“…When the speed reaches 600 𝑟 𝑚𝑖𝑛 ⁄ , the surface roughness reaches the minimum value. According to the analysis of equation (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), this was because the cutting speed increases with the increase of spindle speed. When the cutting speed exceeds the critical cutting speed, SR>1, the ultrasonic separation phenomenon will be weakened, and the effect of ultrasonic turning will also be weakened.…”

In order to obtain 7075 aluminum alloy deep hole tube parts with better surface quality, the two-dimensional ultrasonic elliptical vibration turning (2D-UEVT) was studied. The tool tip trajectory model and the surface roughness model of 2D-UEVT deep hole were established. It was found that 2D-UEVT could obtain lower surface roughness than common turning (CT) through analyzing the theoretical model. Finally, the effects of turning parameters and acoustic parameters on surface morphology were studied by four-factor four-level orthogonal test. The experimental results indicated that the surface roughness Ra value decreased in different degrees after the 2D-UEVT. However, various turning parameters and acoustic parameters had different effects on the reduction of Ra. With the increase of the feed rate and spindle speed, the surface roughness Ra shows a trend of decreasing first and then increasing. With the increase of ultrasonic amplitude, the Ra displayed increasing first and then decreasing. The influence of cutting depth on the roughness is not significant. The results demonstrated that better surface texture and surface quality can be obtained with lower feed rate, medium ultrasonic amplitude and spindle speed.

The study focused on the use of two-dimensional ultrasonic elliptical vibration boring (2D-UEVB) to improve the surface quality of deep hole tube parts made from 7075 aluminum alloy. The tool tip trajectory model and the surface roughness model of 2D-UEVB deep hole were established. It was found that 2D-UEVB could obtain lower surface roughness than common boring (CB) through analyzing the theoretical model. Finally, the effects of boring parameters and acoustic parameters on surface morphology were studied throughsingle factor test and four-factor four-level orthogonal test. After the 2D-UEVB, the surface roughness Ra value decreased in different degreesaccording to the experimental results. However, the reduction of Ra was affected differently by the various acoustic parameters and boring parameters. With the increase of feed rate, the surface roughness Ra shows a significant increasing trend. With the increase of spindle speed, the surface roughness Ra shows a trend of decreasing first and then increasing. The Ra displayed a continuous decreasing trend with the ultrasonic amplitude increased. The influence of cutting depth on the roughness is not significant. The results demonstrated that better surface texture and surface quality can be obtained with lower feed rate, medium spindle speed and larger ultrasonic amplitude in two-dimensional ultrasonic vibration boring.

“…The overlapping effect of two adjacent elliptical tracks in the feed direction reduces the height difference of the surface and improves the surface quality. Under the same cutting parameters, the appropriate ultrasonic amplitude has a positive effect on the surface micromorphology [18]. Tan R [19] used UEVC to process Ti-6Al-4V alloy microgrooves.…”

Aluminum (Al)-based silicon carbide (SiC) material composites are considered as difficult-to-machine materials because of the presence of hard reinforced SiC particles, which results in a greater cutting force and poor surface integrity during the machining process. This paper uses two finite element models to study the difference in the machining mechanism between ultrasonic elliptical vibration cutting (UEVC) and ordinary cutting (OC). Moreover, this paper mainly focuses on the influence of UEVC on cutting force, von Mises stress distribution, surface integrity, and chip formation. The models are validated by comparing chip shapes and machined surface features in OC machining Al/SiCp experience from the literature. Simulation results indicate that the cutting mechanism of Al/SiCp on UEVC is different from that of OC and has several good properties. At the same cutting parameters, high frequency vibration makes the cutting force of UEVC exhibit variable periodicity and reduces average cutting force. The instantaneous impact of tool and fast separation results in a more concentrated von Mises stress distribution, thereby resulting in the particles having a greater break degree than that obtained with OC. A comparison of the surface roughness values from the simulation result shows that UEVC obtains better surface integrity than OC does.
