Abstract

Sheet metal bending processes is a process which force is applied on a piece of sheet metal in order to modify its geometry structure. The force causing it to bend at desired angle and shape between die and punch. However, defect during the bending process cause by die and punch such as scratching, high percentage of deflection and changes in the physical characteristic of the sheet metal usually occur. Hence, the die and punch for sheet metal bending is being designed and developed by using SolidWorks in order to minimize the defect occurs. Following by that, finite element analysis (FEA) with commercial software, ANSYS, computer basedsimulation is being used to simulate the sheet metal bending. After that, the results from the simulation are compared with the existing U-bending experiment results due to the differences between real life conditions and ideal conditions. Besides, the study of the principle variables of the sheet metal bending is being carried out. These variables include mechanics of deformation such as stress, strain and force concentration in the sheet metal.
