Computer simulation of dynamic processes in power skiving gear cutting

The paper presents the results of simulation of the dynamic processes during gear cutting using the power skiving method. Oscillations in the elastic system of the machine tool have been studied using the Simulink Matlab system. The closed dynamic system is represented as a series-coupled connection of the elastic system of the cutting process and the elastic system of the machine tool, which is assumed to be two-mass, with masses applied to the table assembly with the workpiece and to the tool spindle. The input signals of the cutting process system – the thickness of a single tooth cut and the total chip thickness in continuous cutting – are modeled on the basis of a previously developed computer modeling system for this process. It is shown that the combination of these systems makes it possible to select the maximum permissible values of the cutting conditions that satisfy the condition of stable operation of the machine tool and maximum reduction of machining time.
