Punching: Punching is a fabricating process in which a steel tool, called a punch, is forced into sheet metal, forcing it to compress or release into a bottom die. Forming punches compress the sheet metal into the shape of the bottom die to create the desired contour. Hole, slot and notch punches are used to cut holes in sheet metal by shearing the metal into a hollow die, where the excess metal drops to the bottom and is collected.
