Abstract : Self-excited or chatter vibrations are well known among milling machine builders and users. Nowadays, chatter is one of the most important restrictions of the milling process. Self-excited vibrations prevent obtaining the required accuracy in workpiece, reducing the lifetime of the cutter and the mechanical components of the machine. Due to chatter vibrations, the dynamic stiffness of the structure of the milling machine limits the productivity in steel and cast iron roughing. Hence the stability of this kind of process is an indirect way to measure the dynamic stiffness of the design. This paper presents different stability models and proposes the most suitable for the determination of the cutting performance of universal milling machines. Finally the cutting performance and the dynamic behaviour of the milling machine is determined combining the measurements of the dynamic stiffness of the structure, the stability models, cutting tests and modal analysis.
