Agricultural machinery products sheet metal processing parts have a wide variety of updates. Traditional agricultural machinery products sheet metal processing parts usually use the punching method, and the mold consumption is large. If the processing of parts still stays in the traditional way, it will seriously restrict the upgrading of the product and reflect the flexible processing characteristics of the laser. With the help of modern CAD/CAM software, laser processing can realize a variety of shapes of plate cutting, the use of laser processing, not only fast processing speed, high efficiency, low cost, but also do not need to change molds or tools, shorten production preparation time. It is easy to realize continuous processing, short laser beam transposition time, and high production efficiency. A wide range of workpieces can be mounted alternately. When machining workpieces, the finished parts can be unloaded and the workpieces to be machined can be installed to achieve parallel machining.
