Numerical control laser processing technology and application Pick to: as the main symbol of science and Technology development in the 20th century and the modern information society one of the pillars of optoelectronic Technology, Laser Technology, Laser Technology) and the development of Laser industry attaches great importance to by the advanced countries in the world. Numerical control and integrated the Laser and the optical system of the computer numerical control technology, advanced and high precision and automation of the workpiece positioning, the combination of formation, development and production of machining center has become a Laser machining, Laser Processing) is an important trend of development.

Key words: CNC; Laser machining, Laser Processing); Level; application

Before: laser is regarded as one of the most important scientific discoveries of the twentieth century, as soon as it was caused the great attention of materials scientists. In November 1971, gm pioneered the use of a 250 w CO2 laser to improve wear resistance materials using laser radiation test and research, and in 1974 successfully completed automobile redirector shell

surface (malleable iron material) laser quenching process, the wear-resisting performance of the hardened parts up to 10 times higher than that of untreated before. This is the first time laser surface modification technology of industrial application. Over the years, the nations of the world into a large amount of money and manpower to laser, laser processing equipment and laser processing and the study of material science, laser processing has been rapid development, and have gained great economic and social benefits. Now in China, the laser technology has been in industry, agriculture, medicine, war industry and get wider

in people's modern life Widely used, and gradually realize industrialization of laser technology, countries will it as a research one of the key projects of the ninth five-year plan. Overview, Laser Technology, Laser Technology)

Laser processing technology is the use of the characteristics of the interaction between laser and material on the material (including metal and nonmetal) for cutting, welding, surface treatment, punch and a processing technology of micro processing, etc. Laser processing technology is involved in optical, mechanical, electrical, materials and testing different subjects, such as, a comprehensive technology, its research scope in general can be divided into:

1. The laser processing system. Including laser, light system, machine tools, control system and testing system.

2. Laser processing technology. Including cutting (laser beam cutting), Welding, laser Welding), surface treatment, punching, marking, marking, trimming, etc. Various kinds of processing technology.

Has the mature processing technology include: laser rapid prototyping technology, laser welding, laser drilling, laser cutting, laser marking, laser to weight balance technology, laser etching, laser trimming technology, storage technology, laser marking, laser cleaning, laser heat treatment and surface treatment technology.

Second, the application of laser processing technology

CO2 laser laser processing applications, the most widely in cutting and welding, accounted for 70% and 20% respectively, surface treatment is less than 10%. The YAG laser application in welding, mark (50%) and cutting (15%). CO2 laser in the United States and Europe accounted for 70-80%. In laser processing is given priority to with cutting accounted for 10%, of which more than 98% of the CO2 laser, power within the scope of the 1.5 kW ~ 2 kW, and given priority to with heat treatment accounted for about 15%, mostly for laser processing
