In order to provide technical supports for designing a new type spiral plate forming machine, a three dimensional finite element method (FEM) model was built by using a FEM software (MSC.Marc) based on pressing tests. Deformation, stress distribution, residual stress and spring back of the spiral plate were calculated, and the relationships between the spiral pitch and the inclination angle of the punch and die, material properties and thickness of the plate were analyzed. A data converter from I-DEAS to MSC.Marc was developed and effectively used in the analysis. The results of FEM analysis and simulation have been applied to design the spiral plate forming machines.
