SELF – EXCITED VIBRATION AND NOISE IN MACHINE TOOLS

Abstract

The aim of present paper to show the linear relation between noise and vibration amplitudes with different phase time shift in oblique – cutting. The level of stability is increased as the depth of cut to is decreased because the ratio (to / so) reduces the values of the dynamic chip thickness coefficients in oblique – cutting. The diagnosis and reductions of the vibration and noise in oblique- cutting were made to show firstly the effect of rotational speed and depth of cut changes on the calculated stability chart, secondly the calculated stability chart of vibration which is based on the complicated theory can
