Abstract：

In order to effectively control the deformation of single-point incremental forming for metal sheet,its forming deformation mechanism was analyzed and some effective measures to control deformation were put forward.The deformation caused by the following forming force was effectively controlled by the nailing limit method.The complete plastic forming in small curvature area was realized using partial rigid support structure.The sheet metal spring-back was reduced by forming structure optimization.The surface spring-back on flat surface was controlled using work-harden principle.The structure distortion of petronas doublet was effectively controlled by programming with the accordant layered forming method.These measures were proved that it is effcetive and reliable in production. It can be widely applied in sheet metal single-point incremental forming process and actual production.
