Laser cutting has been little known in the domestic sheet metal cutting field from the beginning to the full popularization today. With the increasing maturity and improvement of laser cutting machine technology in recent years, the future laser cutting equipment will be divided into two development paths. One is to upgrade and replace the existing technology. For example, when the thickness of plate is getting thicker and thicker, the cost is getting lower and lower; Another way is to study new cutting media and cutting methods. In the context of higher and higher requirements for processing efficiency, how to improve the efficiency of laser cutting machine?
1.To further improve the cutting efficiency, develop an efficient and high-precision CNC laser cutting machine and improve the cutting speed, we should not only improve the beam quality and change the cutting process, but also optimize the structure design of the machine bed and components, so as to make it have faster moving speed and acceleration on the basis of ensuring the stability, reliability and durability of the machine structure.
2.Develop the flexible processing of laser cutting, improve the various degrees of freedom of laser cutting machine, and make it more suitable for the processing of complex curved surface workpieces. Improve the popularization and application in two-dimensional and three-dimensional aspects, so as to improve flexible machining.
3.Increase the research on the laser cutting technology of large and thick plates, master the technology of long-range laser transmission, the technology of thick plate cutting, the design and manufacturing technology of the optical path of high-power laser, and develop large and thick plate laser cutting equipment.
4.Further improve the intelligence of the cutting machine, take the laser control software as the core, combine the fiber laser with CNC technology, optical technology and high-precision workpiece positioning through the software, combine some functional components of the laser cutting machine with other processing methods, and develop more convenient and fast laser processing methods and more efficient cutting processes.
Then, for the control system of a laser cutting machine, on the basis of ensuring stability, reliability and safety, efficient cutting efficiency and simple and diverse operation methods are more important. After more than 10 years of rapid development and growth, the control system and software of laser cutting machine have experienced several stages from foreign high-end CNC systems such as Siemens, Beifu, PA and Fage to domestic manufacturers such as FScut, Weihong, Jiaqiang and orsendico. The loading method of processing files is from the original simple G code to today’s intelligent processing. To sum up, there are several conventional processing methods as follows:
1.G code import: directly process by importing the G code written manually or generated by nesting software. This is the most traditional and stable processing method. Foreign systems basically use this method.
2.Drawing / part library processing: you can directly draw manually on the cutting software or call the part model of the part library, and the cutting software will automatically convert the graphics into G code for processing. This is the standard configuration of domestic laser cutting software, which is simple, convenient and practical.
3.Graphics import: the laser cutting software can support the direct loading and import of DXF / DWG and other CAD drawings, eliminating the intermediate operation link of using nesting software on other machines, and improving the efficiency.
4.Import of engineering documents: laser cutting not only includes G code, but also corresponding processing technology, which is more suitable for batch processing of some common products and special processes. Make it easier for customers to operate.
