Assessing the Regenerative Effect Impact on the Dynamics of Deformation Movements of the Tool during Turning

摘要

The article is devoted to the modeling of the deformation movements of the tool during turning. Despite the fact that these studies have already been carried out, the issue of assessing the impact of regenerative fluctuations on the trajectory of the formative movements when turning has not been studied yet. The article gives a mathematical model and the results of numerical modeling of deformation shifts during the cutting process. It is shown that under certain conditions, depending on the parameters of the reformative system of a machine, the trail left by the tool during the previous turn, can not only be transferred to the next turn, but also increase. In this case, the phase difference of the regenerative oscillations and current deformation oscillations of the tools may not lead to the stabilization or damping of oscillatory processes.
