        Generally it is needed to have a multi stage drawing operation to increase a drawing ratio. So, this study is about the hydraulic circuit design of the 3 stage deep drawing machine. As the drawing ratio is large or deep, the quality of deep drawing products are affected more by the force and velocity of the press cylinder. Therefore using the computer simulation, the pressure reponses which are related to the force and velocity of press cylinder are analysed, and the design of the hydraulic circuit are proposed. The results of simulation shows that it correspond to experiments and have good feasibility. Proposed hydraulic circuit can be used to improve the quality of a deep drawing products.
