Research on selecting approach of ANN training samples based on taguchi method and its applications to cold extrusion process design

Part shape plays great role in setting down the process design project.Therefore,in order to simplify the problem,the cold extruded parts were classified according to their shapes first of all,taguchi-method-based training sample subset standing for different part sort was established,and then the original whole training set was formed through the combination of all the subsets.In the end of this paper,the selecting process of taguchi-method-based training sample subset was analyzed,the taguchi-method-based training and testing process of ANN was also discussed,ANN based cold extrusion process design was carried out,by applying typical cold extruded part.
