Sheet Metal Punching: Defined
Sheet metal punching in metal fabrication is the process of using a machine to press a shape through a sheet of metal and into a die to create the desired shape in the metal. This is most commonly done by use of a turret, a computer numerical controlled machine that houses tools and their corresponding dies in a revolving indexed turret. These machines use hydraulic, pneumatic, or electrical power to press the shape with enough force to shear the metal. The shape is formed by pressing the material against a die with a huge force. The shear forces generated between the material and die separate the material into the desired shape. The desired shape is not obtained, however, as burred edges and rough surfaces are formed. These edges and surfaces must be further processed until the desired shape is achieved.
