“…The results from these investigations demonstrated that with increasing or decreasing of sheet thickness, surface quality improved. Optimization of sheet is important because with very large sheet thicknesses, outside form the range of values examined in majority of papers would start high challenge to form the parts with very high forming force and due to this surface roughness increase as shown with aluminum alloy (AA 3003-O) by Shanmuganatan et al [32] and with aluminum alloy (AA 1100) having thickness 4 mm by Fang et al [67]. This survey analyzed that influence of sheet thickness is reliable despite the effects of every sheet material may vary.…”

Literature has vastly advocated for incremental sheet forming as a significant process for formation of sheet metal components, because of its higher formability in comparison with the rest of metal forming processes such as deep drawing and stamping. Due to high formability of incremental sheet forming it becomes important to investigate the main factors, influencing the quality of forming products. However, less attention has been given to investigate the inconsistencies reflected often in determining the effect of multiple forming parameters and parametric interactions comprising of spindle rotational speed and feed rate, tool size and sheet thickness, sheet thickness and step depth. This study investigates the effect of various principal factors including tool type, tool size, sheet thickness, spindle speed, feed rate, step increment including and their respective interaction on surface roughness. Research data was collected by undertaking extensive literature review of previous studies on incremental sheet forming regarding surface quality. A quantitative one way analysis of variance (ANOVA) was employed to analyze the significance and contribution of factors influencing surface quality of sheet forming. The findings highlight the contribution of forming parameters and their combined interactions on surface roughness. Based on the empirical findings, this study derives implications for the optimization of tool type, parametric interactions among principal factors and their respective optimized operational range for incremental sheet forming.

“…FEA were successfully implemented to analyze stress and strain during the sheet deformation (Shanmuganatan & Senthil Kumar, 2012). Various studies have investigated the parameters like wall angle, tool diameter, incremental step size and material thickness critical in SPIF by the aid of numerical models (Arfa, Bahloul, & BelHadjSalah, 2012;Bahloul, Arfa, & Belhadjsalah, 2013;Shanmuganatan & Senthil Kumar, 2013). FEA are now widely employed for better understanding of the defects occurring in the formed component.…”

Single point incremental forming has shown immense potential in the manufacture of prototypes. The sheet metal deformation in this technique is carried out by a small hemispherical or flat tool that moves from the sheet periphery to the sheet center while also pushing the sheet down. Simulations of single point incremental forming can be a tedious task since the area required to be formed is large and the two sheet contact area is fairly small. The effect of tool however, affects the entire geometry by causing deflections and radial strains. Hence, it becomes essential to understand the effect of certain parameters that influence the simulation results for this forming process. The paper aims to study factors influencing the simulation of single point incremental forming process. It gives a description of techniques employed to simulate non-linear behavior of sheet metal forming along with the implicit and explicit methodology. Information on the selection of element type including Reduced Enhanced Solid-Shell element is presented. Techniques employed to avoid locking are also discussed. ARTICLE HISTORY

“…The major responses like wall angle, surface roughness and thinning of the sheet are evaluated. In addition to that, the study also includes scanning electron microscopic and energy dispersive X-ray spectroscopic microanalysis and process simulation using finite element modeling technique [14]. Ziran et al [15] showed that flat end tools provide better formability, part accuracy, and lower forming forces than hemispherical end tools.…”
