Abstract
An atomic approach to chip deformation and failure in cutting is outlined. The relation of the shear strength and the type of chip to the energy characteristics of the crystal lattice, its packing-defect energy, and the latent heat of fusion is established. The constancy of the shear with variation in the cutting conditions is related to the limiting dislocation density and the formation of an amorphous–liquid state.
