Purpose This present research aims to identify the optimum process parameters for enhancing geometric accuracy in single-point incremental forming of aviation-grade superalloy 625. Design/methodology/approach The geometric accuracy has been measured in terms of half-cone-angle, concentricity, roundness and wall-straightness errors. The Taguchi Orthogonal-Array L9 with desirability-function-analysis has been used to achieve improved accuracy. Findings To achieve maximum geometric accuracy, the optimum setting having a tooltip diameter of 10 mm, a step-size of 0.2 mm and a tool rotation speed (TRS) of 900 RPM has been derived. With this setting, the half-cone-angle accuracy increases by 42.96%, the concentricity errors decrease by 47.36%, the roundness errors decline by 45.2% and the wall straightness errors reduce by 1.06%. Practical implications Superalloy 625 is a widespread nickel-based alloy, finding enormous applications in aerospace, marine and chemical industries. Originality/value It has been recommended to increase TRS, reduce step-size and use moderate size tooltip diameter to enhance geometric accuracy. Step-size has been found to be the governing parameter among all the parameters.

“…Very low stepdown values, as could be used to obtain a semi-polished surface finish, typically lead to cyclic loading of the sheet surface and, depending on the material being processed, can result in early failure due to fatigue phenomena. Numerous studies have been carried out that have attempted to quantify the influences and sensitivities of specific process parameters through means of an empirical and/or analytical Design Of Experiments (DOE), often accompanied by an ANalysis Of VAriance (ANOVA) (Leon et 2013, Desai et al 2014, Sarraji et al 2012, Bahloul et al 2014, Jeswiet, Hagan et al 2002. While the specific sensitivities appear to be dependent on the experimental setup, general trends have been noted and are consistent with what has already been stated.…”

Incremental sheet metal forming in general and Single Point Incremental Forming (SPIF) specifically have gone through a period of intensive development with growing attention from research institutes worldwide. The result of these efforts is significant progress in the understanding of the underlying forming mechanisms and opportunities as well as limitations associated with this category of flexible forming processes. Furthermore, creative process design efforts have enhanced the process capabilities and process planning methods. Also, simulation capabilities have evolved substantially. This review paper aims to provide an overview of the body of knowledge with respect to Single Point Incremental Forming. Without claiming to be exhaustive, each section aims for an up-to-date state-of-the-art review with corresponding conclusions on scientific progress and outlook on expected further developments.

“…For a given tool path strategy and wall angle, the quality of part produce from SPIF process depends upon above mentioned parameters. The researchers generally investigate the responses such as geometrical accuracy, surface finish [5] and thinning in the formed part. It has been observed that as the wall angle increases the thinning of the blank increases [2].…”

Single Point Incremental Forming (SPIF) process is one of the advanced forming techniques that industry has nowadays. Improved formability is one of the major advantages of the process. However, it is associated with limitation such as thinning of blank and poor geometrical accuracy of the formed part. In this study, forming behaviour of homogeneous blanks during the SPIF process has been investigated. A simulation study has been carried out using ABAQUS/Explicit. Effect of change in thickness, yield strength, strain index and strength coefficient of blank on responses like Plastic Equivalent Strain (PEEQ), percentage of thinning and geometrical accuracy of formed component has been evaluated. It has been found that change in the thickness has major effect on PEEQ and geometrical accuracy. Regarding percentage of thinning, change in the yield strength of blank is found to be majorly affecting.
