The single point incremental forming (SPIF) is one of the dieless forming processes which is widely used in the sheet metal forming. The correct selection of the SPIF parameters influences the formability and quality of the product. In the present study, the Gurson-Tvergaard Needleman (GTN) damage model was used for the fracture prediction in the numerical simulation of the SPIF process of alum...

This paper presents the results obtained by numerical simulation regarding springback phenomenon of a U-shaped part manufactured from tailor welded stripes. The final shape of the formed part is seriously affected by springback phenomenon. This paper work is trying to prove the important role the metal sheet thickness on the springback effect. The U-shaped part has different springback values f...

The present paper proposes a numerical-experimental comparative study on the single point incremental forming process. A DC04 steel sheet with thickness of 0.6 mm was used for both numerical simulation using finite element method and experimental research. type trajectory spiral finished part obtained truncated cone-shaped part. analysis program Ls-Dyna. simulations were performed in several va...

Single point incremental forming is one of the most intensely researched die-less manufacturing process. This process implies usage a CNC equipment or serial robot which deforms sheet metal with help relatively simple tool that follows an imposed toolpath. As every cold process, besides many given advantages it has also some drawbacks. One big drawback in comparison other processes low accuracy...

Abstract This article outlines the development of an elastically foldable, bistable diaphragm geometry that enables increase in compression volume compressors compared to use flat diaphragms. Using a Finite Element Model (FEM) ABAQUS/Standard, several membrane geometries (truncated cone, and dome) were calculated analyzed with regard their elastic deformation. Selected produced using Single Poi...

As incremental forming is a relatively new sheet metal process, very limited analytical and finite element prediction models are available in literature to study the process mechanics improve its performance. Thus, most studies involve many trial-and-error iterations optimize processing conditions order take advantage of high flexibility material formability. However, reducing efforts utmost im...

Single point incremental sheet metal forming is a sheet metal forming process that forms products without the complex dies and tools with low cost. In this study, the incremental sheet metal forming process has been experimentally investigated on the explosively-welded Al/Cu bimetal sheets. Also, the effects of process parameters, such as arrangement of layer`s bimetal, tool diameter and tool p...
