“…Tang et al [21] analyzed the instantaneous contact interface state under ultrasonic vibration, and elaborated the friction reduction mechanism of UVAG. Similarly, the UVAG process improves the heat transfer ability of coolant and the self-sharpening ability of abrasives, resulting in a lower grinding force and temperature, as described in other literatures [22][23][24][25]. Moreover, UVAG has proved to be an efficient technique for machining brittle materials [26][27][28][29].…”

“…In recent years, ultrasonic vibration-assisted grinding (UVAG) technology has been widely concerned, aiming at obtaining high surface integrity, especially for difficult-to-cut materials in aerospace industries [16]. Those researches show that the usage of ultrasonic composite technology contributes to the reduction of the grinding forces and temperature, the significantly improvement of grinding quality, and an enhancement in material removal rate during machining difficult-to-cut materials [17][18][19][20][21][22][23][24][25]. Ding et al [17] developed a radial ultrasonic vibration-assisted machining device and applied it to machining the particle-reinforcing titanium matrix composites.…”

Gamma titanium-aluminum intermetallic compounds (γ-TiAl) have an important application significance in the field of aero-engines owing to their excellent mechanical properties (e.g., high-temperature resistance, high toughness, etc). Grinding as an important method was used to realize the high efficiency and precise machining for difficult-to-cut materials. However, the machining defects (e.g., adhesion, cracks, and even burns, etc) were confronted on machined surface of γ-TiAl materials under high grinding force and temperature loads. In this case, the new machining methods combined with the ultrasonic vibration and high-efficiency deep grinding technology was proposed to improve the machining quality and efficiency. Comparative trials of ultrasonic vibration-assisted high efficiency deep grinding (UVHEDG) and high efficiency deep grinding (HEDG) were carried out to study the grinding performance, in terms of the grinding force, grinding temperature, specific grinding energy, and machining surface quality. Results show that UVHEDG possess the lower grinding force and temperature by 38.69% and 39.05% compared with HEDG, respectively. In addition, the employment of ultrasonic vibrations contributes to maintain the abrasive sharpness, and thus the specific grinding energy is reduced by 23.95%. Ground surface roughness can be reduced by 19.53%, and the grinding surface quality is effectively improved due to the lubrication effect and track overlap effect under ultrasonic vibration.
