Wide applications of tube drawing process with using a fixed conical plug in manufacturing of thin-walled tubes have convinced the researchers to investigate and optimize this process in the past years. Current study deals with presenting an optimum curved die profile utilized in tube drawing process with fixed conical plug. Minimizing the required tensile stress in the process as well as reducing the stress which is applied to the die and plug has been considered as objectives of this study. Considering work-hardening behavior of material, the drawing stress of the process is analyzed based on incremental slab method theory. In addition to, plain strain condition is applied through the thin-walled tube. Furthermore, the obtained optimum die profile has also been simulated using ANSYS Workbench 18.0 and the results were compared with those of analytical method. It is found that the die profile could be determined based on the mechanical properties of the workpiece, reduction of cross section area, plug angle, and coefficients of friction. Results demonstrate that by applying an optimum die profile, the required tension stress in tube drawing process could considerably be reduced comparing to the same process with conical die profile.
