有限元法是对金属切削机理进行理论研究的有效方法.研究了金属切削模型、本构模型、摩擦模型、切屑分离等有限元模拟所必需的关键技术.采用ABAQUS软件对AISI4340钢的正交切削过程进行模拟,分析了其应力应变、温度、切削力,证明所建立的有限元模型是合理的.%Finite element analysis is an effective method which can be used to study metal machining mechanism. This paper makes a study of several key finite element techniques such as cutting model, constitutive model, friction model and chip separation and simulates the orthogonal cutting process of AISI4340 alloy material by the use of finite element software ABAQUS and then analyzes its stress, strain, temperature and cutting force.lt proves that the constructed finite element model is reasonable.
