This research aimed to prove the formability of advanced high strength steel (AHSS) by using servo press is better than by using traditional press. At first, a drawing die was designed and installed on a servo press. The drawing specimens were prepared by laser cutting from AHSS sheets. Parameters such as drawing ratio, forming velocity, die gap, forming path, and friction conditions were tested to analyze the formability of advanced high strength steel. The experimental results showed that a particular pulse motion provided by servo press could relubricate the specimen and improve the formability of AHSS. The finite element analysis software ABAQUS was used to simulate the drawing process to analyze the relubricating mechanism. The simulation results showed that the pulse motion could lower the coefficient of friction between specimen and die, and also explained why the relubricating mechanism could improve the formability of AHSS. This research showed that the formability of AHSS by using the servo press with pulse motion is better than by using the traditional press.
