Abstract
Grinding is an abrasive machining process generally applied to guarantee a combination of good surface finishing and tight tolerances to the machined surface or component. Besides the cutting parameters, the grinding wheel topography plays an important role in the final conditions of ground surface and, therefore the dressing operation is crucial to the process. In this context, this work aims to analyze the grinding of Inconel 718 under different cutting conditions of work piece speed and depth of cut, using a conventional SiC grinding wheel dressed with two different dressers: single point and fliesen. The output parameters analyzed in this work were the surface roughness (Ra parameter), the electric power consumed during grinding, and scanning electron microscope (SEM) images of machined surfaces. The results showed that although the surface roughness, electric power and SEM images presented the expected behavior related to the variation in workpiece speed and depth of cut, the dresser type showed no significant effect on the results and, therefore, the difference between them is related only to the dressing time, which is about 70%lower using the fliesen one.
