Based on a comprehensive analysis of the basic characteristics and mechanical properties of the deep drawing process with less waste material, the law of flow of the metal when the deep drawing of the square part is adopted is analyzed. A method to optimize the coefficient of the edge pressure is proposed. The results of the optimization are in good agreement with the experimental results, which provide important parameters for the design of deep drawing of square billet and the design of the die.
