The investigators use primarily methods based on the mathematic simulation of the dynamic systems. Some problems of the nonlinear dynamics of the material cutting are considered. A mathematical model of the dynamic system considering the dynamic link formed by the cutting process is offered. Here, the following key features of the dynamic coupling are taken into account: dependence of the cutting forces on the area of a cut-off layer, delay of forces towards the elastic deformation shifts of the tool in relation to the workpiece, restrictions imposed on the tool movements when the back of the instrument is approaching the treated part of the workpiece, forces - cutting velocity relation. The dynamic subsystem of the tool is presented by a linear dynamic system in the plane orthogonal to a cutting surface. Following the research, some guidelines for designing systems with the required stationary manifold in the state space are provided. Importantly, in the neighborhood of equilibrium, various criteria of set causing regular or irregular features of the formed in-cut surface can develop depending on the models interacting under processing.</p></abstract><trans-abstract xml:lang="ru"><p>Рассмотрены проблемы нелинейной динамики процесса обработки материалов резанием. Предложена математическая модель динамической системы, учитывающая динамическую связь, формируемую процессом резания. Динамическая подсистема инструмента представлена линейной динамической системой в плоскости, нормальной к поверхности резания. На основе выполненных исследований даются рекомендации по проектированию систем, имеющих требуемые стационарные многообразия в пространстве состояния. Полученные данные позволяют сделать следующие выводы. Динамическая система резания может служить примером сложного поведения, зависящего от параметров подсистемы инструмента и представления сил в координатах состояния. Представление сил в координатах состояния зависит от множества физических процессов, сопровождающих обработку. Важно отметить, что в зависимости от моделей, взаимодействующих через процесс обработки, в окрестности равновесия могут формироваться различные критерии множества, вызывающие регулярные или нерегулярные свойства формируемой при резании поверхности . </p></trans-abstract><kwd-group xml:lang="ru"><kwd>процесс резания материалов</kwd><kwd>динамическая система</kwd><kwd>инвариантные многообразия</kwd><kwd>бифуркации</kwd><kwd>materials cutting</kwd><kwd>dynamic system</kwd><kwd>invariant manifold</kwd><kwd>bifurcations</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дроздов, Н.
