摘　　要：铝锂合金作为一种先进轻量化材料,具有相对较低的密度、较高的比强度和比刚度以及较好的疲劳性能,在航空航天领域应用广泛。但在铝锂合金切削加工过程中易于出现黏附磨损,从而引起加工质量差、使用性能下降等一系列问题。因此,国内外学者针对铝锂合金切削加工进行了相关研究。对近年来在铝锂合金切削加工试验方面的研究进展进行了总结,重点分析了切削力、切削温度、加工表面质量、刀具磨损以及参数优化方面的研究成果,指出了目前存在的问题以及今后的发展方向,对铝锂合金切削加工技术的发展具有一定的促进作用。As an advanced lightweight material, Al–Li alloy has relatively low density, high specific strength and stiffness and good fatigue properties. It is widely used in the field of aerospace. However, adhesion wear is easy to occur in the cutting of Al–Li alloy, which leads to a series of problems, such as poor machining quality and service performance.Therefore, domestic and foreign scholars have carried out relevant research on the machining of Al–Li alloy. This paper summarizes the research on the cutting experiments of Al–Li alloy in recent years, focuses on the research results of cutting force, cutting temperature, machined surface quality, tool wear and parameter optimization. The existing problems and future development direction are pointed out. It can promote the development of Al–Li alloy cutting technology.
