The fracture is primary drawback to stability of production in the drawing of complex-shaped parts. In the paper, the fracture of complex-shaped part drawing is investigated experimentally and numerically. A grid method is adopted to analyze the deformation character, deformation path, deformation degree and safety margin in risk region where is determined by numerical simulation and experiment. The magnitude of safety margin and the stability of production are greatly increased by optimizing the height of draw-bead and the blank size.
