Centerless grinding is characterized by supporting a workpiece with the periphery to be ground under a preliminary selected geometrical arrangement and in viewpoint of rounding action there exist geometrical/statical stability and also a dynamic stability in the grinding system. Work set-up conditions such as center-height angle, work speed in revolution and top angle of work support blade dominate the stability of rounding action. Therefore, for selecting the optimum work set-up conditions for stability, it is necessary to prepare a practical guideline to enable to satisfy both the geometrical/statical stability and also the dynamic stability simultaneously. In the present paper, an identification method for the dynamic stability conditions and also a method of integration of the geometrical/statical stability with dynamic one are proposed. Application of the proposed method enables to give a practical guideline to select the optimum work set-up conditions.
