摘要

采用有限元法对30CrMnSi不锈钢正交切削过程进行了数值模拟。首先，根据材料的物理特性，建立了工件和刀具的有限元模型;其次，通过不锈钢的经验切削参数，建立了正交切削实验台。最后通过仿真得到了模型的应力场、温度场和切削力。仿真结果表明，切削力在切削过程中由零开始迅速增大，然后减小，最后在一定范围内变化。此外，在低速切削情况下，切削深度对应力场、温度场和切削力有重要影响。为30CrMnSi不锈钢的实际加工提供参考。

Finite Element Simulation and Analysis of Stainless Steel30CrMnSi Orthogonal Cutting

Simulation of stainless steel 30CrMnSi orthogonal cutting is carried out employing finite element method. Firstly, finite element model of workpiece and cutting tool were established according to physical properties of materials. Secondly, orthogonal cutting experiment table was also built through empirical cutting parameters of stainless steel. Finally, stress field, temperature field of model and cutting force were obtained from simulation. The simulation results show that the cutting force increases rapidly from zero and then decreases, finally changes in a certain range in the process of cutting. In addition, depth of cut plays a major influence on stress field, temperature field and cutting force in the circumstance of low speed cutting. It provides reference for the actual machining of stainless steel 30CrMnSi.
