Vibrations during a cuttting process are analysed by means of a frictional and a regenerative model. For this purpose a new model which contains a nonlinear friction force, defined by Rayleigh's self-excitation, is developed. Then a one degree of freedom model is examined using analytical and numerical methods. The regenerative model of cutting is separately examined in order to emphasize differences between frictional and regenerative models. Next, a mutual interaction of frictional and regenerative effects is discussed and their influence on process stability is shown. Finally, a two degree of freedom frictional model with an extra centrifugal force is investigated. Various kinds of behaviour, from regular to chaotic are shown.
