Abstarct: Bulk forming of sheet mextal, often a combination of bulk forming and sheet mextal forming process in which the material flow is performed in three dimensions. Process for manufacturing flanged bush traditionally by use machining carried out. This process was not only time consuming, it produces a lot of waste. Recycling process is often associated with cost. An alternative to this method can be used in combination with methods for forming sheet mextal is Bulk forming. The combination of these methods, advantages such as being accurate dimensions of the final piece, reducing the final machining, speed up production, better product properties due to the difficult material. In this thesis study on the construction of the bush flanged on the sheet of aluminum alloy AA3003, using bulk forming of sheet mextal is considered. Initially, one of the most important issues that need to be taken into consideration, the design of the die. In mechanical and geometric form must be designed so that in addition to proper flow of materials, the forces forming is not tolerated and failure. In this regard, the bush flange profiles for the production of standard punch and the mold cavity and the mold core into a pressure ring, was designed and implemented. The pressure ring design, simulation test was conducted with relations theory in the design, dimensions pressure ring was calculated by putting different pressure forces. In the next step, tensile test and experiment bush flange forming process was conducted. Then, the samples were given shape and hardness test. Hardness test on the samples shows in the flanged bush, the relatively high hardness and little difficulty is created in the wall. Finally, to determine the accuracy A the experimental results were compared with simulations.
