In the "Pressure lubricated deep drawing", the fluid pressure self-generated during working is an important key to its success. The hydraulic system used in the preceding experiments is reinforced to be able to perform experiments for various kinds of materials. Thus, the fluid pressure is controlled to some extent in order to pursue the pressure characteristics in detail. Results are as follows : (1) By developing the pressure formulae previously proposed, a new analysis for fluid pressure is presented, and its validity is proved experimentally. Thus, it becomes possible to predict the progress of the generated pressure exactly throughout the process. (2) To achieve better result, a guide how to control the pressure is shown. (3) By this method, we have accomplished a drawing operation with the drawing ratio of 2.83.
