Reverse Design of Cam Contour Curve Based on BP Neural Network

To improve precision of reverse design in cam contour curve, method of using BP neural network was presented. The theory and algorithm of BP neural network were introduced, the principle and process of BP neural network modeling used in the reverse design of cam contour curve were expounded, and the actualize method of reverse design with modeled network was afforded. Experiment indicates that this method is suitable to reverse the contour curve of cam, and has high approach precision. At last, disadvantages of the method were discussed.
