“…Meanwhile, the grinding forces are always kept at a low level under UVHEDG process. As stated in our previous study [20], the intermittent grinding behavior in UVHEDG increases the impact depth and improves cutting thickness of a single abrasive particle during removing materials. Thus, the proportion of sliding and ploughing process is reduced, and more energy is used in chip forming stage.…”

“…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.

Many problems of GCr15SiMn high-carbon chromium bearing steel have been found in the ordinary grinding (OG) process. Aiming at the problems of high grinding force, low residual compressive stress and low surface quality, ultrasonic machining technology is combined with OG. The test of ultrasonic vibration assisted grinding (UVAG) GCr15SiMn high carbon chromium bearing steel is carried out. The residual stress, surface roughness, grinding force, and surface morphology are analyzed by changing machining parameters. The research showed that as the grinding depth and feed speed become larger, the grinding force increased, when the spindle speed rises, the grinding force becomes smaller. In the test range, with the ultrasonic amplitude from small to large, the grinding force from large to small. The ultrasonic grinding force is 27.8% lower than that of OG. The surface roughness increases with increasing grinding depth and feed speed and decreases with increasing spindle speed and ultrasonic amplitude, and at an amplitude of 6 μm, the surface roughness is reduced by 27% compared to OG. When the feed speed and grinding depth are lowered or the ultrasonic amplitude is increased, the surface residual compressive stress is increased. Compared to OG, it is increased by more than 13.5% under the same parameters. At the same time, the phenomenon of burrs and surface tears can be reduced, and the surface quality of the workpiece becomes better.

“…By using the optimal process parameters based on FEM of vibration characteristics, sufficient tests on the ultrasonic vibration-assisted processes indicated a superior surface finish 15 and improved grinding burn and thermal damage. Moreover, Cao et al 16 created an innovative hybrid processing technique called ultrasonic vibrationassisted grinding (UVAG), which may effectively reduce the amount of force used during grinding, reduce the temperature during grinding, and improve surface integrity. The production technologies for the evaluation of surface quality in the context of precision machining operations are also summarized in Zhao et al 17 Sihag et al 18 used ultrasonic assistance in the singledisc MAF process to polish the copper alloy.…”

To polish the surface of silicon wafers, the impact of ultrasonic vibration assistance on the double disc chemo-magnetorheological finishing was investigated. The in-house setup was fabricated to provide vibrations to the workpiece during the polishing in the longitudinal direction. The central composite design (CCD) approach was adopted in experiment planning to understand the influence of process parameters (like magnets rotation, abrasive concentration, and ultrasonic power) on the surface roughness ([Formula: see text]). A 3D optical profilometer was employed to check the surface roughness of the polished wafers. The individual and interaction of significant process factors affecting were determined using the analysis of variance (ANOVA) technique. A regression equation based on response surface methodology was developed. The process parameters were optimized using a genetic algorithm to maximize the change in surface roughness before and after polishing. The experiment performed at an optimized set resulted in an average surface finish of 3.4 nm. A 3D surface plots and scanning electron microscopy (SEM) were used to understand the changes on the surfaces of unpolished and polished samples at the optimized parameters.
