“…Ultrasonic vibration-assisted grinding (UVAG) technique as an excellent method has been earned increasing attention to signi cantly improve the grindability of di cult-to-cut materials domestic and overseas [8,9]. Cao et al [10] performed the comparative study using CG and UVAG processes on nickelbased superalloy, and revealed that the tangential and normal grinding forces decreased by 30% and 40%, respectively, due to the acoustic softening and ultrasonic friction reduction effects. Dai et al [11] reported that the peening effect of abrasive ultrasonic vibration would raise brittle fracture and soften the workpiece surface during grinding SiC ceramic material, resulting in the signi cant reduction of normal force, tangential force and radial force by 69%, 52% and 71%, respectively.…”

Ultrasonic vibration assisted grinding (UVAG) combined with the ultrasonic vibrating method and CG process was proposed, aiming at improving the grindability of hardened steel in conventional grinding (CG) process. Comparative investigations on grinding force, temperature, and specific grinding energy for both grinding processes were studied in detail. In addition, the morphologies of wheel wear surface and ground surface were also conducted. Findings show that in comparison of CG processes, the grinding forces in UVAG are reduced greatly by 16.44% and 17.44%, for normal and tangential forces, respectively. The UVAG process attributes to a lower specific grinding energy by 8.30% owing to the increase of maximum undeformed chip thickness, and a smaller grinding temperature by 19.01% due to the improvement of coolant heat transfer capacity in the grinding arc zone. Meanwhile, the promising grain sharpness of wheels can be guaranteed, resulting from the enhanced cooling function on grinding arc zone and grains micro-fracture caused by ultrasonic impacting actions.

Composite manufacturing with multiple energy elds is an important source of processing technology innovation. In this work, comparative experiments on the conventional grinding (CG) and ultrasonic vibration-assisted grinding (UVAG) of hardened GCr15 steel were conducted with WA wheel. The grinding wheel wear patterns and chips were characterized. In addition, grinding force, force ratio, and ground surface quality were investigated to evaluate wheel performance. Results illustrate that the interaction between abrasive grains and workpiece in UVAG process has the characteristics of high frequency and discontinuity. The wear property of abrasive grains is changed and the grinding force is decreased because the generation of micro-fracture in abrasive grains improves the grinding wheel self-sharpening.Better surface quality is obtained, the surface roughness is reduced by up to 18.96%, and the number of defects on the machined surface is reduced through the superior reciprocating ironing of UVAG.Accordingly, WA wheel performance is improved by UVAG.

Tangential ultrasonic vibration-assisted grinding (TUAG) has a wide prospect in machining difficult-to-machine materials. However, the surface generation mechanism in TUAG is not fully recovered. This study proposes an analytical model of the surface topography produced by TUAG. Based on the model, the surface topography and roughness are predicted and experimentally verified. In addition, the influence of the grinding parameters on the surface topography is analyzed. The predicted surface topography well coincides with experimental measurements, and the prediction error in surface roughness Ra by the proposed model is less than 5%. Compared with conventional grinding, TUAG produces a surface with more uniform scratches and surface roughness Ra was reduced by up to 27% with the proper parameters. However, the improvement of surface roughness in TUAG is weakened when grinding speed or depth of cut increases. Moreover, the influence of the ultrasonic vibration amplitude on the surface roughness is not monotonous. With the grinding parameters selected in this study, TUAG with an ultrasonic amplitude of 7.5 μm produces the minimum surface roughness.
