An experimental plan for noise analysis and chatter detection in milling depending on the cutting parameters

Abstract

Improving the performance of cutting operations has led to an increase in noise levels, especially when milling. Main source of noise in milling are self-excited vibrations, i.e. chatter vibrations. In the literature is usual to compare noise level according to the spindle speed, feed per tooth, axial depth of cut and radial depth of cut. Purpose of that comparisons is to gain insight in effect of cutting parameters on occurrence of noise and vibrations. Here are presented plan of experiments and variants of the sample forms for identification of noise generated by chatter vibrations, in dependence of mentioned cutting parameters. That experiments we can use to get conclusions about cutting parameters that causes instability of process trough vibrations and reduce productivity. Based on results obtained it is possible to select cutting parameters which enable us to improve productivity and part quality by avoding unstable regions.
