Laser cutting technology is a comprehensive high-tech technology, which crosses the disciplines of optics, material science and engineering, mechanical manufacturing, numerical control technology and electronic technology. Over the past 50 years, laser processing technology and applications have developed rapidly and have been combined with multiple disciplines to form multiple technical application fields. The main processing technologies of lasers include: laser cutting, laser welding, laser marking, laser drilling, Laser heat treatment, laser rapid prototyping, laser coating, etc.
Laser cutting technology is the main application of laser technology in industry. It accelerates the transformation of traditional processing industry and provides new means of modern industrial processing. It has become the most widely used laser processing method in the current industrial processing field. At present, laser cutting technology has been widely used in machinery manufacturing, bridge construction, sheet metal processing, ship and automobile manufacturing, electrical and electronic industry, aviation and aerospace and other pillar industries of the national economy. With the continuous progress and application of science and technology, laser cutting technology will certainly further advance to other fields.
In recent years, laser processing technology has developed very rapidly, and its application has become more and more extensive, so laser is known as "universal processing tool" and "common processing method for future manufacturing systems". Due to the extensive application of laser processing technology, the production technology of enterprises in advanced industrial countries is undergoing qualitative changes. Laser cutting technology is the main application of laser technology in industry. It accelerates the transformation of traditional processing industries and provides new means of modern industrial processing. It has become the most widely used laser processing method in the current industrial processing field, accounting for the entire laser processing industry. more than 70%.
Laser cutting is to use a focused high power density laser beam to irradiate the workpiece. Under the premise of the laser power density exceeding the laser threshold, the energy of the laser beam and the additional chemical reaction heat energy of the active gas-assisted cutting process are all absorbed by the material, resulting in The temperature of the laser action point rises sharply. After reaching the boiling point, the material begins to vaporize and forms holes. With the relative movement of the beam and the workpiece, the material finally forms a slit, and the sediment at the slit is blown away by a certain auxiliary gas.
Laser cutting has been widely used in modern industry for its advantages of wide cutting range, high cutting speed, narrow slit, good cutting quality, small heat-affected zone, and large plus flexibility, and laser cutting technology has also become a laser processing technology. One of the most mature technologies in Compared with other light, laser has the following characteristics: high brightness, high directivity, high monochromaticity, and high coherence. It is precisely because the laser has these four characteristics that it has been widely used, which brings the following valuable characteristics to laser processing that traditional processing does not have:
(1) Due to the non-contact processing, and the energy and moving speed of the laser beam can be adjusted, various processing can be realized.
(2) It can be used to process various metals and non-metals, especially materials with high hardness, high brittleness and high melting point.
(3) There is no "tool" wear during laser processing, and no "cutting force" acts on the workpiece.
(4) The heat affected zone of the workpiece processed by the laser is small, the thermal deformation of the workpiece is small, and the subsequent processing amount is small.
(5) The laser can perform various processing on the workpiece in the airtight container through the transparent medium.
(6) The laser is easy to guide. It is easy to cooperate with the numerical control system to process complex workpieces through focusing, so that laser cutting is an extremely flexible cutting method.
(7) Laser processing has high production efficiency, stable and reliable processing quality, and significant economic and social benefits.
