Abstract：The deep drawing process of cylindrical cup was numerically simulated by ABAQUS to reveal the significant influence of friction properties of mold surface on thickness, strain and springback of the forming parts. On the surface of mold, there was an optimal distribution of friction properties. To improve the uniformity of part thickness, the optimal friction coefficients were acquired with μA, μC and μF of 0.12， μB of 0.26， μD of 0.09 and μE of 0.03，and the change of part thickness was only 27.99%. Based on optimal conditions, laser texturing and laser microtexturing composite texture technology were used to actively design and manufacture the friction properties on the surface of cylindrical mold, and the deep drawing experiments were carried out. The results show that after composite laser texturing, the maximum reduction rate of round corner at the bottom of forming parts is reduced by 46.56%, and the maximum growth rate of the thickness of flange is reduced by 30.71%. The thickness distribution of forming parts becomes more uniform with improved uniformity by 39.89%.
