| 摘 要： | 为有效解决腔薄壁件的加工变形问题,本文采用三维有限元分析方法,模拟了在给定的装夹条件下,不同的铣削走刀路径对航空薄壁框类零件加工变形精度的影响.仿真结果表明,在保证其他加工条件不变,只改变走刀路径的情况下,零件加工变形存在较大的不同.其中,采用从外向内的加工路径进行铣削加工时产生的变形较其他3种情况要小.最后通过铣削加工实验验证了模拟结果的正确性.

| Abstract: | To resolve the deformation problem for thin-walled aero-parts in the actual production, this paper simulates the effect of the tool-path on the machining accuracy of the thin-walled frame. The frame is shaped in the part milling under a given clamping condition by using the three-dimensional finite element method (FEM). Result shows that the sidewall deformation has a big difference if only the tool-path changes. When the tool-path from the outside to the inside is used, the machining deformation is smaller than another three kinds of toolpaths. Simulation results are compared with experimental data, and the correctness of the simulation is verified.Reasonable processing paths can be found by FEM. |
