“…Ji and Park [23] also found that the circumferential strain was small enough to be negligible in SPIF process. Fang et al [24] measured the sheet deformation during the SPIF experiment and found that the meridional strain was 15-20 times larger than the circumferential strain. However, in the case when the circumferential curvature increases, the material deformation does not follow the plane strain assumption any more [19].…”

“…12 Experimental evidence that SPIF is limited by fracture without necking [55] shear in SPIF is considered as a positive factor to material formability when it is within a certain range. Fang et al [62] proposed an analytical model from their study to investigate the deformation mechanism and fracture behaviour in the SPIF technology. Both the bending effect and the strain hardening were considered based on the equilibrium approach.…”

Incremental sheet forming (ISF) is a relatively new flexible forming process. ISF has excellent adaptability to conventional milling machines and requires minimum use of complex tooling, dies and forming press, which makes the process cost-effective and easy to automate for various applications. In the past two decades, extensive research on ISF has resulted in significant advances being made in fundamental understanding and development of new processing and tooling solutions. However, ISF has yet to be fully implemented to mainstream high-value manufacturing industries due to a number of technical challenges, all of which are directly related to ISF process parameters. This paper aims to provide a detailed review of the current state-of-the-art of ISF processes in terms of its technological capabilities and specific limitations with discussions on the ISF process parameters and their effects on ISF processes. Particular attention is given to the ISF process parameters on the formability, deformation and failure mechanics, springback and accuracy and surface roughness. This leads to a number of recommendations that are considered essential for future research effort.

“…The 10 mm wide purple region to the edge of the blank was constrained to represent the clamping of the workpiece onto the fixture. The friction coefficient was set to be 0.05 for the contacts between the tool and sheet [28]. A backing plate is placed underneath the sheet to support the part.…”

In this paper, we report recent work in cranial plate manufacturing using incremental sheet forming (ISF) process. With a typical cranial shape, the ISF process was used to manufacture the titanium cranial shape by using different ISF tooling solutions with and without backing plates. Detailed evaluation of the ISF process including material deformation and thinning, geometric accuracy and surface finish was conducted by using a combination of experimental testing and Finite Element (FE) simulation. The results show that satisfactory cranial shape can be achieved with sufficient accuracy and surface finish by using a feature based tool path generation method and new ISF tooling design. The results also demonstrate that the ISF based cranial reconstruction has the potential to achieve considerable lead time reduction as compared to conventional methods for cranial plate manufacturing. This outcome indicates that there is a potential for the ISF process to achieve technological advances and economic benefits as well as improvement to quality of life.
