VIBRATORY ANALYSIS OF A CUTTING TOOL

Abstract

The vibration problem of the cutting tools during machining has an important influence on the surface quality and the manufacturing tolerances. In this paper, we presented a modelling of the dynamic behaviour of a cutting tool, the goal is to determine, by the method without mesh of Galerkin, the frequencies and the clean modes of a tool starting from the kinetic energy and the deformation energy. A program, developed in MATLAB, makes it possible automatically to generate the calculation of the frequencies and the clean modes, under various boundary conditions.
