摘要
应用Deform-3D软件建立Johnson-Cook材料模型,采用有限元方法对42Cr Mo钢进行铣削仿真分析,研究了不同切削参数对切削仿真结果的影响,利用仿真切屑与实际切屑进行对比,验证了仿真结果的可靠性。通过仿真分析得到了在不同切削速度、切削深度下的切削力变化规律,为42Cr Mo钢切削过程的研究和切削参数选择提供理论参考。
The finite element simulation of 42 CrMo steel is carried out by using Deform-3 D software and the JohnsonCook material model is established. The influence of different cutting parameters on the cutting simulation results is analyzed. The reliability of the simulation results is also verified by comparing the simulation chip with the actual chip. Through the simulation analysis,the change rule of the cutting force under different cutting speed and cutting depth is obtained,providing a theoretical reference for the study of the cutting process and cutting parameters of 42 CrMo steel.
