The drawing process of steel bars is usually used to check better dimensional accuracy and mechanical properties\udto the material. In the other hand, the major concern found in manufacturing axes through this process is the appearance\udof distortion of shape. Such distortions are directly linked to the accumulation of residual stresses generated during the\udprocesses. As a result, this paper aims to study the influence of process parameters such as shape of puller, speed and\udlubrication used in wire drawing analyzing the accumulation of residual stress after the process. The stress analysis was\udperformed by FEM being used two simulation software: Simufact.formingGP and DeformTM. Through these analyzes, it\udwas found that the shape of how the bar is pulled causes a reduction of up to 100 MPa in residual stresses in the center\udof the bar, which represents an important factor in the study of the possible causes of the distortion. As well as factors\udspeed and homogeneity of lubrication significantly altered the profile of residual stresses in the bar
