Single point incremental forming (SPIF) is used to form small batch production of different shapes of parts. Present study is focused on investigation of part asymmetry on the forming behavior of the parts formed using SPIF process. Wall angle as an asymmetry is considered for forming of the pyramidal frustrum. The wall angle is varied from 50 o to 65 o and subsequent forming forces are recorded using force dynamometer. It is observed that the increase in the wall angle for symmetric part results in increased formability to a threshold wall angle of 55 o , beyond which the formability of material decreases. For the asymmetric parts, the difference in the forming forces of forming different wall angles (50 o and 55 o ) is 28%. The difference in the forming force increases to 93.27% for part having wall angles of 50 o and 60 o . Furthermore, during forming of asymmetric part, it is observed that the maximum forces go on increasing till the wall angle reaches to 60 o followed by sudden decrease in the forming forces. When compared to forming of symmetric part under similar conditions, it is observed that the symmetric part reaches to its fracture limit earlier as compared to that of asymmetric part. The numerical simulation gives some clear insights in the forming behavior of the asymmetric parts. Furthermore, it is observed that equivalent plastic strain first increases, and then decreases considerably resulting fracture of part of wall angle 65 o .

“…They observed that formability increases with increasing tool diameter, and tool with hemispherical tip shows more promising results than flat-ended tool tips. Huang et al (2023) analyzed the modification in thinning rate of titanium samples in SPIF using FEM and Taguchi approaches. They concluded that the most crucial parameter was wall angle (WA), followed by tool size, step down and initial sheet thickness.…”

Purpose This paper aims to optimize the single-point incremental forming process variables for realizing higher formability in Inconel 625 components and to plot the forming limit diagram for Inconel 625 aviation-grade superalloy. Design/methodology/approach The formability of Inconel 625 components has been measured in terms of major strain, minor strain and minimum sheet thickness. Response surface methodology with desirability function analysis has been used to achieve maximum formability. The finite element analysis has been conducted at optimal parametric setting. Findings The derived forming limit diagram proves that the maximum forming limit for Inconel 625 is 57.5° at the optimal parametric setting, achieved with desirability of 0.995. The outcomes of finite element analysis conducted at optimal parametric setting show excellent agreement with confirmation experiment results. Practical implications Inconel 625 superalloy is frequently used in aircraft and other high-performance applications for its superior strength. Originality/value It has been suggested that to enhance formability, higher tool rotation speed, minimum step-size, larger tooltip diameter and higher wall angle must be used. Wall angle is the governing parameter among all the parameters.
