MODULE 5 SHEET METAL OPERATIONS
www.rajagiritech.ac.inSheet bending Sheet bending is defined as the straining of the metal around a straight axis. During bending operation, the metal on the inner side of the neutral plane is compressed, and the metal on the outer side of the neutral plane is stretched. Bending causes no change in the thickness of the sheet metal.
