Sheet metal is thin and flat pieces of metals. It is one of the fundamental forms used in metalworking and can be cut and bent into a variety of different shapes. Countless everyday objects are constructed of the material. Thicknesses can vary significantly, although extremely thin thicknesses are considered as foil or leaf, and pieces thicker than 6 mm (0.25 in.) are considered plate. In this text, we will discuss about basic operations in sheet metal.
