Analytic solution for maximum temperature during cut in and cut out in surface dry grinding

Considering the Samara-Valencia model for heat transfer in surface dry grinding, analytical expressions are calculated for the time-dependent temperature field of the workpiece during the transient regime in which the wheel is engaged and disengaged from the workpiece. For this calculation, a linear heat flux profile along the contact zone between the wheel and the workpiece has been considered. From these results, a very rapid method is described for the numerical evaluation of maximum temperature at the initial and final workpiece edges. This analytical result is intended to be a very useful tool for the monitoring of the online grinding process in order to avoid the thermal damage of the workpiece.
