The application of laser cutting technology involves more and more fields, which brings a lot of improvement to social production efficiency. So, what is the development direction of laser cutting technology in the future?
1. With the development of laser towards high power and the use of high-performance CNC and servo system, high processing speed can be achieved by using high-power laser cutting, while reducing the heat affected zone and thermal distortion; The material plate thickness that can be cut is further improved. High power laser can produce high power laser by using Q switch or loading pulse wave.
2. According to the influence of laser cutting process parameters, improve the processing technology, such as: increase the blowing force of auxiliary gas on the cutting slag; Adding slagging agent to improve the fluidity of melt; Increase auxiliary energy and improve the coupling between energies; And laser cutting with higher absorption.
3. Laser cutting will be highly automated and intelligent. CAD/CAPP/CAM [4] and artificial intelligence are applied to laser cutting to develop a highly automated multi-function laser processing system.
4. The performance of laser cutting machine is generally improved by adaptively controlling the laser power and laser mode according to the processing speed or by establishing the process database and expert adaptive control system. With the database as the core of the system and facing the general CAPP development tool, the various data involved in laser cutting process design are analyzed, and the corresponding database structure is established.
5. Develop to a multi-functional laser processing center, integrate the quality feedback after laser cutting, laser welding, heat treatment and other processes, and give full play to the overall advantages of laser processing.
6. With the development of Internet and Web technology, it is an inevitable trend to establish a Web based network database, use fuzzy inference mechanism and artificial neural network to automatically determine laser cutting process parameters, and be able to remotely access and control the laser cutting process.
7. 3D high-precision large-scale CNC laser cutting machine and its cutting process technology, in order to meet the needs of cutting three-dimensional workpieces in automobile, aviation and other industries, 3D laser cutting machine is developing in the direction of high efficiency, high precision, multi-function and high adaptability, and the application range of laser cutting robot will become larger and larger. Laser cutting is developing towards laser cutting unit FMC, unmanned and automatic.
Laser cutting technology is clean, safe and pollution-free, which greatly improves the working environment of operators. Of course, in terms of precision and surface roughness of incision, CO2 laser cutting cannot exceed electric machining; In terms of cutting thickness, it is difficult to reach the level of flame and plasma cutting. But the above remarkable advantages are enough to prove that CO2 laser cutting has replaced and is replacing some traditional cutting methods, especially the cutting of various non-metallic materials. It is an advanced processing method with rapid development and increasingly wide application.
