An investigation into material wrinkling failure mechanics of conventional metal spinning and the effects of process parameters and material properties are presented in this paper. By developing finite element (FE) models using the Box-Behnken design of experiments, the effects of six key process and material parameters on the start of material wrinkling have been investigated. These key factors include roller feed per pass, feed rate, blank thickness, tool path profile, material Young’s modulus, yield stress and strain hardening exponent. The results of FE simulation are validated by comparing the modelled roller tool forces and spun part end shape with those measured during a spinning experiment.
