Optimization of Process Parameters of Thin Aluminum-Lithium Alloy Sheet Metal Laser Forming Based on Water-Cooling
Laser forming is a new flexible sheet metal forming process. By means of the theory of orthogonal experimental design method, design of experiment and optimization were carried out on thin aluminum-lithium alloy AA2090 sheet metal laser forming under the condition of water-cooling. And through the calculation and analysis of the experiments, the effect of the four process parameters related to the energy of laser beam on bending angle under the condition of water-cooling were ranked in order of laser power, number of scan, scan speed and beam diameter. Furthermore, the optimum process parameters were obtained, and experiment verifications were carried out.
