ABSTRACT
In the current production market, more and more important it becomes to evaluate the manufacturing process as a whole. Taking into account that each step in a manufacturing route will have some influence on the final product, the knowledge of different effects can minimize production losses. The present work aims to characterize the effects of the shear cutting method used in a combined drawing process chain of AISI 1045 steel bars. With a better understanding of the effects caused by this type of cut during the process, it will be possible to assess the necessity of the removal from the bar's end in order to obtain a more homogeneous billet for forging. The characterization was performed through microstructural, microhardness and residual stress analysis. The residual stress measurement was carried out with the use of X-Ray Diffraction (XRD) technique. The result shows that the effect of the cutting goes beyond of grain deformations and hardness enhancement of the cut surface. Residual stress profiles presented differences up to 30 mm of distance from the cut surface.
