In this paper, the residual stress after the sparkout grinding are experimentally analysed to investigate the final distribution pattern of residual stress in the ground part and the characterizing factors of the distribution of residual stress. The distribution pattern after the sparkout grinding is C-type under any grinding conditions, while the distribution patterns in the steady grinding are classified into three types, depending on grinding conditions. The depth of stressed layer after the sparkout grinding is smaller than that in steady state and has close relation to the product Lc·tmax. Further, the maximum compressive stress, characterizing C-type distribution, is affected by the ratio Lc·tmax/f.
