采用DEFORM-3D软件对无台阶端头轧件的成形过程进行了有限元数值模拟，并结合二次回归正交旋转组合设计法，研究了各工艺参数对无台阶端头轧件料头体积损耗的影响规律，得到了轧件料头体积的回归方程。研究表明，轧件的料头体积与轧制长度成正比，与展宽角成反比，在模具设计允许的条件下，宜选用较小的展宽角。通过轧制实验，验证了回归方程的可信度和影响规律的正确性。

The forming process of no-step-end workpieces was simulated with the software DEFORM-3D. The influence of process-ing parameters on the end scrap of no-step-end workpieces was analyzed by means of quadratic quadrature rotate combination design method to get a regression equation. According to the obtained research results, the end scrap is in direct proportion to the length of blanks, but in inverse proportion to the spreading angle. A smaller spreading angle is beneficial under the selected range. Finally the reliability of the regression equation and the correctness of the influence rules were verified by rolling experiment.
