FEM Simulation and Analysis of Temperature Field of Environmental Friendly MQL Grinding

Abstract

Abstract:This study proposes an approach for the development of a three dimensional transient heat conduction finite element model (FEM) for grinding process. FEM simulates the temperature field in conventional and nanofluid based environmental friendly minimum quantity lubrication (MQL) grinding process. For this FEM simulation the boundary conditions were obtained on the basis of results of the heat transfer on semi-infinite object with a heat source moving along its surface. Instrumented surface grinding machine was used for experimental purpose. Lubricant used for MQL system was water based nanofluids of various concentrations. Nanoparticles of CuO and Al 2 O 3 were used for preparation of nanofluids. Grinding performance was measured in terms of workpiece surface temperature and cutting force. This model can be used to predict the cooling effectiveness of various lubrication systems. Analysis shows that the FEM temperature values matches with the experimental temperature data.
