Frequency Analysis of Noise at different Milling Parameters of Steel

Abstract

The aim of this paper was to experimentally analyse dependency between level of noise in octave band at various standardized central frequencies (31.5, 63, 125, 250, 500,…, 16000 Hz) and different cutting parameters of milling. Based on data from our previous research we analyzed dependency between level of noise in octave band, at standard frequency 500 Hz, and axial and radial depth of cut. In Design-Expert® software we have found adequate models and equations that describes these dependencies. The experimental results obtained can be used for future investigations in this field.
