A metal-forming process is used for production of hollow, rotationally symmetric sheet metal components. To produce a component with a given shape and thickness distribution, the sheet is clamped to a rotating rigid mandrel and formed by a roller tracing the shape of the mandrel at a fixed distance.
Theory and Application
Shear forming belongs to a group of processes used for production of hollow, rotationally symmetric parts. The term spinning is used to refer to the three processes in this group: metal (conventional) spinning, shear forming (shear spinning), and flow forming (tube spinning). The main difference between the three processes is the wall thickness of the formed part. While metal spinning preserves sheet thickness, shear-forming and flow-forming thickness is deliberately reduced to obtain a given part shape and thickness distribution.
