| Abstract: | In this paper, an expression about the rational axis clearance of high - speed shearing is put forward, which is an important influencing parameter on the section - quality of shearing process. The con elusion is drawn by referring to the related theory of fracture mechanics and plastic mechanics on crack tech nique, and the experiment demonstrates the correctness of the theoretic analysis. |
