For the deep drawing of advanced high-strength steel DP1180 sheet material with 0.8 mm, the drawing limit measurement experiment was carried out by adjusting speed and blank holder force in the deep drawing system of servo press Komatsu HIF-60, and the limit drawing diameter of Ф54.50 mm and the limit drawing ratio of 2.07 for this sheet material were obtained by the drawing experiment at room temperature. Then, the limit drawing diameter under different blank holder forces, stamping speeds and lubrication conditions, and the LDR values under the corresponding process parameters were further studied by changing only a single variable, and the optimization scheme was designed by the orthogonal experiment. Furthermore, through the variance analysis, the primary and secondary order of influencing factors affecting the deep drawing process of advanced high-strength steel was obtained as follows: the blank holder force, the lubrication, the stamping speed, and the optimal combination of parameters was obtained with the blank holder force of 10 kN, the grease lubrication, and the stamping speed of 5 mm·s-1 by the range analysis. The verification experiment of the optimized parameter combination shows that the optimized deep drawing part has good forming effect without obvious defects, and the limit drawing diameter and the limit drawing ratio at room temperature is increased to Ф55.75 mm and 2.12, respectively.
