Based on the mechanism of single-excitation elliptical vibration by means of opening chutes on the horn, a novel two-dimensional ultrasonic cutting system was developed. Vibration characteristics of the two-dimensional ultrasound cutting system were researched and the longitudinal and bending amplitude of the system with different number of chutes were obtained. By using developed two-dimensional ultrasonic vibration cutting systems, series of cutting experiments were carried out and cutting force characteristics were researched compared with that in traditional cutting.

Ultrasonic Vibration Cutting

Longitudinal-bending complex vibration can be realized by opening chute on the amplitude amplifier pole. Different longitudinal and bending amplitudes can be obtained under different angles and the number of the chutes. Based on the theory of two-dimensional ultrasonic cutting, the effects of the two dimensional amplitude on the cutting characteristics were analyzed experimentally in the paper. Research results show that the amplitudes of longitudinal and bending vibration have a great effect on cutting force and machining quality in two-dimensional ultrasonic vibration cutting of hard and brittle materials. When keeping constant longitudinal amplitude and increasing bending amplitude in a certain extent, the cutting force could be reduced and the machining quality of workpiece could be improved effectively. The research provides relevant basis for designing two-dimensional longitudinal bending vibration cutting system.

Orthogonal Tests

Ultrasonic vibration cutting experiments have been carried out for the machining of the plasma-sprayed Al2O3 coatings. The optimized value of V/Vc for the vibration cutting was obtained by a series of tests. The comparing experiments of the ultrasonic vibration cutting and the traditional cutting for the machining of the plasma-sprayed Al2O3 coatings by the cube nitride boride (CBN) and YC09 (hard alloy) lathe tools have been executed. The results indicate that the valid cutting time for the vibration cutting is 3-4 times longer than that for the traditional cutting, at the same time, the surface roughness values of the coatings machined by the vibration cutting are less than that machined by the traditional cutting. CBN and YC09 have been optimized as the candidates to machine the Al2O3 coatings through a series of vibration cutting tests carried out on the lathe tools of CBN and three hard alloys of YC09, YH3 and YGHT. The cutting parameters, such as V, aP and f, for the vibration cutting of the Al2O3 coatings by CBN and YC09 were obtained through the orthogonal tests and regression analysis. The obtained parameters have been utilized to machine the plasma-sprayed Al2O3 coatings for validation, and the results indicate that the ultrasonic vibration cutting is a competitive method to machine the plasma-sprayed Al2O3 coatings.
