The thesis uses the ring upsetting method to study the determination of the friction coefficient in volume forming. Use finite element analysis to determine a set of friction coefficient calibration curves, and use the ring upset test to determine the percentage change rate of the ring inner diameter. The relationship curve between the ratio and the compression percentage of the ring height. By comparing the curves, the friction coefficient between the mold material and the forming material is obtained. The friction coefficient between the 6A02CZ material and the steel was determined when the 6A02CZ material was volume shaped in the steel mold. The friction coefficients of the 6A02CS material in the absence of lubricants and lubricants were 0.325 and 0.3, respectively. Studies have shown that the method of combining the finite element method and the ring upsetting test is more suitable for the finite element analysis in plastic volume forming.
