What is the future of laser cutting technology?

Laser cutting is the laser processing industry in the most important application of a technology, due to a number of characteristics, has been widely used in automotive, rolling stock manufacturing, aviation, chemical industry, light industry, electrical and electronic, petroleum and metallurgy and other industrial sectors. In recent years, laser cutting technology is developing rapidly, the international annual growth rate of 20% to 30%. China since 1985, more than 25% annual growth rate. Due to China's poor laser industrial base, the application of laser processing technology is not yet common, the overall level of laser processing compared with advanced countries still have a large gap, I believe that with the continuous progress of laser processing technology, these obstacles and deficiencies will be resolved. Laser cutting technology will become an indispensable and important means of sheet metal processing in the 21st century. Laser cutting and processing of the broad application market, coupled with the rapid development of modern science and technology, so that domestic and foreign science and technology workers on the laser cutting and processing technology to continue to explore the research, and promote the laser cutting technology continues to move forward.

(1) along with the laser to high-power development and the use of high-performance CNC and servo systems, the use of high-power laser cutting can obtain high processing speed, while reducing the heat-affected zone and thermal aberration; the ability to cut the material plate thickness is also further improved, high-power laser can be used through the use of Q-switching or loading of the pulse wave, so that the low-power laser to produce a high-power laser.

(2) According to the influence of the laser cutting process parameters, improve the process, such as: increase the auxiliary gas to cut the slag blowing force; add slagging agent to improve the fluidity of the melt; increase the auxiliary energy and improve the coupling between the energy; and switch to a higher absorption rate of laser cutting.

(3) laser cutting will be highly automated, intelligent direction. CAD / CAPP / CAM and artificial intelligence used in laser cutting, the development of highly automated multi-functional laser processing system.

(4) according to the processing speed adaptive control of laser power and laser mode or the establishment of process database and expert adaptive control system makes the laser cutting machine performance generally improve. Database as the core of the system, for the generalization of CAPP development tools, laser cutting process design involved in the analysis of various types of data, the establishment of a suitable database structure.

(5) to the development of multi-functional laser processing center, laser cutting, laser welding and heat treatment and other processes after the quality of feedback integrated together to give full play to the overall advantages of laser processing.

(6) With the development of Internet and WEB technology, the establishment of WEB-based network database, the use of fuzzy inference mechanism and artificial neural network to automatically determine the laser cutting process parameters, and can be accessed remotely from a different place and control of the laser cutting process has become an inevitable trend.

(7) three-dimensional high-precision large-scale CNC laser cutting machine and its cutting process technology, in order to meet the needs of automotive and aviation and other industries, three-dimensional workpiece cutting, three-dimensional laser cutting machine is to the high-efficiency, high-precision, multi-functional and highly adaptive direction of the people's development, the application of laser cutting robots will be more and more large. Laser cutting is moving towards laser cutting cell FMC, unmanned and automation direction.
