ABSTRACT
Metal blanking is a widely used process in high volume production of sheet metal components. The main objective of thispaper is to present the development of a model to predict the shape of the cut side. The model investigates the effect ofpotential parameters influencing the blanking process and their interactions. This helped in choosing the process leadingparameters for two identical products manufactured from two different materials blanked with a reasonable quality on thesame mold. Finite Element Method (FEM) and Design of Experiments (DOE) approach are used in order to achieve theintended model objectives. The combination of both techniques is proposed to result in a reduction of the necessaryexperimental cost and effort in addition to getting a higher level of verification. It can be stated that the Finite ElementMethod coupled with Design of Experiments approach provide a good contribution towards the optimization of sheet metalblanking process.
