Resumo(s)
Nowadays, additive manufacturing is considered an important propeller for a new industrial revolution. The recent advances in this manufacturing approach show that Wire and arc additive manufacturing (WAAM) has the potential to become a relevant method for the production of metallic components on a large scale. In this study, the need for the post-processing of these parts was recognized, which led to the characterization of the milling process regarding the several properties inherent to these parts.
The thin-walled structures required for the milling operations were manufactured using two different heat inputs. Then, a milling strategy that has in consideration the characteristics of such components was applied, where the process parameters and the tools utilized during the experiments were chosen based on the information provided by the tool manufacturer.
The results show that the properties inherent to the components manufactured via WAAM have influence in the milling process and that the quality of the surfaces improves with the increase of cutting speeds and with the decrease of feed per tooth. Nevertheless, more investigation is required to accurately study the milling process on WAAM parts due to the tool wear mechanisms associated with the workpiece material
