Sheet metal bending (Sheet Metal Bending), the bending and forming of the metal sheet is carried out on the bending machine, the workpiece to be formed is placed on the bending machine, the brake shoe is lifted with the lifting lever, and the workpiece is slid to the proper position. position, and then lower the brake shoe onto the workpiece to be formed, and bend the metal by applying force to the bending lever on the bending machine.

The minimum bend radius is a function of the ductility and thickness of the formed metal. For aluminum sheets, the bending radius of the metal is greater than the thickness of the sheet. When bending, due to certain springback, the bending angle of the metal is slightly larger than the required angle. The bending of sheet metal is carried out in a metal workshop.
