Abstract
An elliptical vibratory cutting apparatus includes a control mechanism which applies a sinusoidal voltage having a predetermined phase difference to piezoelectric elements. Flexure vibrations are accordingly generated in X and Y directions. The vibrations in the X direction cause interference with the vibrations in the Y direction and vice versa. An amount of interference, caused by vibrations in one direction, with vibrations in another direction, is correctively eliminated by the control mechanism (interference eliminating unit. A workpiece is thus cut by means of a cutting tool through elliptical vibrations with high precision.
