Based on these results, a routing about how to select spinning parameters has been gradually formed. However, ball spinning, due to its own features plus research lack, is stili unclear about its parameter selections. In addition, some manufacture-enterprises only notice the use of this technique whereas ignore the theory creation. The optimal parameters about the ball spinning although have been released from these enterprises but in fact not a helpful theory for other researchers and producers. Focus on selecting the parameters based on the trial-and-error, this article has carried a series of experiments to study the influence on the spinning working course from those parameters, especially the peeling phenomena, and the tube diameter bulging. An optimal graph of the vvorking angle, the axial feeding rate, and the acceptable vvorking course is put forward. Additionally, based on the theory of the minimal reduction rate, the selection of the bail diameter is finally described. Thus, it has given the rules to get the proper parameters in ball spinning.展开更多
