Abstract

Based on the flexibility of multipoint forming, a work piece can be formed in a way section by section, which is named sectional multipoint forming (SMPF) here. With this technique, large-size parts of sheet metal can be manufactured on a small MPF press. In this article, basic principles and deformation characteristics of SMPF are discussed and three typical forming methods are summarized. Partial severe plastic deformation has become the main defect needed to be and wrinkle and dimple have new features in the SMPF process. Numerical simulation is an effective way to predict forming defects. Optimized design of the assortative region can suppress forming defects and improve forming efficiency. Some application examples improved the feasibility of SMPF technology .
