| 摘 要： | 利用2kW CO2激光器研究了低碳钢板料的激光弯曲情况，试验结果表明，对于多道扫描激光成形工艺，弯曲角度受到许多工艺参数的影响。其中，激光功率、光束直径、扫描速度、扫描次数、板料厚度等参数的效应尤其显著。对试验结果的定性分析，所得的结论可为激光弯曲成形技术的进一步理论研究和可能的工业应用提供依据。

| Abstract: | In this paper, the bending behavior of low carbon steel sheets is studied after being irradiated by an axial CO 2 laser beam. The experimental results show that the final bending angle of the sheets in a multiple-irradiation laser bending process is related to many process parameters, especially, laser power, beam diameter, path feed rate, number of irradiation and sheet thickness. By qualitative analysis of experimental results, the conclusion obtained may provide basis for theoretical investigation and possible industrial application of laser bending process in the future. |
