Surface quality is one of the key parameters in Multipoint Incremental Sheet forming (MPIF). This work focuses on finding the factors influencing surface quality in MPIF. Three different parameters namely speed, feed and step depth are considered for the study. The effects of the above input variables on surface quality was investigated by Taguchi’s design of experiments and finally the optimum input parameters combination for minimum surface roughness is found. The most influencing parameter is found to be step depth followed by speed and feed. The findings were validated by a confirmation test.

“…In addition, the 3003 series aluminum alloys are extensively practiced in heat sinks, radiators, power battery enclosures, automotive heat shields, fuel tanks, water tanks, automotive skid plates, battery explosion-proof valves, battery covers, automotive interiors, signs, cans, medical equipment, etc. For modeling the sheet metal forming numerical simulations, knowledge about the selected material's flow behavior is necessary [1][2][3][4][5][6][7][8][9][10][11]. In detail, the stress-strain (SS) curve can represent the material flow behavior and lead the material engineers to choose the appropriate test conditions for conducting the experiments.…”

The single-point incremental forming process has witnessed significant advantages in automobiles, aerospace, and medical applications in recent years because of its flexibility in manufacturing complex shapes. In detail, the components are produced only using the toolpath, which is guided by computer-aided manufacturing software. However, during the forming process, the parts might experience fractures, which could heavily impact the formed part's geometric accuracy. The main purpose of this study is to analyze the formability of an AA3003-H18 aluminum alloy material in the SPIF process; for this purpose, the material properties are extracted from the experimental simple tensile test in three directions corresponding to the material rolling direction. At first, a simple tensile test is modeled and estimated the material properties for conducting the numerical simulations. Second, the real-time experiments of the SPIF process in terms of predefined forming conditions are performed, and then the surface roughness was measured to check the surface quality of the formed parts. Then, the formed parts are scanned using a 3D ATOS scanner and compared against the desired computer-aided design (CAD) model. Eventually, the numerical results are discussed in comparison with the experimental outcome and displayed a significant correlation toward the expected results. This results comparison communicates that the introduced finite element (FE) model can be adopted for investigating the appearance of thinning location, thinning reduction, distributions of stress and strain. The overall results show that satisfying material formability in better surface finish and geometric dimensional accuracy can be accomplished when the forming conditions are designed appropriately.

“…Application of Aluminum Alloys is prevalent in these processes due to its unique characteristics such as lightweight and good formability properties. As a low-cost method, small-batch, and flexible forming of sheets without molds, SPIF has been utilized to manufacture small parts of the rocket engine [1]. In SPIF, the sheet is usually fixed in the working die, and a rotating forming tool pushes the sheet at each forming step results in the final desired profile, as shown in Fig.…”

Single point incremental forming (SPIF) is a choice of interest in many manufacturing industries due to its wide range of applications. Materials such as copper, aluminum, steel, and many others formed various complex shapes through this process. However, the forming process could sometimes result in process defects, which could strongly influence the formed parts' geometric accuracy. The twist defect is one of them, which incrementally twists the forming sheet with a small angle at each forming step. In this paper, twist phenomena in the SPIF process have been investigated both numerically and experimentally. In the experiment, Aluminum Alloy (AA5052) was used to form a truncated pyramid shape, and a room temperature tensile test has been conducted to achieve the material's tensile properties. Then, the material property used in the simulation study of the SPIF using LS-DYNA software, where twist defect, stresses, strain, and thickness distribution are studied. The results from simulation and experiment show significant similarity against the expected results and this conveys that the proposed FE model of the SPIF process can be used to investigate the presence of twist, distributions of stress and strain, and thinning locations in the formed part.
