Rolled Metal Characteristics • Residual stresses • Dimensional tolerances for cold-rolled sheet thicknesses +/- 0.1 mm to 0.35 mm (0.004 to 0.014 inch) • Flatness tolerances to within +/- 15 mm/m (3/16 inch/foot) for cold rolling, +/- 55 mm/m (5/8 inch/foot) for hot rolling • Hot rolling and sand casting produce similar ranges for Rout demonstrates that the rolling process is a bulk metal forming process, where metal flows plastically between two rollers, rotating in opposite directions, by which the thickness is reduced .mm thickness. Sheet metal rolling is a process of converting a sheet of metal into a complete hollow cylinder. The machine consists of three rollers; slip roll, pinch roll and a back roll. The rollers are made of mild steel shaft 1500 mm long and 90 mm in diameter. The whole system is mounted on a metal frame made from mild steel plate also .Human development in skill that pertain to technological understanding in quintessential for the success of excel- lence in metal forming and rolling operations [23,24]. A review of the trend and developments in metal forming (rolling) and the metal forming deformation process of rolling flat shaped metal products has been explored.

Rolling is a metal forming process where metal stock is passed through one or more pairs of rolls to reduce the thickness and change the cross section of the metal. . • These compressive stresses cause the rolled sheet to be wavy . Flexible rolling forming (FRF) is a novel forming method for manufacturing 3D surface sheet metal parts by using two integral bendable rolls. The rolls are adjusted to a particular bending shape and gap distribution. They force the sheet metal to produce a certain bending deformation in transverse direction and nonuniform compression in thickness .Design and Fabrication of Sheet Rolling - Free download as Word Doc (.doc / .docx), PDF File (.pdf), Text File (.txt) or read online for free.

This process of converting sheet metal to the desired shape consists of two operations: cutting to the required geometry and forming the desired shape. The former operation leads to rupture of the sheet, whereas in the case of the latter, the purpose is to plastically form the sheet. The research deals with the process of sheet metal cutting
