The design of the blank layout is an important part of progressive die designing and controlling the forming sequence of the parts is the key process. According to the structure of leading arc flake, the blank layout for progressive die was designed with different datum planes. The forming stress of leading arc flake was analyzed with finite elements method. The structure of leading arc flake in different blank layouts was compared. The rational blank layout was summarized and the forming progressive die was designed under the condition. The forming progressive controlled the material fluxion as leading arc flake was formed availably. The forming shape of the work piece was full and level. The quality of products was assured.
