Among the factors that influence the performance of mechanical components, stand the material and surface conditions. During the machining process, the surface generated can be altered, which have influence on the properties of the material. Due to the variety of machining processes, it is necessary to evaluate the different processes in order to select the most appropriate for each manufacturing operation. Thus, the goal of this work was to evaluate the influence of different processes in the integrity of the generated surface using two conventional processes: drilling and milling, and one unconventional: electrical discharge machining (EDM). In drilling and milling tests were used carbide tools, and in EDM was used a copper electrode. The machined material was ABNT 1045 steel. The results showed bigger changes in the surface generated by the EDM process than those caused by the conventional processes.
Key words: drilling, milling, EDM, properties of materials, process selection.Downloads
