Abstract: Since grinding is often the last process of a manufactured part, caution has to be taken in order to ensure the integrity of the ground surface. Many authors have shown that in a few cases temperature can be very high and therefore can induce phase transformations. Thus, the best way to ensure the quality of the ground surfaces is to predict the apparition of these phases. This paper shows that numerical simulations of phases during grinding are possible and they gives good predictions of phases. An example using AISI 52100 bearing steel material for the workpiece and a triangular heat flux model is presented. The model of simulation is explained and results are detailed.
