Abstract
The machining of parts using machine tools has undergone many developments over the last few decades. The first machines had low cutting speed, considering that mechatronics had limitations. However, with advances in mechatronics and information technology, these machines can now operate at much higher speeds. In this context, the cutting speeds had a great increase. This change allowed complex machining. This additional potential made it possible to work on a major problem when machining parts with elaborate geometry and thin thickness. This study grows in importance for the manufacture of parts in which warping compromises the functional performance, such as parts of aircraft wing control surface. In this article, we intend to characterize the machining strategy, evaluating machining parameters such as depth, cutting speed and cutting width. The methodology used is the machining of specimens using combinations of relevant cutting parameters with the subsequent evaluation and characterization of geometric and dimensional changes. At the end, a conclusion will be presented with a list of cutting parameters on the influence on residual stress and final warping.
