The heat conduction problem of sliding contact as found in a tool work-piece interaction is analyzed by assuming the presence of a thin boundary layer between the tool wear-flat and the work-piece. Within the layer heat is produced at a constant rate per unit volume of the layer material as a result of large frictional forces. The layer material itself constitutes in the case of cutting of a brittle material a very fine powder whose thermal properties may differ significantly from those of the tool and the work-piece. The presence of the boundary layer permits thus the tool and the work-piece surface temperature distributions to be totally different Furthermore, the evolution in time of these distributions is determined by the heat conduction characteristics of the entire system under consideration and consisting of tool, layer and work-piece. The mathematical formulation of the problem results in a mixed boundary value problem which can be recast into a pair of coupled integral equations of the Fredholm type for the unknown heat source distributions over the tool and work-piece wear-flat area. The resulting tool wear-flat surface temperature distribution is shown to depend on the boundary layer thickness and thermal properties to a significant extent. The heat source distribution obtained for a set of given parameter combinations may serve as a prime input quantity in e.g. a finite element program designed to calculate the entire tool temperature distribution as a function of time.
