The plastic flow of metal adjacent to the chip-tool interface is analyzed using a mechanical equation of state, which relates the variables stress, strain, strain rate, and temperature. Expressions are derived for the temperature at points within the thin plastic layer. The assumptions, which are similar to those used in the theory of viscous boundary layers, include the hypothesis that the shear stress is constant throughout the layer.
