Due to a favourable strength-to-density ratio, aluminium and its alloys are increasingly used in the automotive, aviation and space industries for the fabrication of skins and other structural elements. This article explores the opportunities for and limitations of using Single- and Two Point Incremental Sheet Forming techniques to form sheets from aluminium and its alloys. Incremental Sheet Forming (ISF) methods are designed to increase the efficiency of processing in low- and medium-batch production because (i) it does not require the production of a matrix and (ii) the forming time is much higher than in conventional methods of sheet metal forming. The tool in the form of a rotating mandrel gradually sinks into the sheet, thus leading to an increase in the degree of deformation of the material. This article provides an overview of the published results of research on the influence of the parameters of the ISF process (feed rate, tool rotational speed, step size), tool path strategy, friction conditions and process temperature on the formability and surface quality of the workpieces. This study summarises the latest development trends in experimental research on, and computer simulation using, the finite element method of ISF processes conducted in cold forming conditions and at elevated temperature. Possible directions for further research are also identified.

“…The time period parameters are interested with the reason of the total running time of the tool is equal to the time of the last step that is not the time of the computer processes but the total time of the steps. Figure 7 Measure the bottom of the experimental models after releasing of the feature to define the depth at breakage for deducing the angle α by formula (1). The results are summarized in Table 3 4 COMPARISON OF SIMULATED AND EXPERIMENTAL RESULTS Table 3 displays the comparisons of experiment results and simulation results.…”

“…In SPIF, the application of a circular end tool (spherical end pestle with no cutting edge) in a special SPIF machine or in a conventional CNC milling machine. Controlled by a digital program, the noncutting circular end tool moves in following a predefined trajectory to deform the workpiece sheet metal that is clamped on a special feature to format desired shape [1]. Especially in the manufacture of artificial joints and cranes for each personal patient in medicine, these products have to be made of Titanium for elimination of corrosion and deterioration.…”

Hot Single Point Incremental Forming (HOT SPIF) is a new technology of forming a metal sheet at high temperatures, especially for hard, high strength materials that are difficult to perform at normal temperatures such as Titanium and other materials. The paper presents the application of simulation method to determine the ability of the deformation of Titanium sheet through the angle of deformation αmax of the lateral profile of the model under the influence of tool diameter D (mm), step in the direction z of the tool VZ (mm), the velocity of the tool Vxy (mm/min), the temperature T(0C). The content of this paper consists of the analyzing the influence of these 4 above parameters by building a finite element analyzing (FEA) model to determine the ability of deformation or the maximum lateral angle of forming and to compare the accuracy of FEM model to the one of Computer-aided design (CAD) model. The paper studies the influences of the 4 parameters to the ability to form of Titanium sheet by HOT SPIF.

Incremental sheet forming (ISF) process is a flexible manufacturing process to produce complex 3D products at reasonable manufacturing cost. An advantage of ISF is the improved formability than traditional sheet forming processes. The traditional sheet forming process requires dedicated tools (i.e. die and punch). However, ISF does not require any dedicated tool. In the current work, analysis of incremental sheet forming process through simulation has been done to predict the forming forces, energy requirements, effective stresses, and total forming forces on the sheet.The geometry accuracy of the product is found to be satisfactory. The results of simulation analysis may guide in developing an incremental sheet forming machine setup.
