in the following putting way of billet. 1) Loading pathⅠ. Put the billet along x axis; the y axial protrusion is formed via lateral extrusion at the initial forming stage; and the y axial cavity is formed via lateral and backward extrusion. 2) Loading path Ⅱ. Put the billet along y axis, the x axial cavity is formed via lateral and backward extrusion. The differences between the two loading paths......
