Stamping is mainly classified according to process, which can be divided into two categories: separation process and forming process. The separation process, also known as blanking, aims to separate the stamping parts from the sheet along a certain contour line and ensure the quality requirements of the separated section. The purpose of forming process is to make the sheet metal plastically deform and make the workpiece have the required shape and size without destroying the blank.

In actual production, a workpiece often goes through multiple processes. Stamping, bending, shearing, stretching, bulging, spinning and straightening are the main stamping processes.
