| Metalworking fluids have an exceptional role in grinding. Correct fluid application results in enhanced process stability, better work piece quality and tool life. This works aims to create and use Computational Fluid Dynamics (CFD) models in order to simulate the fluid flow and heat transfer in a grinding process, as a better alternative to many experiments that are expensive, time-consuming and with very limited ability. The features of created 2-D and 3-D models are described in detail, along with results obtained, and proposals for the future work. The results show very detailed distributions of temperatures, pressures and flow rates in and around the grinding region. By generating a very detailed picture of the grinding process itself, the data obtained is essential in studying the influence of the grinding fluid on the grinding process, as well as in determining the best fluid composition and supply parameters for a given application. The results agree well with experimental global flow rates and temperature values and show the feasibility of both 2-D and 3-D simulations in grinding applications, and performed parametric studies can be an useful tool in optimizing grinding processes. |
