[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car body), etc. Its most notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used as the name during assembly.

[0003] During the forming process of sheet metal parts, punching is used to punch holes in the workpiece for forming.
