激光弯曲成形是一种热应力成形塑性加工技术。光斑的能量密度的大小对弯曲角度和材料的组织性能影响很大。增加能量密度 ,板料的弯曲角度显著增大。对于一种材料 ,总存在一组特定的工艺参数 (光束输出功率、扫描速度、光斑大小等 )使板料的弯曲角度最大。而且通过合理控制光斑的能量密度 ,可以显著改善变形区材料的组织和性能 Laser Bend Forming is a thermal stress forming plastic working technique. The size of the energy density of the spot has a great influence on the bending angle and the microstructure and properties of the material. Increase the energy density, sheet bending angle increased significantly. For a material, there is always a set of specific process parameters (beam output power, scanning speed, spot size, etc.) to maximize the sheet bending angle. Moreover, by reasonably controlling the energy density of the spot, the microstructure and properties of the material in the deformation zone can be significantly improved
