[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching, cutting, compounding, bending, welding, riveting, splicing, and forming (such as automobile bodies). Its significant characteristic is that the thickness of the same part is consistent. Products processed by sheet metal processing are called sheet metal parts. Sheet metal parts are components with specific shapes and functions that are transformed from thin metal sheets through specific cold working processes.
