The die geometry can affect the wire-drawing stress in the deformation process. In this Final Project the variation of die angle, reduction ratio, and bearing length are the case to be tested. The purpose of this final project research is to perform theoretical and simulation analysis to find the influence of variation of die geometry on wire-drawing stress using uniformdeformation energy method and finite element method. Aluminium-3003 is used in this study, this material is one type of aluminum which is often used for commercial purposes because of its good formability and suitable for cold working. ANSYSWORKBENCH v18.2 is used to perform the simulation process. Wire drawn at a reduction ratio of 0.1; 0.15; 0.2; 0.25; and 0.3 with die angle of 6o, 8o, 8.5o, 9o, 9.5o, 10o, 15o. The bearing length tested were 0.6 mm, 0.8 mm, 1 mm, 1.2 mm, 1.4 mm. The results of the experiment showed optimum angle on aluminum-3003 for a reduction ratio of 0.1; 0.15; 0.2; 0.25; and 0.3 is 8o, 8,5o, 10o, 10o, 15o respectively. The larger the die angle the greater the maximum stress occurs in the deformation process with the maximum difference about 33% , and the smaller the die angle the longer contact area that occurs during the deformation process. For a large reduction ratio the wire-drawing stress is large, but at low reduction ratios there can be nonuniform deformation that causing different stress value at each point. Bearing length also affects wire drawing stress with the largest difference 2.6269% of the practical bearing length 1 mm. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini!
