| 摘 要： | 根据热缩加长刀杆与刀具配合精加工与半精加工的特点,利用反向传播神经网络(BPNN)建立高速加工热缩加长刀杆与刀具配合的铣削力模型。模型除了考虑6个主要影响铣削力的加工条件外,还将时间参量引入输入向量,实现了三向铣削力的瞬态预测。通过大量的加工实验获得网络所需的训练和检验样本,并通过编制Matlab程序实现了网络性能评价和网络参数优化。检验结果表明,铣削力预测结果与实际测量结果之间具有很好的一致性,三向分力的平均预测误差均小于0.18,在预测效率和精度上均优于通常所用的解析模型,并具有很好的扩展性能。

| Abstract: | Current research focuses on developing a milling force model according to the characteristics of the matching of lengthened shrink-fit holder and cutting tool using back propagation neural network(BPNN).Time parameter is taken as a factor of the input vector besides six processing conditions which mainly influence the milling force,and then the forecasting of 3D transient milling forces are achieved.In order to get training and testing samples,a lot of milling experiments are performed and a Matlab program ... |
