Abstract
Vibrations appearance, either unstability system, is the result of the dynamic interaction of the cutting process with the elastic system of machine tools in various working conditions. Our objective is to develop an experimental three-dimensional dynamic model in milling. Our purpose is to applied this model to optimize the cutting parameters and to monitor cutting process, milling tool and machine-tool. To reach the detailed knowledge of the dynamic phenomena we divide our study into two parts : the machine and the cutting process. The dynamic analysis of the machine is compulsory before modelling the vibratory phenomena during the cutting. A dynamic analysis method is developed to characterize completely the various machine tools components.
