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.

“…The FFISF experiment is carried out on the basic of the three-sheet ISF process [25] and the setup is shown in figure 1. The target sheet is formed under full-edge constraint and trimmed after deformation in CISF, while the FFISF puts the trimming procedure in advance by precutting and precise positioning.…”

Titanium alloy sheet metal shows promising applicability in the aerospace industry with excellent mechanical properties, while its limited room-temperature formability is essential to be improved by thermal-assisted methods, with expensive equipment and much energy consumption. In this work, the flexible free incremental sheet forming process is adopted to manufacture Ti6Al4V free-form surface panel at room temperature. The strain evolution and thickness distribution during this new process are also analysed through finite element methods to reveal the deformation mechanism. Experimental and simulated results show that this process has potential advantages in rapidly fabricating low-ductility sheet metal with complex shapes at room temperature by improving strain and thickness distributions.

“…Zhan et al [24] also demonstrated a higher formability of an AA2024-T3 sheet at higher tool rotational speed compared with that of conventional SPIF. Yoganjaneyulu et al [25] presented that the forming limit of the topmost sheet was maximum in the case of multi-sheet incremental forming of a titanium sheet, and it decreased towards the bottom sheets. Kumar and Maji [26] presented the estimations of the forming limit of aluminium alloy sheets during SPIF via the deformation instability method (Figure 3).…”

Traditional manufacturing operations require a long time and capital for prototype development and small batch production. Forming processes necessitate component specific and expensive dies since their preparation and design are time-consuming. In latest years, incremental sheet metal forming has acquired good attraction owing to its ability for small-batch productions and prototyping with generic tooling and short lead time. In this paper, a review of literature works has been presented describing investigations carried out on the formability of lightweight alloys, mainly Al alloys, Ti alloys and Mg alloys, during single point incremental forming (SPIF) process, considering the deformation mechanism, formability assessment techniques, forming limit curves, effects of influencing factors, and the effect of heating.
