Abstract
The results of a comprehensive study of the hobbing process dynamic parameters based on interrelated models are given in the article. The elastic cutting system is the first component of this system. Parameters of the elastic system are determined based on the simulation of the thickness and sectional area of the cutting cross-sections and by the analysis of the transient process of forming the cutting force in the system Deform 3D. The second component of the model includes the description of oscillating processes in the circuits of the hob and the workpiece of the toothed wheel. The method of experimental determination of the dynamic parameters of this system and the determination of its amplitude-phase frequency response is described. The equivalent elastic system and the own frequencies of the most powerful oscillations of the machine elements are analyzed. The behavior of the closed system of the machine with the cutting process under the influence of changing the cutting parameters (feed and cutting speed) is simulated in the Simulink MATLAB system. On the basis of this, the optimal cutting modes and parameters according to the criterion of ensuring the required stability of the tool machine during the hobbing can be appointed.
