The chattering in the machine tools is a phenomenon that causes instability in the machining process, surface finish with high roughness, also produces excessive and accelerated wear on the tool in the metal cutting processes, this phenomenon consists of self-excited vibrations which are produced and maintained due to the cutting forces, the purpose of this article is to analyze regenerative chatter and predict the optimal points of operation in the turning process for 1020 carbon steel by developing analytical methods for generating stability lobe diagrams. To achieve this objective, the methods proposed by Altinas and Budak to stabilize the self-excited vibrations in the turning process applied to the orthogonal cut were studied in detail. These methods are widely accepted within the community of researchers and specialists in the field, thanks to the excellent results obtained in practice. Once the models studied were compressed, a computational algorithm was developed with the help of the MATLAB® software that was able to generate stability lobe diagrams for the turning operation in order to find the optimal points of operation so that there was no chatter, thus improving the material removal rate and increasing productivity
