Abstract：

As a successively and locally plastic deformation process, ball spinning is applied for the purpose of manufacturing thin-walled tubular parts of aluminum alloy. The basic principle with respect to ball spinning is introduced, and based on plastic mechanics, the influence of mechanical parameters on formability of spun parts is analyzed. During experiments, aluminum alloy LF2 and LY12 are used in order to obtain the influence of plasticity and yield strength of metal materials on spinnability of spun parts. In the end, the effect of attack angle on stable flow of metal materials is researched and the appropriate value of attack angle is derived from experiments.
