机械加工尺寸预测的两种方法及其比较

Two Prediction Methods of Machining Dimension and Their Comparsion

将时间序列方法和神经网络方法在加工尺寸预测中的应用作了比较。在时间序列方法中 ,提出了数据序列加窗的方法以提高预测的准确性 ;在神经网络方法中 ,应用 BP网络模型 。

A comparison of dimension prediction is made between th e models of time series and ANN. In the time series model, a method of data wind ow is put forward to increase the prediction accuracy; in the ANN model, the app lication of BP ANN model is discussed in the dimension prediction.
