Abstract
A simulation model for three dimensional finite element method (3D FEM) of thread rolling is presented to investigate the deformation behavior for material, the stress and strain distributions during the thread rolling, and also the residual stress distribution after rolling. In the simulation, metal rod is used 2-roller dies thread rolling machine. Because of the large deformation of thread roots, fine meshes should be used these positions. The simulation results of thread rolling show the similar deformation behavior observed in the practical thread rolling and provide residual stress and plastic strain distribution.
