Abstract：
|
|
A method for designing the blank was researched:blank optimization design based on ANN model,using mapped relation reflected by ANN to achieve the forecast blank of congeneric parts. The design principle and process were expatiated,and some key technologies ,such as radial basis function neural network,transforming blank contour to the output parameters of ANN and using modified blank as training sample to increase design precision were expatiated. The results show that,if the ANN is trained successfully,the suitable blank can be obtained rapidly,which has great economic benefits.
