Abstract
A vibration assisted machining (VAM) system, including: a frame; a vibration element mechanically coupled to the frame; a cutting tool holder connected to the vibration element; and a workpiece holder coupled to the frame. The vibration element includes a first piezoelectric (PZT) actuator and a second PZT actuator, which are adapted to generate a substantially elliptical tool path in a vibration plane of the VAM system. The VAM system also includes a third PZT actuator coupled between the frame and either the vibration element or the workpiece holder. This third PZT actuator is coupled to the frame such that its polarization axis is substantially in the vibration plane and substantially perpendicular to the feed direction of the VAM system.
