Abstrakt: We have determined in which conditions we have a regenerative vibration cases (chatter). We have used the simulation of a machining system dynamic behaviour. A cutting force law was obtained by an indirect method, by comparing between simulation results and experimental ones. On propose de d?terminer dans quelles conditions apparaissent des vibrations auto-entretenues (broutement). Pour cela, on utilise la simulation du comportement dynamique d'un syst?me d'usinage et une loi de force de coupe est obtenue par une m?thode indirecte, en comparant les r?sultats de la simulation ? ceux issus de l'exp?rimentation.
