| Abstract | |
In grinding operations, dressing tools are of major importance, since they are responsible for the topography of the wheel working surface and, consequently, can affect the grinding results in terms of surface integrity, dimensional accuracy and process reliability. Therefore, as an important part of the grinding operation, dressing can significantly improve the quality of ground parts if better dressing tools are produced. This work studies the main needs for designing sintered dressing tools made with constant cross sectional synthetic diamonds. It also analyses the temperature distribution over a novel dressing tool design using experimental measurements to feed computacional simulation by the finite element method (FEM). The temperature model employed showed some limitations but the obtained results indicated that temperature levels over the dressing tool were affected by the dressing parameters considered in this work, namely the dressing depth of cut (\'a IND. d\'), the dressing overlapping parameter (\'U IND. d\') and the flow rate (Q). Additionally, one can say that the dressing tool wear was affected only by the dressing parameters (AU) | |
