The quest for higher machine accuracy demands high dynamic rigidity, which requires a good understanding and control of vibration in machining. Such vibration is complex and can be excited by either cutting or feeding.

This paper reports an investigation involving the identification of the possible source and mode of a lower natural frequency (35 Hz) of the Y-axis ball-screw drive of a Beaver VC35 Milling Machine by analytical and finite element methods [1]. It contributes not only to the knowledge of how the ball-screw vibrates laterally, but also, conceptually, to the need for its inclusion in the interaction between the control and the mechanical structure. It also demonstrates the application of FE vibrational analysis to machine tools.
