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.
