Machines use hydraulic or pneumatic 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.
The operations associated with stamping are blanking, piercing, forming and drawing, These operations are done with dedicated tooling also known as hard tooling. This type of tooling is used to make high volume parts of one configuration of part design. All these operations can be done either at a single die station or multiple die stations — performing a progression of operations, known as a progressive die.
