Abstract

Introduction. The analysis of the research papers shows the relevance of this topic, since there are no publications devoted to the determination of the spectral components of the power sequence of the milling process which makes it difficult to analyze models of the noise and vibration excitation. The noise exposure limits excess due to the high tool speed presents a critical problem. The highest speed is observed when the copy milling machines are operated. In the cutting conditions standards, only the power action amplitude is specified for woodworking which makes it difficult to determine the noise spectra. This study is devoted to determining parameters of the power sequence arising under the circular moulding. Materials and Methods. Methods of the cutting theory, spectral analysis, and statistical processing are used in the course of this study. Techniques of the noise and vibration levels analysis are largely determined by specifying the power action as a time function. Research Results. As a result of the conducted research, the mechanism of the force generation under milling; rules of the forces distribution over the projections; and patterns of variation in the cut-off allowance under milling are determined and specified. Discussion and Conclusions. The constructed mathematical model of the milling process dynamics and the software developed on its basis make it possible to evaluate the sound pressure levels created by both the cutting tool and the spindle case. This sound pressure actually determines the excess of noise levels over the maximum permissible values.
