Metal spinning, an incremental forming process

Abstract

Recent changes in product development processes have increased the demand for sheet metal parts manufactured in low volumes with the minimum investment in tooling. Spinning and a related process called 'incremental stretch forming' have shown potential for meeting this demand. Metal spinning is a long established process with low tooling costs that can be used to form a flat sheet metal blank into a hollow rotationally symmetric part. For the purposes o f this project spinning was taken as a representative incremental forming process, i.e. a process where the deformation is achieved incrementally.
