The invention belongs to the technical field of metal sheet laser bending forming, and relates to an energy regulation and control method for reducing the bending amount of a metal sheet laser bendingforming. In the invention, a method combining three-stage variable speed with local energy compensation is adopted for correcting a warping deformation, and the energy coarse adjustment is carried out by adopting a three-section variable speed mode to adopt a low speed to ensure higher energy input at the section position with small bending angle and high bending angle adopting high speed to ensure lower energy input; the energy compensation method comprises the following steps of: carrying out energy compensation on a segment position with small bending angle by scanning a local area with small bending angle for lesser times after the local energy compensation mode is processed; and the combination of the two aspects can effectively reduce the bending amount in the laser bending processof the metal sheet and meet the technical requirements. The method can be applied to the field of metal sheet forming with high angle precision required by laser non-die bending processing.
