摘　　要：切削加工仿真是计算机仿真技术在机械制造业的重要应用领域之一。该技术对减少制造成本、缩短产品制造周期和提高产品质量意义重大。仿真模型的建立是实现切削加工仿真的关键环节,也是评价仿真系统优劣的重要指标之一。目前存在的切削加工仿真建模方法主要有三种:解析法、有限元法和分子动力学法。重点介绍了上述建模方法的实现原理和发展现状,并对其优缺点和适用范围加以评述。在此基础上,对切削加工仿真建模技术发展趋势做了进一步探讨。Machining simulation is one of the important applications of computer simulation in modern mechanical manufacturing industry. It is of great significance to produce quality parts more quickly and economically. Modeling is the key aspect of machining simulation, and it is also one of the vital criteria to the simulation system evaluating. Up to now, there are three existed modeling methods to machining simulation mainly, which are analytical modeling method, finite element modeling method and molecular dynamics modeling method. The principle and status of those methods are introduced in detail, and their advantages and current limitations are discussed as well. Then, the developing trend of modeling technology to machining simulation is presented.
