The forming tool, primary start position and toolpath angle movement effect on the geometry accuracy “springback”, part C

Abstract

Incremental Forming process, IF is a technology for producing 3D-dimensional complex sheet profiles. The advantages of the process involve simple set tools, fixture and forming tool, shorter time for producing the pattern, and flexibility. While the main limitation of the process is the springback that represent geometry accuracy, the part profile precision limits the difficulty of forming toolpaths, including the wall angle. This work presents the forming toolpaths effect in the IF process. The supporting space and the product base dimension including wall angle is used to study the springback effect through the incremental forming process. Sheet metals Aluminium-A1025 are used for manufacturing the products. The research goals are to comprehend the springback defect behaviour which is affected by the supporting space-toolpath angle and the supporting space-product base ratios. The strain distributions and the thinning percentage of the final product section have been considered and analyzed in detail.

A study of effect the supporting space and tool path in sheet forming, thickness evaluation, part D

“…The study involved six series that consider the supporting space, the die radius and the forming tool path [12][13][14]. The paper presents the data and main results of a study for evaluating the thinning and the thickness distribution along axisymmetric product profile section.…”

“…The tool sets and the blank materials are represented in the application program "Ansys". The elements selection is considering the properties for each of them, as illustrated in detail in previous studies [12][13][14] and Table 2. The nonlinear analysis considers the process, and the friction coefficient, step size and the fixed parts involved within the boundary conditions.…”
