The advantage of laser cutting machine in cutting aluminum plates is that it can quickly and correctly process aluminum foil into different shapes. The advantage of this technology makes the laser cutting equipment attract many airlines as soon as it is commercialized. In the 1970s, major manufacturers evaluated the laser cutting technology and found that the micro cracks produced by laser processing could not damage the processing characteristics of the tired pure aluminum plate of the parts. The potential weight gain has damaged the interests of the manufacturing industry, making laser cutting technology shelved by major fuselage manufacturers.
In addition to the problem of micro cracks, it is also found that the parameters of laser cutting technology are difficult to control and can hardly be tested. In the current international manufacturing market, it is increasingly important to strictly control all processing and inspection of characteristic parameters, because these processing jobs are more outsourced to peripheral suppliers.
Fatigue fracture usually occurs at the place of stress concentration, such as the edge of the part, the change of geometric shape, or the joint. The fuselage parts made of thin ceiling aluminum plate processing plate metal have many different joint methods, and most of the fatigue cracks occur at the joint. If the laser is not used to cut the small hole at the joint, then the laser is mainly used for edge cutting of parts. For other effects, the connection position that is easy to be damaged can be used to explain that compared with the connection, the micro cracks caused by the laser cutting machine are not the main damage position. In this way, we can conclude that if a part is likely to break at the connection, the laser cutting technology will not further damage the fatigue characteristics of the part.
