为了实现对加工过程中铣削力动态变化的预测,课题组构建了金属材料铣削力及振幅的预测模型。首先通过仿真与试验相结合的方法,探究不同材料在不同主轴转速和轴向切深下的铣削力特性;在确认仿真模型准确的基础上进行铣削力的正交仿真,采用回归分析的方法构建平均铣削力及振幅的预测模型。结果表明:不同材料的平均铣削力受主轴转速和轴向切深的影响不同,但铣削力的振幅大小与主轴转速和轴向切深均呈正相关。课题组所提出的铣削力及振幅预测模型可以为铣削参数的合理选择提供参考。 |

In order to predict the dynamic changes in milling force during the machining process,a prediction model for milling force and amplitude of metal materials was constructed.Firstly, the milling force characteristics of different materials under different spindle speeds and axial cutting depths were investigated by combining simulation and experiment. On the basis of confirming the accuracy of the simulation model, the orthogonal simulation of the milling force was carried out, and the prediction model of the average milling force and amplitude was constructed by using the regression analysis method. The results show that the average milling force of different materials is affected differently by spindle speed and axial cutting depth, but the amplitude of milling force is positively correlated with spindle speed and axial cutting depth. The proposed milling force and amplitude prediction model can provide reference for the reasonable selection of milling parameters. |
