Simulation and modelling of sheet metal forming process are well common today in different industries (automotive, aerospace) several research centers regarding its huge impact for both on production reliability the lifecycle equipment, quality product. However, to obtain best configuration possible with inputs parameters achieve high level increasing durability tools needs some extra methods o...

In sheet metal forming, free deformation of the takes place frequently without contact with forming tools. The pre-straining resulting from leads to a surface roughening metal. It is assumed that has an influence on friction and wear behavior following process as well painting quality after manufacturing. this paper, numerical prediction based polycrystalline model first proposed predict effect...

For ̄ exible manufacture of a doubly curved sheet metal, a new sheet metal forming process is proposed that uses a movable punch set composed of two pairs of lower support punches and one upper centre punch. The process is characterized by ̄ exibility compared with the existing conventional processes because it does not require any complex-shaped die and the loss of material is minimized by unc...
