“…Guzmánand Habraken 122 proved that shear across the thickness could dominate the failure mechanism, which makes the description of damage using only triaxiality inaccurate. Recently, Wu et al 123 proposed a modified FFL model combined with process parameters during SPIF process. All these parameters integrated to the modified FFL model derived by equivalent plastic principle have physical meanings.…”

The constant need to improve manufacturing processes and production methods, with the aim of making these processes more flexible and precise, and subsequently solving problems of conformity, quality of manufactured parts and productivity, drives manufacturers to develop original manufacturing techniques. The incremental sheet metal forming process, one of these novel techniques, has attracted a great deal of attention in recent decades. This paper presents a review of recent work done in this area and captures ideas for future work based on studies conducted by several researchers. A review of advanced investigations considering the following terms of interest: process, tools, formability, modeling and simulation is developed. Overall, it can be said that ISF process still requires further research to exploit the fabrication of new materials such as novel nanocomposites and Functionally graded materials (FGM). Test the performance of 4- and 5-axis CNC machines to manufacture industrial parts. Finally, apply new hybrid technics at the aim to improve the geometric accuracy, formability and the productivity of ISF process.

“…Materials such as aluminium alloys are widely used to manufacture automotive, aerospace and other components due to their good strength, low weight and formability. Therefore, the peculiarities of SPIF processes using these alloys have been extensively studied by researchers [ 13 , 14 , 15 , 16 ]. Based on the simplified proportional-load assumption, the fracture-boundary model, in contrast to a conventional neck, can represent the failure mode according to the AA1050-H111 failure mechanism [ 13 ].…”

During the single-point incremental forming (SPIF) process, a sheet is formed by a locally acting stress field on the surface consisting of a normal and shear component that is strongly affected by friction of the dragging forming tool. SPIF is usually performed under well-lubricated conditions in order to reduce friction. Instead of lubricating the contact surface of the sheet metal, we propose an innovative, environmentally friendly method to reduce the coefficient of friction by ultrasonic excitation of the metal sheet. By evaluating the tool-workpiece interaction process as non-linear due to large deformations in the metal sheet, the finite element method (FEM) allows for a virtual evaluation of the deformation and piercing parameters of the SPIF process in order to determine destructive loads.

The forces acting in the process of single point incremental forming (SPIF) change the geometry of the sheet metal. The tool-workpiece interaction process is non-linear due to the large deformations of the sheet metal, which determine the plastic behaviour, as well as the evolutionary boundary conditions resulting from the contact between the tool and the sheet. Instead of lubricating the contact surface of the forming tool and the sheet metal, an innovative environmentally friendly method to reduce the coefficient of friction by vibrating the sheet has been proposed. The finite element method (FEM) allowed a virtual evaluation of the deformation parameters of the SPIF process in order to determine the destructive loads. The FEM was chosen as a deterministic numerical tool to evaluate the set of defect parameters induced by forming forces. The paper also proposes a method for predicting the formation force using an artificial neural network (ANN), assuming that such a model is generalized to implicit data. In this context, an empirical analysis of the implementation of the ANN technique is performed.
