Abstract: This study presented a study on calculation of residual stress on the surface layer of workpiece when grinding AISI 1018 steel. Johnson-Cook’s material model has been applied to build a relationship between residual stress on the surface layer and the parameters of the machining process. This relationship was used to calculate the values of residual stress when grinding. The calculated results of residual stress were compared with the experimental results. The results showed that the residual stress values when calculating were quite close to the values from experimental works. The average deviation between the calculated results and the experimental results is only about 15.96%. The results of this study offer a promising method for calculation residual stresses on surface layer when grinding AISI1018 steel.
