doi:10.3901/JME.2017.19.128

Abstract

Abstract: As a rapidly developing processing technology, ultrasonic cutting technology is more and more widely used in the processing of composite materials, especially the low-rigidity composite materials represented by paper honeycomb material. Experiments are conducted to study the ultrasonic cutting of aluminum honeycomb. Through the analysis of the cutting force under different amplitudes and different feed speeds, and the macroscopic and microscopic topographies of the honeycomb workpieces after ultrasonic cutting, the feasibility and advantages of ultrasonic cutting of aluminum honeycomb are verified. The experimental results show that there is no obvious damages and no burrs on the macroscopic structures of honeycombs by ultrasonic cutting, and the microscopic surface topography can be improved by increasing the ultrasonic amplitude and the feed speed. The ultrasonic vibration of cutting tool can significantly reduce the cutting force, and with the increase of ultrasonic amplitude at the same feed speed, the cutting force becomes smaller. With the increase of the feed speed under the same ultrasonic amplitude, the cutting force becomes larger, but the change is small. Through the force analysis of ultrasonic cutting of aluminum honeycomb, the influences of ultrasonic amplitude and feed speed on cutting force are discussed and compared with experimental results. The internal reasons of ultrasonic cutting force variations are analyzed theoretically.
