Abstract：

In order to study the influence of counter spinning process parameter on wall thickness difference and expanding diameter, the spinning process of cylinder was set based on its technical features by finite platform ANSYS software. Then, three dimensional finite element model was set, and the numerical simulation was carried out. Furthermore, the forming process parameters of counter roller spinning were analyzed by orthogonal tests, and order-sequence factors of influencing wall thickness difference and expanding diameter were obtained. The result shows that in the process of counter roller spinning forming, the order sequence of factors influencing wall thickness difference are thinning rate＞feed ratio＞roller fillet radius, and the order-sequence of factors influencing expanding diameter are thinning rate＞roller fillet radius＞feed ratio.
