It is often necessary to manufacture sheet steel parts by metal forming machines. The most common of these include wheeling machines, guillotines, fly presses, folders and forming presses. In body repair shops the fly press is often hand operated and is a most useful piece of equipment. Tools for the fly press fit into a central spindle, which is moved down in order to pierce, blank and, to a limited extent, form the metal parts required. Another widely used machine is the folder or bending machine; adjustment of the setting of the blades of this machine enables sharp acute or obtuse angled bends to be produced in long lengths of sheet metal for the making of sections. The swaging machine is used for swaging, wiring, joggling and closing sheet metalwork edges. Finally, the bodyshop is not complete unless it possesses a wheeling machine, which is used to produce double-curvature panels from flat sheets by passing the sheets to and fro between rollers or wheels in order to stretch the sheets and to create a curved shape.

A bending machine is a forming machine tool that allows to manufacture a workpiece by using a bending tool and an ordered sequence of linear and rotational motions. The shape of the manufactured workpiece depends on the characteristics of each motion, i.e., position and velocity profiles, and on the sequence in which motions are executed.
