The authors measured the residual stresses in various grinding conditions by the methods of strain gauge and X-rays. The plastic strains below the wheel-work contact area of specimens which were taken out from the grinding point during grinding process by a quick stop equipment were also measured. Then, the influences of the plastic strains on the distribution of the residual stress below the ground surface were discussed. As a result, it has been shown that the normal direction strains in the wheel-work contact areas were related to the maximum residual stresses and to the depth of tensile residual stress part in the stress distribution curves.
