摘要:: 碳纤维增强复合材料/钛合金（CFRP/Ti）叠层材料因其优异的综合性能在航空航天领域被大量使用。在制造过程中，叠层材料通常以螺栓连接的方式组成所需的装配结构，连接孔的加工质量直接影响着叠层材料的力学性能等质量指标，因此如何提高其制孔质量及其制孔寿命被广泛关注。总结了近年来CFRP/Ti叠层材料制孔技术的研究进展，从钻削制孔和螺旋铣孔2个方面重点阐述了CFRP/Ti叠层材料的制孔过程、制孔缺陷及其形成机理以及制孔质量的影响因素；介绍了振动辅助加工技术和微量润滑（MQL）冷却方式在CFRP/Ti叠层材料制孔过程中减小切削力、降低切削温度等方面的加工优势，并对未来CFRP/Ti叠层材料制孔技术的发展方向进行了展望。

Abstract:: Carbon fiber reinforced composite/titanium alloy (CFRP/Ti) laminated materials are widely used in the aerospace sector due to their exceptional qualities. The laminated material is typically bolted together during the manufacturing process to create the necessary assembly structure. Improvements in holemaking quality and hole-making life are of great concern because they directly impact the mechanical properties of the laminated material and other quality indicators. In this paper, the development of hole-making technology for CFRP/Ti composites is reviewed both domestically and internationally. The process of making holes in CFRP/Ti laminated materials, the defects and their formation mechanism as well as the factors influencing the quality of hole making are highlighted from two aspects: drilling hole making and helical milling. The benefits of vibrationassisted machining and the minimum quantity lubrication (MQL) cooling technique are discussed, along with the potential future development path for CFRP/Ti laminated material holemaking technology.
