Laser cutting is an essential application technology in the laser processing industry. Due to its many characteristics, it has been widely used in industrial sectors such as automotive, locomotive and vehicle manufacturing, aviation, chemical, light industry, electrical and electronics, petroleum and metallurgy. In recent years, laser cutting technology has developed rapidly, with an annual growth rate of 20% to 30% internationally. Since 1985, China has been growing at a rate of over 25% per year. Due to the poor foundation of China's laser industry and the limited application of laser processing technology, there is still a significant gap in the overall level of laser processing compared to other countries. It is believed that with the continuous progress of laser processing technology, these obstacles and shortcomings will be resolved. Laser cutting technology will inevitably become an indispensable and important sheet metal processing method in the 21st century. The broad application market of laser cutting processing, coupled with the rapid development of modern science and technology, has led domestic and foreign scientific and technological workers to continuously explore and research laser cutting processing technology, promoting the continuous development of laser cutting technology.

(1) With the development of high-power lasers and the adoption of high-performance CNC and servo systems, using high-power laser cutting can achieve high processing speeds while reducing the heat affected zone and thermal distortion; The thickness of the material sheet that can be cut is further increased, and high-power lasers can produce high-power lasers by using Q-switches or loading pulse waves.

(2) Based on the influence of laser cutting process parameters, improve the processing technology, such as increasing the blowing force of auxiliary gas on the cutting slag; Adding slag making agents to improve the fluidity of the melt; Increase auxiliary energy and improve the coupling between energy sources; And switch to laser cutting with higher absorption rate.

(3) Laser cutting will develop towards high automation and intelligence. Develop a highly automated multifunctional laser processing system by applying CAD/CAE/CAM and artificial intelligence to laser cutting.

(4) Adaptively controlling laser power and laser mode based on processing speed or establishing a process database and expert adaptive control system can generally improve the performance of laser cutting machines. Using a database as the core of the system and oriented towards a universal CAPP development tool, analyze various types of data involved in laser cutting process design and establish a suitable database structure.

(5) Developing towards multifunctional laser processing centers, integrating quality feedback from various processes such as laser cutting, laser welding, and heat treatment, fully leveraging the overall advantages of laser processing.

(6) With the development of the Internet and WEB technology, it has become an inevitable trend to establish web-based network databases, use fuzzy reasoning mechanisms and artificial neural networks to automatically determine laser cutting process parameters, and be able to remotely access and control the laser cutting process.

(7) In order to meet the needs of cutting three-dimensional workpieces in industries such as automobiles and aviation, 3D high-precision large-scale CNC laser cutting machines and their cutting technology are being widely developed in the direction of forward accuracy, high precision, multifunctionality, and high adaptability. The application range of laser cutting robots will become increasingly wide. Laser cutting is developing towards laser cutting unit FMC, unmanned and automated direction.
