1. A vibration assisted machining (VAM) system, comprising:

  • a frame;

    a vibration element mechanically coupled to the frame, the vibration element including a first piezoelectric (PZT) actuator and a second PZT actuator adapted to generate a substantially elliptical tool path in a vibration plane of the VAM system;

    a cutting tool holder connected to the vibration element;

    a workpiece holder coupled to the frame; and

    a third PZT actuator coupled between the frame and one of;

    the vibration element;

    orthe workpiece holder;

    wherein the third PZT actuator is coupled to the frame such that a polarization axis of the third PZT actuator is substantially in the vibration plane and substantially perpendicular to a feed direction of the VAM system.
