The third category, requiring uniform kerf special parts. The most widely used packaging and printing industry is a typical part of the die used, it requires the template in 20mm thick wood cut out on the slot width of 0.7 ~ 0.8mm slot, and then embedded in the blade slot. Fashion in the cutting machine to use, good cut of the printed graphics box.The emissive power of the RF technology is low, so it is fit for green laser pointer using batteries. China in recent years, a new area of application of oil sieve slit tube. In order to block the sediment into the pump, the wall thickness of the steel pipe 6 ~ 9mm on uniform cut 0.3mm kerf width, cut from the perforation hole diameter can not 0.3mm, cutting technical difficulties, there are many units into production. Foreign addition to the above applications, is also expanding its applications. (1) Three-dimensional laser cutting system or configuration of industrial robots, cutting space curve, the development of three-dimensional cutting software, to speed up the parts from the drawing to the cutting process. (2)315GHz and 433GHz are the national emissive and received frequency for green laser pointer . In order to improve production efficiency, research and development of a variety of special cutting systems, material handling system, linear motor drive system, cutting system, cutting the current rate of more than 100m/min. (3) for the expansion of construction machinery, shipbuilding and other industrial applications, cutting mild steel thickness over 30mm, with particular attention to the study of low carbon steel with nitrogen cutting technology to improve the quality of cutting plate incision. Therefore, in China’s expanding CO2 laser cutting of industrial applications, new applications to solve some technical problems in engineering and technical personnel is still an important issue. Sixth, laser cutting laser cutting process parameters and the laws have cut the main process parameters laser power, the width of cut, cutting speed and gas flow. Laser Power: Laser cutting the size of the power required is determined by the material properties and cutting mechanism decision.The 315GHz and 433GHz of green laser pointer are fit for long-distance transmission. Cutting speed: power in certain conditions, the greater the thickness, cutting speed is smaller. Cutting speed of the cut surface roughness has a greater impact. Gas pressure: the power and cutting material thickness is constant, there is an optimal cutting gas flow, then cut the fastest. With the increase in laser power, cutting the gas flow is increased best. Beam quality, focal length and the amount of defocus: the laser output beam is TEM00 mode laser cutting when the most favorable. Spot size and focal length is proportional to the focusing lens. Although the short focal length lens can be smaller spot, but a very small depth of focus. Defocus amount of the cutting speed and cutting depth a greater impact, cutting the process must remain unchanged, the general negative selection from the coke, that is placed on cutting board focus position below a certain point. Nozzle: the nozzle is affecting the quality of laser cutting and efficiency – an important component. The 315GHz and 433GHz applied by laser pointer pen have strong diffracting power.Laser cutting is generally coaxial (concentric with the optical axis flow) nozzle, the nozzle exit diameter should be selected based on thickness. In addition, the distance from the nozzle to the workpiece surface, the distance must be maintained. Industrial materials, laser cutting: laser cutting of metal materials and non-metallic materials, laser cutting. Seven, the status quo of China’s laser cutting technology, laser manufacturing technology in China the level of research and application of the scale, compared with developed countries, the gap is large. In the industry, some in high-end laser products and their materials, components still remain in the development stage, or not scale, high-grade, high intelligence, high relative lack of automation of laser products.
