    摘要:

    为了研究GH536高温合金的铣削力来指导生产,利用DEFORM-3D对GH536的铣削过程进行了建模和仿真;设计铣削正交仿真方案,对仿真结果进行极差分析。结果表明:铣削深度、铣削宽度和每齿进给量对Fx、FyFz均成正相关、而铣削速度对Fz正相关,其余负相关,其中铣削深度对铣削力影响程度最大,而铣削速度影响程度最小;利用SPSS对正交仿真数据进行处理,建立GH536铣削力预测模型,并对模型进行回归分析;设计铣削测力试验,将其结果与铣削力预测模型进行对比,并用铣削力理论模型求解结果作为参照对比,结果表明铣削力预测模型能够比理论模型更准确的预测GH536切削过程中的铣削力。

    Abstract:

    The milling force and temperature were relatively large in the milling process of super alloy and had a great influence on the surface quality and tool life. The milling process of GH536 was modeled and simulated by using finite element analysis method. The milling force prediction model of GH536 was established and the regression analysis of the model was carried out. The milling experiment scheme was designed and the simulation results were verified and analyzed. The simulation results show that milling depth, milling width and feed per tooth are positively correlated with FxFy and Fz, while milling speed is positively correlated with Fz and negatively correlated with Fx and Fy. The milling depth has the greatest impact on the milling force, while the milling speed has the least impact; the milling force experimental results show that the established milling force prediction model can predict the milling force more accurately than the theoretical model in GH536 cutting process.
