Abstract
This paper describes the design of the ultrasonic elliptic-vibration shoe and its performance in ultrasonic elliptic-vibration shoe centerless grinding. First, the vibration modes of the shoe for the bending and longitudinal directions are discussed and determined from the point of view of fixing the support of the shoe. Then the structure and dimensions of the shoe are determined by FEM analysis. In order to clarify the performance of the produced shoe, an evaluation apparatus is built. The elliptic motions under different applied voltages are investigated by using laser vibrometers. Finally, the workpiece rotational motion control tests are carried out. As a result, it is clear that the workpiece rotational speed changes linearly with variation of the applied voltage. This indicates that the workpiece rotational motion can be precisely controlled by the elliptic motion of the shoe.
