Contact deformation characteristics of grinding and regulating wheels are found to have stabilization effect on self-excited chatter vibrations. A new model of centerless grinding system including the effect is proposed. Characteristic equation of the model is analyzed using diagrammatical coincidence method and growing rate of chatter vibration can be quantitatively studied. Furtheremore, concept of root-locus method is introduced and distribution loci of characteristic roots corresponding to various grinding conditions are derived. And rounding effect criterion diagram representing generalized growing mechanism of chatter vibration is newly proposed. Applying this new diagram, it becomes possible to specify stable grinding domain and set up stable grinding operations. Also the diagram can give guide lines of wheel selection and design specification of centerless grinding machine in viewpoint of strategies for stabilization of chatter vibration.
