In this study numerical simulations were carried out to clarify the behavior of regenerative chatter vibrations on a conditional stability limit. After the results of simulations were analyzed, the following conclusions were reached. (1) Regenerative chatter occurring under the condition of a conditional stability limit beats at the rotational speed where the conditional stability limit reaches a maximum, but it does not beat at other speeds, (2) regenerative chatter under an unstable condition near the stability limit grows monotonically at the speed where the conditional limit is equal to the unconditional limit, but it beats growingly at the speed where the conditional limit is larger than the unconditional limit, and (3) the beat whose period is almost equal to the time needed for one revolution of a workpiece is caused by discontinuity of the frequency transfer function of the inner modulation to the outer modulation.
