“…This section uses a single factor analysis method to turn 304 stainless steel using common turning (CT) and ultrasonic vibration-assisted turning (1D-UVT, EUVC, 3D-USVT) to obtain different parameters (v, a p , and f) the surface roughness and its changing law. To better analyze the influence of different processing methods on surface roughness, 1D-UVT [12], UEVT [43], and 3D-USVT all adopt the best vibration parameters corresponding to each processing method.

“…𝜏𝐴 𝑐 𝑠𝑖𝑛𝜑𝑐𝑜𝑠(𝜑 + 𝛽 − 𝛼) = 𝜏𝑏 𝐷 ℎ 𝐷 𝑠𝑖𝑛𝜑𝑐𝑜𝑠(𝜑 + 𝛽 − 𝛼) (12) where τ represents the shear stress, A c represents the cutting area, b D represents the cutting width, and h D represents the cutting thickness. According to equation (12), it can be concluded that when other cutting conditions remain unchanged and the a p is increased, the cutting area will increase accordingly, resulting in greater deformation resistance and friction, higher cutting force, which will eventually lead to vibrations in the entire turning system, the surface roughness becomes larger.

“…14(c) shows that with the increase of the f, the Sa under the four different cutting methods shows an upward trend, but the Sa change rate is slightly different. According to equations ( 4) and (12), it can be seen that when the feed amount is small, the residual geometric height and cutting force generated when cutting the workpiece are small. The cutting vibration is not obvious, and the Sa is small.…”

“…The results show that the surface quality obtained by the 1D-UVT was improved by 75%-85% compared to CT under the same cutting conditions. Xu et al [11][12] analyzed the machining performance of 1D-UVT and CT by machining AISI304 and Inconel718 and discussed the changing trend of surface roughness under different cutting parameters. The experimental results show that the surface roughness after ultrasonic vibration is significantly reduced in all cases.…”

To improve the machining performance of different processing materials, a three-excitation ultrasonic spatial vibration-assisted turning system is proposed, which realizes the non-unity of the plane where the cutting trajectory of the tool is located. The influence and formation law of three-excitation ultrasonic spatial vibration-assisted turning on the surface roughness of the workpiece under different vibration parameters (amplitude) and machining parameters (cutting speed, cutting depth, and feed) were analyzed by response surface methodology. The results show that in terms of vibration parameters, the influence of ultrasonic vibration applied in the horizontal direction on surface roughness is significantly greater than that of ultrasonic vibration applied in the vertical direction, while the feed has the greatest influence on surface roughness, followed by cutting speed. The surface roughness of common turning, one-dimensional ultrasonic vibration-assisted turning, ultrasonic elliptical vibration-assisted turning, and three-excitation ultrasonic spatial vibration-assisted turning were theoretically analyzed and experimentally compared. The results show that compared with the other three turning methods, the three-excitation ultrasonic spatial vibration-assisted turning can obtain a lower surface roughness and have good machinability.

“…The manufacturing equipments for UAT have been exploited in the both domestic and overseas, whereas, there exist shortcomings of expensive factory cost, incapacious existing applications and low-grade commonality in this manufacturing equipment, as a consequence, it is difficult to popularize [15,16]. In view of the above reasons, the UV system is fixed on the generic turning-lathe in this investigation to satisfy the claim of the UAT in down-to-earth production.…”

The 5A06 Al-Mg alloy is a soft material, and the phenomenon of knife sticking is extremely serious during cutting, likewise, it is easy to generate build-up edges. Therefore, it is difficult to acquire good surface quality in turning. For this purpose, the ultrasonic theory and cutting theory are fully combined in this study, and the machining mechanism of conventional turning (CT) is changed by applying ultrasonic vibration (UV) to the cutting tool, so as to build up the machining results. The turning experiments of 5A06 Al-Mg alloy with or without UV are carried out under different process parameters, and through which the effects of ultrasonic amplitude (UA), feed rate (FR), cutting depth (CD) and cutting speed (CS) on the surface roughness of machined workpiece are investigated and analyzed. The consequences show that the process parameters have a different degree of effect on surface roughness. And there are special process parameters suitable for UV assisted turning (UAT), under which the processing results of UAT is obviously better than that of CT. In addition, it is found that by contrast experiment of surface topography under ideal process parameters built-up edges, surface scratches and other phenomena are not easy to arise in UAT to obtain the better surface topography than CT.

Material extrusion (ME) technique has been one of the most popular additive manufacturing techniques because of its environmental friendliness, low cost, simple operation, and so forth. However, significant surface defects occur on ME parts due to the discontinuity between adjacent layers. For this reason, a new method, using ultrasonic‐vibration machining, was innovatively proposed to improve the ME parts' surface quality. A theoretical surface roughness (SR) model of the ME parts processed by using ultrasonic vibration was established. An ultrasonic‐vibrating ME equipment was then set up by refitting an ordinary one and the samples built without and with ultrasonic‐vibration machining utilized were prepared, respectively. With the laser microscope, the built parts' SR was tested and determined. Compared the predicted SR results with the measured ones, the theoretical model was verified. The influence of different ultrasonic vibration on the surface quality of ME parts was also discussed, clarifying the corresponding mechanism.
