Also 3-roll-bending is used for producing work pieces with large bending radii. The method is similar to press bending, but the working cylinder and the two stationary counter-rollers rotate, thus forming the bend. Compression bending is carried out with a sliding carriage and a stationary bend die, between which the pipe is clamped.

Abstract— In the three roller bending machine, the three rollers rotate. Bending can be done in both sheet metal and bars of metal. For designing a three roller bending machine, it is required to calculate the exact force for bending. Based on this force, the machine parameters and motor power are decided.

Nowadays for construction works bending of metal sheet is necessary for constructions. Bending of such metal sheet is done manually by setting angle plates. This wastes lot of labour (man) power and time. It is proposed to replace the manual work and reduce time taken for bending by designing an alternative machine to replace the manual work

The bar bending machine consists of an electric motor, a coupling, a circular plate, a worm gear drive, and an extended shaft. An electric motor transmits power to a gearbox, which decreases speed and increases torque. A circular plate bends the bar using this gearbox. It can usually bend bars in the range of 6 mm to 16 mm.
