The stability criterion derived by mathematical models of the machine tool vibratory system and the dynamic cutting process predicts cutting conditions under which the machine tool working against chatter develops dynamic instability. In this study, we assume that a turning workpiece has directional vibratory properties, and derive both its unconditional and conditional stability criteria, including the effect of velocity components of dynamic cutting forces. In view of the importance of designing machine tools with high dynamic stability and eliminating chatter in the shop, it is necessary to investigate the variation of the stability limit caused by the velocity component in relation to the directional vibratory properties of the workpiece. As a result of the investigation, it is revealed that the stability limit variation caused by the velocity components depends to a considerable degree on the principal coordinate direction of the workpiece vibratory system.
