• The stability criterion for the grinding system has been analyzed by the help of frequency response method. However, this analysis shows only whether the system is stable or not in the steady state and so the experimental fact that the self-excited chatter vibration in grinding grows up gradually is not verified yet. In the present paper, it is shown first that even the system in an unstable region according to the old stability criterion is stable at the beginning of grinding until the primary waviness coincident with the chatter frequency is formed to a certain level by disturbance ; second, that the waviness growing up process revealed by translating the system from the frequency domain to the time domain can be described by a series of the rates of dynamic cutting residue ; and finally that the vibration is kept to a steady amplitude if it grows uo to the level where the regenerative effect decreases due to a non-contact of wheel with work.
