An analysis of the transient regime temperature field in wet grinding

Abstract

In this paper, the Samara–Valencia model for heat transfer in grinding is considered. This model is particularized to the case of wet grinding, assuming a constant heat transfer coefficient on the workpiece surface and a constant heat flux profile entering into the workpiece, obtaining a solution for the temperature field in the transient regime. Performing the limit $$t\rightarrow \infty $$ in this solution we get a formula analytically equivalent to the well-known solution given by DesRuisseaux for the steady-state temperature field. Also, we derive for the transient regime very simple formulas for relaxation times in wet and dry grinding.
