Abstract
The article presents the results of experimental studies of noise and vibration spectra that occur in gear-shaping machines during their industrial operation under various process loads. Depending on the technical parameters specifications of these machines, during the execution of work according to the process regulations, the sources that create increased noise levels are identified, namely the cutter and the workpiece, while the influence of the frame can be ignored. This is confirmed by theoretical conclusions about the patterns of formation of vibroacoustic characteristics of gear-shaping machines. Based on the conducted studies, it was possible to identify the key factors that affect the magnitude of noise and vibration in gear-shaping machines. First of all, these are the design features of the cutter and the workpiece material. Various geometric parameters of the cutter, such as sharpening angle, shape and degree of sharpening, significantly change the pattern of vibration distribution during the cutting process. Moreover, materials with a higher modulus of elasticity and density contribute to an increase in the overall vibration amplitude, which is reflected in the noise spectrum.
