• The outside of a dislike workpiece is turned and orthogonally cut with a cutting-off tool fed by the cross spindle of a lathe, and the workpiece is assumed to have a linear vibratory system with two degrees of freedom. Numerical calculations of the equations of motion for regenerative chatter, as well as cutting tests, are carried out. As a result, the regenerative chatter is shown to be initially caused by a small disturbance and classifiable into disappearance, constant amplitude and growing amplitude by different widths of cut. Further, the behavior of chatter is compared with the stability criterion that is given by a set of harmonic solutions of the equations for regenerative chatter, and it is verified that whether the chatter disappears or grows in its amplitude is determined by the stability criterion.
