“…The fourth section includes a parametric study of the process, varying the velocity of the workpiece and the duration time of a cycle which includes the contact of the grinding wheel with the workpiece, the cooling of the workpiece surface by interaction with a grinding fluid and the transit of a gap between the wheel and the workpiece along the band of contact. As an example, optimal values of the parameters are given for the particular case of a titanium alloy VT20 workpiece [10] being grounded by an intermittent grinding wheel.…”

We have considered the analytical solutions for heat transfer in wet flat grinding, assuming a linear and a constant heat flux profile, entering into the workpiece. We assume as well a constant heat transfer coefficient for the coolant acting on the workpiece surface. In order to avoid thermal damage, we provide a very fast method for the computation of the maximum temperature, which occurs on the workpiece surface in the stationary regime. We also provide a very rapid method for the numerical evaluation of the transient regime duration (relaxation time). By knowing the location of the maximum temperature and the relaxation time, we have performed an analysis for the computation optimization of the temperature evolution on the workpiece surface. This kind of analysis offers a very interesting simulation tool to avoid thermal damage during the transient regime.

“…Data set 1 considers a carbon steel workpiece AISI 1020 [21] and data set 2 considers aluminum oxide, Al 2 O 3 (sapphire), as workpiece material [22]. Also, data set 3 considers a titanium alloy VT20 workpiece, whose thermal properties are given in [23]. The grinding regime for this simulation can be found in [24].…”

In the framework of Jaeger's model for heat transfer in dry surface grinding, series expansions for calculating the temperature field, assuming constant, linear, triangular, and parabolic heat flux profiles entering into the workpiece, are derived. The numerical evaluation of these series is considerably faster than the numerical integration of Jaeger's formula and as accurate as the latter. Also, considering a constant heat flux profile, a numerical procedure is proposed for the computation of the maximum temperature as a function of the Peclet number and the depth below the surface. This numerical procedure has been used to evaluate the accuracy of Takazawa's approximation.
