Laser cutting machine processing aviation aluminum processing technology

Laser cutting machine processing aviation aluminum technology in the laser cutting system, the limitations in the laser cutting applications in aviation are improved, these limitations include fatigue performance and lower manufacture process consistency problem. Now, the laser system to a great extent reduced the heat affected zone ( HAZ) The size and the corresponding haircuts. In the process of laser cutting, the technical personnel can control the cutting parameters, and use of calculator software for precise repetition. Whether the technology progress of laser cutting is suitable for the production to rethink of the fuselage structure. Fuselage structure mainly 7000 series aluminum material. Laser cutting process can be faster processing consistent parts, it is more efficient than the traditional processing. Laser technology is expected to reduce the processing time and the cost of production. For a long time, in the 7000 series of aluminum processing, the advantages of laser has been due to the reduce of fatigue performance failed to get to play. Close, laser system innovation has made people to evaluate the superiority of laser cutting air with aluminum. Preliminary tests have shown that laser technology in the potential of the fuselage processing. Body system in the future as well as the existing design should not be ruled out because of the past experience of laser in the body might be applied in the system. We should keep an open attitude to analyze all kinds of situation, in order to determine the laser technology can bring the product benefits. In stress concentration on fatigue fracture often takes place after place, such as the edge of the parts, geometry shape change, or joint. Sheet metal body parts have a lot of different ways of bonding, the vast majority of fatigue cracks occur in the joint. If the laser is not used for cutting joint holes, then the edge cutting of laser is mainly used for parts. For other effect, can be illustrated by using the connection position of the easily damaged compared with joint, laser cutting of micro cracks and the major damage.
