具结构三个方面,对CFRP/钛合金叠层结构制孔损伤控制中的刀具开发与应用现状进行了综述,并对相关研究中存在的不足和研究趋势进行了分析和探讨。CFRP/titanium alloy laminated structures are widely used in manufacturing the key load-bearing components in aerospace industry because of their high strength,low density and the ability to withstand extreme thermal loads.Due to the different material characteristics of CFRP and titanium alloy phases,the wear behavior of tools is very different when drilling,thus causing such defects as poor accuracy and serious wall damage of holes.Hence,investigating the mechanism of drilling the CFRP/titanium alloy stacks structure and developing an ideal tool have become an urgent need to ensure high-quality holes.In this paper,concerning the problems of fast tool wear and poor hole quality in drilling the stacks structure,the development and application status of drilling tools for CFRP/titanium alloy stacks structure are summarized from the aspects of substrate,coating and tool structure,and the shortcomings and research trends in the related researches are also discussed.
