This paper deals with a theoretical study of shear spinning process, which was clarified by the experiments described in the previous report. Assuming that tha deformation of 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, the tangential force are evaluated from the total work of deformation in an infinitesimal time interval. The calculated results are checked not noly 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 are indicated numerically for several working conditions by introducing the contact factor m. In addition, it is indicated that the the axial and radial force components can be estimated apploximately by the optimum angles of frictional components υ_θ and υ_ψ.
