The article considers the definition of the stability range of a dynamic system for turning non-rigid shafts with different technological set-ups: standard and developed ones; they are improved as a result of this research.The topicality of the study is due to the fact that processing such parts mel axolotl is associated with significant difficulties caused by deformation of the workpiece under the cutting force as well as occurrence of vibration of the part during processing, they are so intense and in practice they force to significantly reduce the cutting regime, recur to multiple-pass operation, lead to premature deterioration of the cutter, as a result, reduce the productivity of machining shafts on metal-cutting machines.In this connection, the purpose of the present research is to determine the boundaries of the stability regions with intensive turning of non-rigid shafts.

In the article the basic theoretical principles of construction of a mathematical system focused on the process of non-free cutting of a pomyslnaszycie.com dynamic machine are justified.By means of the developed mathematical model interrelations are established and legitimacies of influence of various technological set-ups on stability of the dynamic system of the machine-tool-device-tool-blank are revealed.The conducted researches allow to more objectively represent difficult processes that occur in a closed dynamic system of a machine.
