Experimental Study of Shear Spinning

Abstract

Many researchers have done some work on the analysis of shear spinning process. But their works are limited to a certain extent. This paper deals with the experiment on the shear spinning process of aluminium to find out the fundamental characters in detail. The influence of the following working conditions is discussed ; roller position angle, clearance between roller and mandrel, feed of roller, cone angle, speed of rotation of mandrel, roller corner radius, roller diameter, blank thickness and blank diameter. In addition, the deformation theory of simple shear which is derived from the observation of the experiments, is checked about tangential force P_θ. It is said that there is an optimum blank thickness t_s, of which the calculated values agree with the experiments, and if the blank thickness is smaller than t_s, the theoretical value is overestimated, but underestimated, if it is the other way round.
