Stamping is a forming and processing method that applies external forces to plates, strips, pipes and profiles by means of presses and dies to produce plastic deformation or separation, so as to obtain the workpiece (stamping part) with the required shape and size.
There are also special machining, laser machining, EDM, ultrasonic machining, electrochemical machining, particle beam machining and ultra-high speed machining. Turning, milling, forging, casting, grinding, CNC machining and CNC numerical control center all belong to machining.
