Abstract:

Carbon fiber composites have been widely used in various extreme service environments and the proportion and importance have increased due to their excellent properties such as lightweight, high temperature and corrosion resistance. Due to size and assembly requirements, subsequent machining of composites is required. Rotary ultrasonic machining technology has significant advantages in improving the removal efficiency of carbon fiber composites, reducing cutting force and improving machining quality, making it a research hotspot in field of difficult-to-machine materials manufacturing. In recent years, domestic and foreign scholars have carried out considerable research work and achieved fruitful results in rotary ultrasonic drilling, milling and grinding. However, there are significant differences in the influence mechanism of various ultrasonic vibration forms intake on the cutting effect of carbon fiber composites under different machining methods and the coupling process with the cutting energy field. Moreover, there is still considerable room for improvement in both the depth and breadth of research on the surface integrity and service performance of various carbon fiber composites. Therefore, this paper summarizes and condenses the domestic and foreign literatures on material removal mechanism, machining characteristic, surface quality research and practical engineering application, and predicts the development trend of rotary ultrasonic machining of carbon fiber composites.

Key words: rotary ultrasonic machining, carbon fiber composites, fiber fracture, surface damage suppression, surface roughness
