In modern production, despite the existence of other production methods, metal cutting still plays an important role. The performance of machine tools has a decisive role in terms of productivity and quality of production increase. When it comes to improving the performance of machine tools, the analysis of the appearance of self-excited vibrations and their isolation occupy a significant place. The aim of this paper is derived from trends and limitations present in metal production. The paper presents two popular analytical methods for identifying stability lobe diagrams in milling, and compare them with stability lobe diagram obtained experimentally. The influence of certain regime on the occurrence of self-excited vibrations, i.e. the definition of vibrational stable processing regimes, is considered.
