| Abstract: | Combined with a virtual simulation system of peripheral milling process and cutting force signal obtained in cutting trials,an optimal BP neural network model with 1-20-1 structure that can be used rapidly to predict vibration in peripheral milling process is trained and established.The estimation results of vibration displacement obtained from the BP neural network model have a good agreement with the experimental results,which reveals that neural network technique combined with the virtual simulation system can be used effectively to predict and monitor vibration in peripheral milling process under different cutting parameters. |
