“…Guzman et al 22 analyzed the relation between the forming force and part accuracy, and the results indicated that the forming accuracy could improve by decreasing the forming force. Hussain et al 23 proposed the concept of a stress ratio, and the forming defects could be controlled by selecting the proper parameters related to the stress ratio.…”

The deformation energy in single point incremental forming has an immediate impact on the processing cost, the heat and the wear effects between the tool and the formed material. Meanwhile, poor forming quality is still one of the largest challenges for the development and commercialization of this method. Therefore, the goal of this study is to search for the optimal working condition for lower energy consumption with better forming quality during the forming process. A Box-Behnken design for a cone parts forming process has been performed. The effects of four input parameters (step down, tool diameter, wall angle, and initial sheet thickness) on three outputs-deformation energy, surface roughness, and geometric error-have been investigated. With the target of minimal synchronization of deformation energy consumption, surface roughness, and geometric error, which are 1522.4 J, 0.97 mm, and 1.939 mm, respectively, in this case, four processing parameters were optimized with tool diameters as 16 mm, step down as 0.5 mm, sheet thickness as 0.57 mm, and wall angle as 65°. With optimization of deformation energy and surface roughness, in conjunction with geometric error compensation, an increased accuracy of the resulting parts can be obtained with minimum deformation energy and surface roughness.

Making use of ''optimal experimental design,'' the paper attempts to investigate individual and interactive effects of predictor parameters, namely tool size, pitch size, feed rate, spindle rotational speed, and blank thickness, on sheet formability in single point incremental forming (SPIF) process. For the sake of precision, a novel sensor system was developed and employed to detect crack as it initiates on SPIF test specimens. A novel benchmark for formability in SPIF was established by addressing normal strain along sheet thickness, maximum attainable forming angle, and the rate of variation in forming angle. The process was finally optimized in terms of maximum achievable formability and minimum processing time. Accordingly, high-speed forming (with forming speed of at least 5000 mm/min) was realized to be perfectly viable, whereas the sheet formability remains quite satisfactory (over 90% of the maximum value). The key role of high spindle speed (up to 3000 rpm) was also highlighted in this regard.

“…FEA are now widely employed for better understanding of the defects occurring in the formed component. Numerical model was used to examine defects exhibited in SPIF namely corner fold, pillow and wall by using shell elements (Hussain, Al-Ghamdi, Khalatbari, Iqbal, & Hashemipour, 2014). Another study examined the pillow effect by the aid of experimental and numerical simulation results .…”

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
