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.

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.

This paper presents a basic principle of ultrasonic vibration metallographic sample cutting machine. Ultrasonic vibration cutting machine contains four parts: the ultrasonic generator, the transducer,the horn and the tools. The cutting machine uses ultrasonic fregnency as the tool of small amplitude vibration.It is a special processing because the surface of the work piece material is gradually broken by the beating of the ultrasonic frenquency and the abrasice which wonders in the liquid that is among the workpieces. The results indicates that the method can effectively improve the quality of surface and precision of the processing surfaces of workpieces.

Precision ultrasonic vibration cutting is a promising technology in field of precision and ultra-precision machining. It is a kind of the pulsing cutting process with a constant vibration frequency and sine-wave amplitude of vibration. In this article, a rational model of cutting force in vibration cutting is established, and the vibration cutting mechanism is analyzed. Specially, by the method of numerical simulation, the effect regulation of amplitude of vibration on cutting force is theoretically discussed for the first time in precision vibration cutting. And the relationship between cutting parameters and cutting force is probed into on the different cutting conditions.
