Incremental sheet forming (ISF) requires no or partial dies for metal fabrication and is widely used small batch production. In this process, necking either suppressed delayed due to the localized nature of tool–sheet contact; hence, more strains than conventional stamping deep drawing are obtained. present study, two variations ISF, namely cold ISF (CISF) warm (WISF), compared. First, FEA mode...

Nowadays Single Point Incremental Forming (SPIF) is really a new technology of forming metal sheet after its formation and long development in about five decades. Although it was invented in, 1967 by Leszak, an American inventor, but the applications innovative have just been popular from 1990 because advance controlling technology. This especially adapted to small batch, unique or single produ...

Abstract. Incremental sheet metal forming (ISMF) is a viable method for fabricating complicated three-dimensional structures from metal. It characterized by localized deformation and effective both rapid prototyping low-volume manufacturing. ISMF technology suitable quick product development time with affordable tooling deforming difficult-to-form materials. Simulation of the process reduces co...

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 recent years, in order to reducing die design and manufacturing costs, Multi point forming technique has gained an increasing interest because of its high flexibility. In this process, the conventional fixed shape solid die sets are replaced with a pair of opposite matrices of controllable elements. In this paper, the fundamental principles of multi-point forming was described and the possib...
