The authors have proposed a generalized centerless grinding defined for four modes of combinations of set-up conditions of positive or negative center-height angle and positive or negative work-piece revolution in spinning directions. The rounding mechanism of the generalized centerless grinding has been analyzed in general and derived the generalized rounding effect criterion diagram. But in the previous papers, focusing a dynamic stability of rounding effect, the top angle of work support blade was not taken into analysis considering less effect in comparison with the center-height angle and the work speed in revolution. Therefore, geometrical/statical stability in rounding effect was out of analysis. In this paper, an effect of the top angle of work support blade is taken into analysis as well as the effect of the center-height angle and work speed in revolution. And both geometrical/statical stability and dynamic stability can be analyzed quantitatively by solving characteristic root using vector locus coincidence method. In viewpoint of geometrical/statical stability, it is also clarified from this analysis that the rounding effect of positive center-height angle modes is more stable than that of negative center-height angle modes.
