The orthogonal dry cutting of commercial pure aluminium plates was made to study the effect of cutting conditions on residual stress distributions in the cut surface, and the plastic strain in the cut surface was measured by the Moire method for the specimens with different cutting conditions and with sudden stop of cutting. As the results: the residual stresses by cutting are apt to be tensile in the surface and to be compressive in the inner part, and the Moire strain in the cut surface is

On the other hand, at the cutting, the large strain of plastic tension is produced in the portions in front of the cutting edge of the tool. This primary strain and the secondary plastic deformation due to the progression of cutting edge strongly influence the residual stress.
