Metal spinning is used to form hollow, axially symmetric sheet components. However, it is limited by two features: a die (mandrel) is required for each product; the process is limited to production of axially symmetric components. Spinning has developed over time with major improvements in automation and quality of produced parts. Yet, given its age, the process has seen almost no change from the original configuration and the two limitations have not yet been overcome successfully. This study presents new insight into the role of the mandrel in spinning, which has led to design of a novel process allowing mandrel-free production of non-axisymmetric components.
