多层复合涂层刀具切削过程的三维有限元仿真

3-dimensional finite element simulation on the cutting process of multi-layer coating tools

利用DEFORM-3D软件,对多层复合涂层刀具的切削过程进行三维有限元仿真研究,获得了切削过程中的切削温度、切削力和刀具应力等参数,并进行了相关的切削实验对比。实验结果表明,仿真所得的切削温度和切削力结果与实验结果能够较好地吻合,仿真所得的刀具应力结果能够较好地说明涂层的破坏。该仿真方法可以作为研究多层涂层刀具失效机理的有效方法,

3-dimensional finite element simulations were performed on the cutting process of multi-layer coating tools using DEFORM-3D software. Parameters including cutting temperature, cutting force and tool stress were obtained and compared with the results of corresponding cutting experiments. The simulating results of cutting temperature and force are consistent with the experi- ment results, and the damage of the coating layers could be explained by the results of tool stress. It is shown that this simulation method could be used effectively in the research on the invalidation of multi-layer coating tools.
