Laser cutting die stamping is to use a high power density laser beam to directly inject the material to be cut, so that the material is rapidly heated to the vaporization temperature, volatilized to generate holes, and as the beam penetrates the material Moving on, the eyelet continuously produces cuts with a very narrow overall width, completing the cutting of the material. Laser cutting is divided into four types: laser vaporization cutting, laser fusion cutting, laser O2 cutting and laser lithography and controlled cracking. Most laser cutting is controlled by numerical control programs, or made into cutting robots. In the automobile manufacturing industry, modern factories use highly intelligent laser cutting robots. Volkswagen of Germany uses a laser with a power level of 500W to cut various complex body sheets and various curved parts. In the aerospace field, special aerospace materials such as titanium, aluminum alloys, nickel alloys, chromium alloys, stainless steel, beryllium oxide, composite materials, plastics, porcelain and quartz are cut according to laser cutting technology. In some specific processes, laser cutting has scratches on the cutting edge and burrs on the tiny processing, so the stamping process becomes an area of consideration.
