In Incremental sheet metal forming process, one important step is to produce tool path, an accurate path of the main challenge incremental process. Various factors should be considered prior generation i.e. mechanical properties metal, holding mechanism, speed, feed rate and size. this work investigation studies have been carried out find different strategies control twist effect in final produ...

Within the Brite/EuRam project “DIGIMAN” a new optical measuring system for the assessment of sheet metal components in terms of shape accuracy and strain distribution has been developed. Based on the photogrammetrically measured geometric parameters of the object the system detects deviations from the desired geometry caused by springback and allows the strain analysis within critical stamping...

Roll forming process is used for manufacturing sheet metal parts by successive bending and creating the final shape with gradual deformation. In this article, deformation of a pre-punched sheet due to the roll forming process was studied. Two main defects in the roll forming process are ovality of holes and bow defect. The ovality of the hole is influenced by the process parameters including sh...

In this paper, Computer Aided Designing (CAD) in conjunction with Rapid Tooling is applied to design and produce forming tools (punch and die) for stretch-formed jewelry (generated on thin sheet metal on top of which jewelry patterns are raised with forming tools by stretching the sheet metal beyond its elastic limit. The work presents a parametric voxel based CAD paradigm for modeling of such ...

Due to a favourable strength-to-density ratio, aluminium and its alloys are increasingly used in the automotive, aviation space industries for fabrication of skins other structural elements. This article explores opportunities limitations using Single- Two Point Incremental Sheet Forming techniques form sheets from alloys. (ISF) methods designed increase efficiency processing low- medium-batch ...

Sheet metal forming is one of the major processes in manufacturing and is broadly used due to its high degree of design flexibility and low cost. In the sheet metal forming process, draw-in (planar movement of a sheet periphery) frequently occurs and is one of the most dominated indicators on the success of a forming process. Currently, monitoring and controlling draw-in during each stamping op...
