“…Lee and Yang [62] accomplished a considerable enhancement of formability of an AZ31 magnesium alloy sheet in terms of the angle representing the forming limit during incremental forming by using a near-infrared heater. Throughout the experimental study on various tool lubricants and materials, Singh et al [63] showed that molybdenum disulphide and tool steel (EN-31) a mixture were appropriate for hot incremental forming of aluminium alloy sheets.…”

Traditional manufacturing operations require a long time and capital for prototype development and small batch production. Forming processes necessitate component specific and expensive dies since their preparation and design are time-consuming. In latest years, incremental sheet metal forming has acquired good attraction owing to its ability for small-batch productions and prototyping with generic tooling and short lead time. In this paper, a review of literature works has been presented describing investigations carried out on the formability of lightweight alloys, mainly Al alloys, Ti alloys and Mg alloys, during single point incremental forming (SPIF) process, considering the deformation mechanism, formability assessment techniques, forming limit curves, effects of influencing factors, and the effect of heating.

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.

“…various parameters like tool radius, vSD, lubrication, rotational tool speed, feed rate and material thickness affects the formability and dimensional accuracy of the product [5][6][7][8][9][10]. Singh et al [11] also justifies that the tool and lubrication have more influence in producing a sheet metal with better outputs. Kilani et al [12] tried to improve the outputs of iSF process using a new rolling ball tool.…”

Incremental Sheet metal Forming (ISF) Process is a suitable process which helps to produce various parts used in automotive sector by rapid prototyping. This method of producing a prototype helps industry in reducing the production cost. In ISF process, a final product is evolved through local deformation of the sheet metal made by the tool. Usually better formability is obtained when the tool makes a better contact with the sheet metal throughout the process. Improved formability elevates dimensional accuracy of the product, thus increases the market value of the product. A new tool with multiple ball ends capable of making multiple mating points over sheet metal was used in this research to enhance the efficiency of formability and surface finish. Ability of the new Multi-Point Incremental Forming Tool (MPIF) was investigated and compared to the existing Single Point Forming Tool (SPIF) based on the formability and surface finish. Forming Limit Diagram (FLD), Strain Distribution (SD) and Scanning Electron Microscope (SEM) were used to examine the formability of the sheet metal. The SEM & 3D-Surface roughness profilometer were used to observe the sheet metals surface finish. In addition to these experimental techniques a simulation results were also used to predict the stress and strain rate during forming process. The experimentation and simulation outcome shows that the MPIF provides superior formability and surface finish.
