Abstract: The two-step method of calculating ODF (orientation distribution function) from pole figure as the basic principle was used to precisely analyze cubic system material texture. The Euler space was divided by 1° minimum unit. All of the divided spot's orientation density were calculated all over the orientation space. In addition, the corresponding analysis system was established. By means of the analysis system the textures of coldrolled and annealed IF steel specimens produced by Angang were calculated and were compared those with the sophisticated ODF calculation system by the Euler angle 5° minimum unit. The results show that the analysis system by the Euler angle 1° minimum unit can more exactly express the texture distribution than by the 5° minimum unit.
