激光高速柔性微成形（LHSFF）工艺因其与传统微成形工艺相比具有独特的优势而被应用于金属板材的成形。到目前为止，LHSFF研究的材料都是单层金属片。然而，由于其优越的性能，在一些工业场合已经开发出新材料来替代单层金属板。本文研究了一种采用 LHSFF 形成多层金属板的新工艺。首先验证了三层Ni/Cu/Ni金属板新工艺的可行性。从实验中可以得到一些结果。成形件出现表面粗糙化现象，且随着激光能量的增加，表面质量变差。随着软冲头厚度的增加，在 LHSFF 下 Ni/Cu/Ni 金属板的成形深度减小。外层厚度减少量和显微硬度增幅均大于中层，中层大于内层。与传统的成形工艺不同，在 LHSFF 下，Ni/Cu/Ni 金属板的成形不再出现分层失败。
Laser high speed flexible micro-forming (LHSFF) process has been applied to the formation of metal sheets due to its unique advantages compared to conventional micro forming processes. The materials investigated in LHSFF were all single-layer metal sheets so far. However, new materials have been developed to replace single-layer metal sheets in some industry occasions because of their superior properties. This paper investigated a new process that employed LHSFF on the formation of multilayer metal sheets. The feasibility of this new process for three-layer Ni/Cu/Ni metal sheets was verified firstly. Some results could be obtained from the experiments. Surface roughening happened in formed components, and surface quality became worse with laser energy increasing. As thickness of soft punch increased, the forming depth of Ni/Cu/Ni metal sheets decreased under LHSFF. The thickness reduction and the amplification of micro-hardness of the external layer were larger than those of the middle layer, and those of the middle layer were larger than in the internal layer. Unlike conventional forming processes, the formation of Ni/Cu/Ni metal sheets did not suffer from delamination failure any more under LHSFF.
