摘要
根据金属材料切削加工有限元仿真建模理论建立了基于Deform-3D的金属薄壁零件切削加工有限元模型。通过仿真计算获取切屑形成过程、切削力变化曲线、切削区域应力分布云图、应变分布云图、切削温度场分布云图,并得出结论:仿真实验获得的切削过程参数值符合金属切削理论,仿真研究可行。借助仿真研究可在实际加工前预测切削过程参数值,对优化切削加工过程和提高薄壁零件加工质量具有重要意义。
The finite element simulation modeling theory of metal material machining is analyzed. The finite element model of metal thin-walled parts based on Deform-3D is established. Through this simulation,the chip formation process,the cutting force curve, the stress distribution of the cutting region, the strain distribution and the distribution of the cutting temperature field are calculated, The parameters of cutting process obtained by simulation experiments are inaceordance with the classical theory of metal cutting ,which proves the feasibility of the simulation study. The simulation study can pre- dict the parameters of cutting process before actual machining, and it has important significance to optimize the machining process and improve the machining quality of thin - wailed parts.
