Stagger spinning of tube parts is a very complicated plastic forming process. In real production, spinning defects are produced usually accompanying the production. In this paper, the reason of some typical defects of tube stagger spinning is studied by a method of three dimension elastic\|plastic finite element (FEM) simulation. This will be very helpful in directing the production of spinning parts in theory.
