Abstract
In order to obtain the influence law of friction on setting position of billet in the blade precision forging process, metal flowing law of different billets in various friction conditions is simulated and analyzed by using a 3-D FEM code. The results show that when friction factor is smaller, the left of the die cavity is filled first. In order to obtain a qualified blade, initial billet should be placed a bit to the right of cavity. With the increase of friction factor, the left and right of the die cavity are almost filled simultaneously, which indicates that the setting position of billet in the die is more reasonable in this simulation condition. This study is of significance to technological design in the blade forging process.
