Spinning, sometimes called spin forming, is a metal forming process used to form cylindrical parts by rotating a piece of sheet metal while forces are applied to one side. A sheet metal disc is rotated at high speeds while rollers press the sheet against a tool, called a mandrel, to form the shape of the desired part.

Simply put, sheet metal press forming (or metal fabrication) is the process associated with burning, cutting, or welding sheet metal. In this case, the goal is to form a specific shape while maintaining the overall quality and strength of the metal itself. Typically, when the material (i.e. steel or aluminum) has a thickness that is less than 6 ...

A non-associated flow rule model. The proposed model is developed from the FEM model described by Wang and Budiansky (1978). The material model is still assumed be rate-insensitive, and have positive isotropic work hardening. The sheet thickness is assumed to be small so that the equations for membrane theory apply.

With respect to sheet metal working, bending stands at the top alongside deep drawing. Besides sheet metal, ribbons, pipes, wires and rods are formed using very different bending processes. Typical forming machines are used in the process, such as presses, folding machines, profile rolling machines and bending machines with rolls.

Roll forming is the continuous bending of a long strip of sheet metal. This is typically coiled steel into a cross-section (profile). The strip passes through sets of rolls mounted onto consecutive stands, each set performing an incremental part of the bend, until the desired cross-section is obtained. Roll forming is ideal for producing ...
