The outside of a workpiece like a disk is turned and orthogonally cut with a cutting-off tool fed by the cross spindle of a lathe, and the workpiece is assumed to be a system with two degrees of freedom. Numerical calculations of the equations of motion for regenerative chatter and also cutting tests are carried out. As a results, it is shown that the regenerative chatter is initially caused by a small disturbance, it can be classified by a width of cut into disappearance, constant amplitude and growing amplitude. 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 whether the chatter disappears or grows in its amplitude is determined fairly by the stability criterion.
