Bending is a metalworking process used to permanently deform a workpiece, usually a sheet or a tube of metal, into a desired shape or angle. It is accomplished by applying force on the workpiece, which causes it to bend at a specific angle or radius. The bending process is widely used in the manufacturing of metal products such as pipes, tubes, sheet metal, brackets, and other structural components. The bending operation can be performed using various techniques such as press brakes, roll benders, tube benders, and others.
