Sheet metal bending is an operation that involves the use of force to change the shape of a sheet. This is done to obtain the shape or shape needed for the manufacturing process. The external force applied only changes the external characteristics of the sheet. However, sheet metal parameters for one type, such as length and thickness, remain unchanged. The ductility of the metal plate further enables it to be used in a variety of molding processes. Sheet metal methods include V bend, roll bend, U bend, wipe bend, rotary bend.
