| description | The conditions under which the chaotic dynamics is formed during the materials processing by cutting are analyzed. In the previous studies, in case of loss of sta-bility of the cutting process, limit cycles or invariant tori are generated in the neighborhood of the equilibrium system. Contrastingly to these studies, the case when the tool properties are such that a nonlinear positive feed-back is formed by flexural deformations is considered. A mathematical system model is provided for this case. On the basis of the numerical simulation, using the MATLAB application program package, the dynamic model parameters effect is explored under the conditions of the chaotic dynamics formation. The research results show that with increasing the parameters characterizing the formation of a positive feedback, the system undergoes a series of period-doubling bifurcations in the system of strange attractors. They are located in the vicinity of the equilibrium points and have a limited area. It is shown that the tool chaotic oscillations lead to the chaotic work surface forming, therefore, in the application sector, it is necessary to choose the parameters under which the chaotic dynamics is not formed. Although the considered examples relate to the cutting process, the obtained results are of general validity for the dynamic systems interacting with various environments, for example, with a tribological environment. |
