Abstract

The invention discloses a two-dimensional ultrasonic elliptical vibration machine tool and a part machining control method thereof. An ultrasonic tool system is mounted on a slide carriage of a vertical guide rail, two ultrasonic vibrators are perpendicular in spatial position and are connected with the vertical guide rail through a T-shaped fixing plate and an L-shaped fixing plate respectively, and a cutter is mounted on the vertical ultrasonic vibrators and is fixed and locked through set screws. The two ultrasonic vibrators of the tool system are perpendicular to each other, the finally output motion trail of the cutter is an ellipse, and the elliptical trail can be controlled by controlling cutter parameters such as the rake angle, the clearance angle, the rake face length, the flank face length and the blunt circle radius of the cutter and vibration parameters such as the transverse amplitude, the longitudinal amplitude, the vibration frequency and the phase difference of the cutter; and the surface scallop height under different machining conditions is obtained through related calculation, so that the research on an ultrasonic elliptical cutting mechanism is facilitated, and a theoretical basis is provided for the selection of a blunt circle radius.
