Abstract: When the elements of the friction couple (chip and cutting tool) are in contact, at the sliding interface, the materials are dissolved if the free energy of a new formatted material decreases during the solution formation. The dissolution speed increase with the growth of the interface temperature. The dissolved material is transported through diffusion into the chip. Through the remove of the dissolved material, it is formatted the "cone" to the rank face of the cutting tool. The chemical instability is the main reason for dissolution of the materials which are part of the friction couple. The energy generated by  friction in the contact area contributes to modify the thermal regime and to amplify the phenomena of the diffusive transportation.
