Ultrasonic Vibration Cutting

With the use of ultrasonic-assisted diamond cutting, an optical surface finish can be achieved on hardened steel or even brittle materials such as glass and infrared materials. The proposed ultrasonic vibration cutting system includes an ultrasonic generator, horn, transducer, cutting tool and the fixture. This study is focused on the design of the ultrasonic vibration cutting system with a high vibration frequency and an optimized amplitude for hard and brittle materials, particularly for moulded steel. A two-dimensional vibration design is developed by means of the finite element analysis (FEA) model. A prototype of the system is manufactured for the test bench. An elliptical trajectory is created from this vibration system with amplitudes of micrometers in two directions. The optimization strategy is presented for the application development.

Force Characteristics

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 Cutting

The ultrasonic transmission model is established in the ultrasonic cutting process based on the ultrasound oval cutting device made by ourselves and the different vibration cutting effects is analyzed under the ultrasonic cutting process in this paper. The ultrasonic transmission at the contact interface is vulnerably affected by preload force factors and so on by the vibration experiments of the ultrasonic vibration cutting system.

Ultrasonic Vibration Cutting

Ultrasonic vibration cutting can be widely used in lathe, planer, milling machine, grinding machine, thread processing and gear processing, etc. Ultrasonic vibration cutting system is composed mainly of ultrasonic generator, ultrasonic transducer, luffing rod, cutting tool, etc. Here, ultrasonic generator is the most important. The stand or fall of signal, which is produced by ultrasonic generator, has direct influence on anticipated effect and ability of ultrasonic machining. In order to generate a signal, which can be suitable for ultrasonic machining, ultrasonic vibration cutting system is studied, and ultrasonic signal generator based on direct digital frequency synthesis (DDS) is designed and conducted a cutting test with this ultrasonic machining system. The results show that the signal generator, which is made up by DDS technology, can generate the signal with stability, reliability and greater flexibility, and can be fully applicable to the ultrasonic machining.
