This paper deals with a theoretical study of shear spinning process, which was clarified by the experiments described in the previous report. Assuming that the deformation in shear spinning is divided into the three parts, which are redundant bending at the start line of contact, shearing, and bending on the contact surface between the roller and the blank, tangential force is evaluated from the total work of deformation in an infinitesimal time interval. The calculated results are checked not only by the experimental results of the previous report, but the data of Spincraft, Cincinnati and S.Kobayashi's reports. The state of contact between the roller and the blank is indicated numerically for several working conditions by introducing the contact factor m. In addition, it is shown that axial and radial force components can be estimated approximately by the optimum angles of frictional components ν_θ and ν_θ.
