摘要：随着航空航天和汽车工业的发展，铝合金因其优良的性能得到了广泛应用，但铝合金铣削时出现的加工变形问题日益突出。铣削过程中产生的残余应力是导致加工变形的主要原因，相较于传统试验方法，有限元模拟仿真研究残余应力具有省时省力、节约成本的优点，更能获知应力场、应变场、温度场等重要信息，因此采用有限元技术对切削加工进行数值仿真将是未来研究铝合金结构件变形问题的大趋势。本文阐述了近年来国内外有限元模拟铣削过程的研究进展，总结了不同条件下对铣削铝合金残余应力的分析及研究成果。

Abstract:With the development of aerospace and automobile industries，aluminum alloys have been widely used due to their excellent properties.However，the problem of machining deformation occurring during the milling of aluminum alloys has become increasingly prominent.The residual stress generated during the milling process is the main cause of the machining deformation.Compared with the traditional experimental method，the finite element simulation study has the advantages of saving time and labor，saving cost，and knowing the important information of stress field，strain field and temperature field.So the use of finite element technology to numerically simulate the cutting process will be a major trend in the study of deformation of aluminum alloy structural parts in the next few decades.In this paper，the research progress of finite element simulation milling process at home and abroad is expounded in recent years，and the analysis and research results of milling residual stress of aluminum alloy under different conditions are expounded.
