This study presents experimental findings regarding the influence of phase shift between adjoining waves on the cutting surface and its impact on the intensity of regenerative self-oscillations during continuous cutting without the influence of coordinate coupling. The study was conducted using an original design of a cutter-oscillator with one degree of freedom. The importance of the obtained results lies in the possibility of verifying the fundamental principles of regenerative oscillation theory, presented by developers in the past century, which could not previously be confirmed due to limitations in experimental capabilities. The study revealed the absence of a connection between the magnitude of the remainder from the whole wave and the phase shift of adjoining waves, as well as the absence of influence of these parameters on the intensity of regenerative self-oscillations. These results contradict previously accepted notions and indicate the need to refine theoretical models. However, a significant correlation was found between the frequency of regenerative self-oscillations and the phase shift of adjoining waves. This suggests that vibration during continuous cutting is a self-organizing process. It is noted that the obtained results pertain only to continuous cutting conditions, and further research is planned to expand the investigation to intermittent conditions, such as turning with longitudinal grooves or protrusions, for a more comprehensive understanding of the influence of cutting parameters on oscillation processes. The results of the experimental verification are valuable for optimizing cutting processes to enhance efficiency and processing quality. The article aims to experimentally verify two fundamentally important statements formulated by the developers of the theory of regenerative oscillations for continuous cutting.
