Rotary swaging process of a tube was simulated using finite element method. The diameter of the tube was 2 mm and the thickness was 0.35 mm and the length was 10 mm. Rotation rate of the dies was 545 rpm and the feed rate was 20 mm/min. It is found that the hydrostatic stress of the workpiece at the surface became tensile state and The circumferential stress became large. The hydrostatic stressin the cross-section became also tensile state. Circumference stress and axial stress were also large.
