In the cutting process, machine-tools vibrations are generally a real problem when the amplitude crosses the limits of dimensional or surface quality workpiece precision required. It is necessary to develop models taking into account the three-dimensional vibratory approach to control the vibrations phenomena. An experimental study has been realized to understand the behavior of the cutting system and to identify its vibrations properties. The displacement's localization of the tool in a spatial plan, showed by the experimental results, allows us to simplify the three-dimensional dynamical model. In this study, the experimental approach is completely presented and the first points of the three dimensional vibratory model are proposed according to the experimental results.
