Abstract: The actions of cut applied to the elastic system generate relative tool/part displacements, which induce a temperature increasing in the components of the machine tools, its environment, the system-tools-part and generate vibrations. The experimental procedures used, at the dynamic level, made it possible to determine the elements necessary to analyze the influence of the geometry of the tool, its displacement and evolution of the contacts tool/part and tool/chip on surface carried out.
Key words: regenerative vibrations, chip variation, self-excited frequencies, experimental device, dephazing.
