Stamping (also known as pressing) is the process of placing flat sheet metal
in either blank or coil form into a stamping press where a tool and die surface
forms the metal into a net shape.
Stamping includes a variety of sheet metal forming manufacturing processes,
such as punching using a machine press or stamping press,blanking ,embos-
sing,bending ,flanging,and coining. This could be a single stage operation 
where every stroke of the press produces the desired form on the sheet metal
part,or could occur through a series of stages.
The process is usually carried out on sheet metal ,but can also be used on other
materials, such as nylon.
