Other AbstractShape correction is an important tool in ensuring the forming precision of sheet metal parts. In order to improve the correction effect and efficiency, a new method of laser correction of thin-walled aluminum alloy part is proposed. When laser beam irradiates the residual stress gathering area of the formed part, the elastic energy in this area is transformed into plastic work due to laser thermal effect, thus the forming error is corrected and the forming precision is improved. The formed part is produced by standard three-point bending test, and then laser beam scans it along the bending line, so that the actual correction values are obtained. The correction effect is discussed through the quantitative analysis of the experimental data. The actual correction rate varies with the choice of material and thickness of specimen. The feasibility of the laser correction technique is verified. Research foundation is laid for further application of laser correction in engineering.
