Abstract
In the search for robust mechanical properties, it is obligatory to impose the parts at specific mechanical, chemical or thermal requests. Given the above, considering that the all manufacturing process includes residual stresses, the bigger the number of operations required, the bigger the probability of dimensional distortion in the component. Thus, in order to reduce the occurrence of dimensional distortions in excess of tolerance, it was sought to identify the most critical stage and, therefore, to act with feasible possibilities and without relevant costs to prevent the problem found. In order to measure its residual stress and define the process in which the higher inclusion of traction residual stress, which are the deleterious ones for the process and for the product, the X-ray diffraction residual stress measurement method was used. The stresses included on the surface of the specimens were measured at specific stages of the process. In this sense, it was possible to determine that the most careful operation related to the component request is the machining in which it is applied. The subsequent processes only aggravate this condition, resulting in an unusable component for the proposed application without the inclusion of rework or scrap procedures.
