The paper is concerned with qualitative analysis of a non-linear model describing the vibrations in cutting processes. The model of the regenerative turning process is described by two delay differential equations. The influence of selected parameters such as the rotational velocity and the frequency of the kinematic excitations as well as the cutting speed and the cutting resistance on the character and level of vibrations is studied. The possibility of the excitation of quasi-periodic or chaotic oscillations for some values of the parameters has been shown. Zones of the sub-harmonic, quasi-periodic and chaotic vibrations were estimated by the methods of numerical integration. Bifurcation diagrams have been used to explain the phenomenon of vibration synchronization. Different types of vibration are illustrated by plots of time histories, phase and stroboscopic portraits.
