We investigate the effect of drawing conditions on the drawn diameter in cold wire drawing by Finite Element Method. The mechanism of diameter variation was elucidated including the elastic deformation of the die, undershoot, diameter thickening during drawing and unloading springback. Undershoot was caused by the separation of the bar from the die at the beginning of the bearing zone during drawing, and it was the main reason for the variation in the drawn diameter. The undershoot was induced by the plastic deformation at the surface of the bar. We considered that it is caused by the tensile virtual residual stress and drawing stress at the surface of the bar in the axial direction. Thus, applying a low-approach semiangle to reduce the diameter of the second die is an effective method to reduce the diameter variation in tandem pass drawing.
