A Miniature Cutting Tool for Elliptical Vibration-Assisted Turning: Design and Kinematical Analysis

Article Preview

Abstract:

Vibration-assisted turning combines conventional turning with high-frequency, small-amplitude tool vibration to improve the machining quality of intractable materials like titanium and nickel alloys used in aerospace applications. Elliptical vibration-assisted turning is a kind of two-dimension vibration-assisted turning. The tool tip is driven in an elliptical locus. This paper illustrates a miniature cutting tool designed for elliptical vibration-assisted turning and proposes a set of general formulas by kinematical analysis. These formulas show the effects of different vibration parameters on the final elliptical locus, and these effects are verified using MATLAB at the end of this paper.
