Out of all traditional process like casting, cutting, forging, forming etc. sheet metal forming is special case of deformation process in which sheet metal work is formed. Curling is a process of converting flat sheet metal into required curved radius surface with applying pre-determined force on press tool, having curl die. Generally, sheet metal formed in press tool with required curl profile die arrangements. The main aim of this project work is design and finite element analysis of curling tool. The curl tool is designed for curling sheet metal of thickness 1.5mm, 2mm and 2.5mm. Based on material properties of sheet metal, radius of curl required and press ton efficiency, Design of curl tool has been done analytically. With these design calculations, 3D modeling of curling tool is done. The finite element analysis carried out by applying appropriate boundary conditions. Then results ofequivalent (Von-Mises) stress and total deformation are evaluated and verified. The software packages used are Solid Edge ST7 for modeling of Curling tool and ANSYS Workbench 14.5 (Structural) for Preprocessing, Solving and Post processing of curling tool.
