Analysis of geometric variation in wire EDM machining, varying the height of the material to be cut

In the globalized world competition becomes increasingly between industries. These then seek to innovate and continuously improve, employing knowledge and technology in the development of manufacturing processes increasingly more efficient to produce high quality products at lower costs. In this industrial scenario, machining processes are widely used in metalmechanics and, through these processes, the non-conventional machining by wire electroseration highlights, recognized as a high precision process. However, your geometric deviations may define the service life of a piece or assembly. This article presents an exploratory study on geometric deviations of planicity and rugosity. In wire electroerosion machining in parts of different heights. The results show that there is an influence of the height of the piece and the number of passes in the analyzed geometric tolerances, which is important data at the time of defining the project or the process of a part or assembly.
