Abstract
Industrial metal spinning depends on costly trial-and-error when introducing new products. However, a recently developed flexible spinning setup allows a new form of process operation similar to raising by hammering: two rollers on either side of the rotating workpiece apply a couple to deform it locally whilst moving towards its edge. This paper presents this configuration for the first time and develops and verifies an upper bound yield-line model to design stable tool-paths that avoid wrinkling. Raising by spinning is shown to be feasible and more stable than conventional spinning, paving the way for automatic production of deep axisymmetric shapes.
