Abstract
A spin forming process and apparatus is disclosed. A workpiece (e.g. sheet metal) is rotated with respect to a forming roller which bears against one of the outer and inner surfaces of the workpiece to deform the workpiece towards a required shape. First and second support rollers bears against the opposite surface of the workpiece. Computer control of the positions of the forming roller and the first and second support rollers allow non-axisymmetric shapes to be manufactured by spin-forming.
