Formability of Aluminum Alloys During Single Point Incremental Forming

Abstract

Single point incremental sheet metal forming has passed through a period of ample improvement with developing responsiveness from research societies and industries globally. The process has expressively spared the practice of using costly dies, which makes it an appropriate process for manufacturing prototypes and small batch production. It also discovers easiness in fabricating components of timeworn equipment. Additionally, in recent years, aluminum alloys become the most commonly used materials in the automotive, aeronautics, and transportation industries for their structural and other applications. The effect of various process parameters on the formability of Single Point Incremental Forming of aluminum alloys has been critically surveyed. Ultimately, this article also debated the dares associated with the Single Point Incremental Forming process and recommended some correlated research regions which probably charm significant research considerations in the future.

Improved geometric accuracy in single-point incremental forming of aerospace superalloy 625 using Taguchi desirability function analysis

“…Dabwan et al (2020) also said smaller step size (SS) was favorable for higher accuracy. Bishnoi and Chandna (2022a) concluded that smaller vertical SS and higher tool rotation speeds (TRSs) are favorable conditions for forming superalloy 625 components with higher geometric accuracy. Radu and Cristea (2013) demonstrated that during SPIF of products, a greater feed rate reduces part accuracy and higher tool rpm stimulates part accuracy.…”

“…To form the product, the sheet blank is fixed at an exact height in a specially designed fixture, and the CNC tool is moved in a predefined toolpath. The SPIF technique was first used to create metallic components (Pandivelan and Jeevanantham, 2015; Bishnoi and Chandna, 2022b), but researchers later used it to create shape-memory materials, sandwich and laminated sheets, composites, polymers and superalloys parts (Jackson, Allwood and Landert, 2008; Mohammadi et al , 2015; Centeno et al , 2017; Liu and Li, 2019; Wu et al , 2019; Bishnoi and Chandna, 2022a). Because the SPIF method is not affected by the work material’s chemical, electrical or thermal properties, it may be used in the transportation, solar, aerospace, medical, automotive and architectural sectors (Duflou et al , 2008; Trzepieciński et al , 2018; Bishnoi and Chandna, 2022b).…”

“…An emerging forming method known as the single-point incremental forming (SPIF) process has several advantages over classic sheet metal forming practices that can be implemented to address these issues. SPIF is especially beneficial in rapidly prototyping and manufacturing custom-made products for the aerospace, automotive, architectural and biomedical sectors (Trzepieciński et al , 2018; Bishnoi and Chandna, 2022). In the SPIF process, the smaller region of the workpiece is uninterruptedly deformed by the tool in a three-axis computer numerical controlled (CNC) machine till it procures the final shape according to the preset toolpath.…”
