Abstract

The peripheral milling of thin walled structure generates vibrations of the workpiece, which affect the quality of the machined surface. A reduction of tool life and spindle life is also observed. The stability lobes theory allows us to determine cutting conditions for which the vibrations will not appear. These cutting conditions depend on dynamic properties of the workpiece. Machining is a working process by material removal, so, the dynamic properties will change during the machining. We show in this paper how to integrate in the stability lobes theory this variation of the dynamic properties. These computed results are compared with real experiments.
