Sheet metal is metal formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Countless everyday objects are fabricated from sheet metal. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate.
Sheet metal forming processes are those in which force is applied to a piece of sheet metal to modify its geometry rather than remove any material. The applied force stresses the metal beyond its yield strength, causing the material to plastically deform, but not to fail. By doing so, the sheet can be bent or stretched into a variety of complex shapes.
Sheet metal forming is used in almost every sector of Prototype industrial production like Automotive industry( doors, hoods, fenders) Aircraft industry(wings, fuselage)Home appliance industry(sinks, cooker hoods, freezers) and so on.
Sheet metal forming processes include the following:
Bending is a metal forming process in which a force is applied to a piece of sheet metal, causing it to bend at an angle and form the desired shape.
Roll forming, sometimes spelled roll forming, is a metal forming process in which sheet metal is progressively shaped through a series of bending operations
Spinning,is a metal forming process used to form cylindrical parts by rotating a piece of sheet metal while forces are applied to one side.
Deep drawing is a metal forming process in which sheet metal is stretched into the desired part shape.
Stretch forming is a metal forming process in which a piece of sheet metal is stretched and bent simultaneously over a die in order to form large contoured parts.
