Experimental Analysis of Noise and Chatter Detection in Milling Depending on the Cutting Parameters

Abstract

© 2021, Springer Nature Switzerland AG. The aim of this paper was to experimentally analyse the generated noise and detect the appearance of self-excited vibrations, i.e. chatter vibrations during milling. There were performed three different types of experiments, based on the plan proposed in ([1]). In the first experiment, we measured sound pressure level—SPL [dBA] in dependence of cutting parameters, in second we measured SPL [dBA] induced by chatter vibrations and the stability lobes diagram is machined into workpiece while in the third experiment is also measured SPL [dBA] in dependence of radial depth of cut that increases linearly. Material of the workpiece was carbon steel and we used milling cutter with carbide inserts. Vertical machining centre was used for milling and noise was measured with microphone. Purpose of those experiments was to see how different cutting parameters influence on a generation of noise and vibrations. Also, in that way, we can select cutting parameters that will not lead us to unstable regions. The experimental results obtained can be used for future investigations in this field.
