Key points of sheet metal processing
In sheet metal processing, force is applied to the plate-shaped metal in various ways to form the target shape. The principle is related to the characteristics of the metal material. When a load is applied to a metallic material, the material changes the distance between its constituent atoms and deforms while creating strains. At this point, the force that the metal was trying to return to its original state from the beginning (internal force) comes into play, so when the load is small, if the load is removed, the metal will return to its original state (elastic deformation). When a load is continuously applied to a metal beyond a certain point (yield point), the metal cannot recover (plastic deformation). If the load continues to be applied, it will be overwhelmed and break. In sheet metal processing, it is important to have the technology to adjust while processing so that the target shape can be obtained through plastic deformation.
