Abstract
Deep drawing is one of the most important forming process manufacture, in which a conversion of flat sheet metal formed into desired shape and size by subjecting the sample to a plastic deformation. The control of physical and geometric parameters is mandatory to reduce defects and achieve a height quality of drawn product. Aluminum alloys sheet forming have become key factor for product cost reduction and a quick technological development in many manufacturing areas like aerospace, automobile and electronic industries. Friction is one of the geometrical parameters which effect deep drawing process. It is important to control friction between tools and blank. Therefore, a focus on highlighting its influence on the formability was studied. In this work, friction between work piece and tools was studied, in predicting cylindrical cup deep drawing manufacture of AA2198 Al-Li alloy sheets, in order to investigate the influence of friction on the quality of the final product.Finite element analysis is used for this research. A 3D model was simulated using the FE-package ABAQUS software with a combination of Taguchi method. Relying to the results and discussion, it can be concluded the best combination.
