| 为了在7075 T651铝合金铣削过程中控制铣削力和铣削温度，减小加工变形，笔者对不同铣削参数进行研究和优化。采用专业切削仿真软件AdvantEdge建立二维铣削仿真模型，对铣削力和铣削温度进行仿真分析，对所得到的铣削力和铣削温度的结果进行铣削实验验证；设计正交试验表获得优化的铣削参数组合，采用单因素试验法获得单一因素对铣削力和铣削温度的影响规律。结果表明：有限元仿真和实验数据误差在可接受范围内，说明了有限元模型的正确性；通过正交试验选出了控制铣削力和控制铣削温度的2组最优铣削参数组合；单因素试验的结果说明每齿进给量、铣削宽度和铣削深度的大小与铣削力的大小成正相关，而铣削力几乎不受主轴转速的影响；主轴转速、每齿进给量和铣削宽度的大小与铣削温度的高低成正相关，而铣削温度几乎不受铣削深度影响。 |

| In order to control the milling force and milling temperature during the milling process of 7075 T651 aluminum alloy and thus reduce machining deformation, different milling parameters were studied and optimized. The two dimensional milling simulation model was established by using the professional cutting simulation software AdvantEdge for the simulation analysis of the milling force and milling temperature results, and the milling experiments were carried out to verify the obtained results of the milling force and milling temperature. The orthogonal test table was designed to obtain an optimized combination of milling parameters, and the influence law of a single factor on the milling force and milling temperature was obtained by single factor test method. The resultsshow that the errors of the finite element simulation and experimental data are within the acceptable range, which illustrates the correctness of the finite element model.The two optimal milling parameter combinations for controlling milling force and controlling milling temperature were selected by orthogonal test. The results of the single factor test show that the size of the feed per tooth, the milling width and the milling depth are positively correlated with the size of the milling force, and the milling force is almost unaffected by the spindle speed.The spindle speed, the feed per tooth and the size of the milling width are positively correlated with the milling temperature, and the milling temperature is almost unaffected by the milling depth. |
