“…This region of failure was also characterized by higher hardness (158±9 HV) than that of the hardness near the base. Zhai et al 174 in in their study found favourable effect of ultrasonic vibrations on surface roughness. With ultrasonic vibration-assisted ISF process, sharp ridges was found to be flattened due to reciprocating motion of the tool when step-depth was kept lower than 0.1 mm, however, in the case of conventional ISF process sharp peaks were observed.…”

“…Products of the vibratory forming tool manufactured by Amini et al [73] proved to have positive and significant effects on the process of incremental forming of AA1050 sheets where the ultrasonic vibrations had been axially added to the forming tool to investigate the effect of longitudinal vibrations. Zhai et al [74] asserted that adding ultrasonic vibration led to a reduction in the forming force, and an early forming step can be produced in the incremental sheet-forming process of AA-1050-O material.…”

Lightweight materials, such as titanium alloys, magnesium alloys, and aluminium alloys, are characterised by unusual combinations of high strength, corrosion resistance, and low weight. However, some of the grades of these alloys exhibit poor formability at room temperature, which limits their application in sheet metal-forming processes. Lightweight materials are used extensively in the automobile and aerospace industries, leading to increasing demands for advanced forming technologies. This article presents a brief overview of state-of-the-art methods of incremental sheet forming (ISF) for lightweight materials with a special emphasis on the research published in 2015–2021. First, a review of the incremental forming method is provided. Next, the effect of the process conditions (i.e., forming tool, forming path, forming parameters) on the surface finish of drawpieces, geometric accuracy, and process formability of the sheet metals in conventional ISF and thermally-assisted ISF variants are considered. Special attention is given to a review of the effects of contact conditions between the tool and sheet metal on material deformation. The previous publications related to emerging incremental forming technologies, i.e., laser-assisted ISF, water jet ISF, electrically-assisted ISF and ultrasonic-assisted ISF, are also reviewed. The paper seeks to guide and inspire researchers by identifying the current development trends of the valuable contributions made in the field of SPIF of lightweight metallic materials.

“…It was shown that the ultrasonic vibration could improve both the viscosity and velocity field in the complex-shape micro-cavity, and thus further improve the filling capacity and uniformity of polymer melt. Zhai et al 27 used ultrasonic-vibration machining in the forming process of the incremental sheet. It showed that the parts' surface quality could be significantly improved.…”

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.
