Discussion of Application of Laser Processing Technology in Metal Plate Process

Laser cutting technology has more advantages in reducing cost than traditional processing technology, as the laser beam is always existed in the form of a point, so it is very flexible in two-dimensional plane processing. In the process of laser cutting machine, Shanghai laser cutting only move its head, but another workpiece is still, without the need to set the micro connection, which is helpful to make the laser in the cutting process easier. Its computer CAM system does not need to make a manufacturing process for a single part, just to optimize the layout of the results and the cutting route, and then start the laser to be processed. But in the compound machine, the it need mould setting, the laser cutting route presupposition, and the setting of the connecting part, then the next step can be performed. By contrast, the preparation time of laser cutting machine is much less than that of compound machine. In actual application, when the machine is processed, because of the dragging of clamp and the drop of the mould, there will be some dead zone on the raw material. However, as laser cutting machine is still when it is cutting the workpiece, there is no dead zone, thus the utilization rate of the raw material is improved and so as the efficiency, the cost of raw materials consumed by a single process is greatly reduced. In recent years, the machining accuracy of laser cutting has been gradually improved, which greatly simplifies some processing procedures and reduces the processing cost of single parts. At the same time, the machining time of the workpiece is greatly reduced because of the rapid improvement of the cutting speed of the laser cutting machine. At the same time, the individual production efficiency of the operator has also been greatly improved.

The accuracy of products processed by laser cutting is further improved.
As the speed of laser cutting is increasing, the range of the workpiece's processing heat is gradually reduced, and the amount of thermal deformation that appears in the work of cutting process is also reduced. Meanwhile, as the stability of CO2 laser increases, the smoothness of laser cutting surface will also increase. In addition, the static processing of the workpiece greatly reduces the vibration. Because of the continuous improvement of the precision level of laser cutting, the laser cutting of agricultural machinery sheet metal parts has also been gradually changed, from the original low precision to high precision. From the actual situation of production, the original composite machine APELIOII 357 is usually a part with the thickness less than 2mm, which is mainly processed by the outsourced components of the spinning machine. Now, laser cutting machine not only can process the above part, but also can process the part with the thickness of 3mm--4mm or even larger than 6mm. Most of these parts are structural parts, transmission parts and main work parts. The requirements for machining precision are high, in which some parts are close to the precision requirements of the machining ones. The laser cutting parts not only have the characteristics of small deformation and high finish of the machining surface, but also have the characteristics of small burr and not even the size consistency of the parts. It has the greatest function in the precision control of the assembly dimension of the agricultural machinery.
