“…The surface profile formed by the EVA cutting is in good agreement with the designed one, but that finished without vibration is obviously shallower. Such kind of improvement was also observed in the UVA cutting of optical glass BK7 [110], SF6 [111], SF11 [112] and fused silica [3,51,113].…”

“…At the maximum chip thickness, flow happens when the maximum shear strain exceeds a critical level. In addition, the entry speed, maximum speed, contact time and distance during the tool-workpiece contact in a vibration cycle influence chip development [112,115]. A complete chip is easier to form when both the entry speed and maximum speed are low (thus stress level is low).…”

Ultrasonic vibration-assisted (UVA) machining is a process which makes use of a micro-scale high frequency vibration applied to a cutting tool to improve the material removal effectiveness. Its principle is to make the tool-workpiece interaction a microscopically non-monotonic process to facilitate chip separation and to reduce machining forces. It can also reduce the deformation zone in a workpiece under machining, thereby improving the surface integrity of a component machined. There are several types of UVA machining processes, differentiated by the directions of the vibrations introduced relative to the cutting direction. Applications of UVA machining to a wide range of workpiece materials have shown that the process can considerably improve machining performance. This paper aims to provide a comprehensive discussion and review about some key aspects of UVA machining such as cutting kinematics and dynamics, effect of workpiece materials and wear of cutting tools, involving a wide range of workpiece materials including metal alloys, ceramics, amorphous and composite materials. Some aspects for further investigation are also outlined at the end.
