In cutting with a tipped saw, the dynamic stability is affected by cutting thermal stress. In this study, the relationship between thermal stress and dynamic stability, and the tensioning effect were investigated analytically and experimentally using normal and tensioning disks. The following conclusions were reached. (1) Natural frequencies of more than second vibration modes decrease with the temperature difference between flange and peripheral. (2) Critical speed and buckling temperature are increased by tensioning. (3) With the temperature difference until buckling, transfer function of more than second vibration modes increases, and the dynamic stability decreases. This tendency is improved by tensioning. (4) In the region of postbuckling, natural frequencies of each vibration mode were examined.
