| Abstract: | The UBET is used in this paper to calculate the force of forward extruding gear. On the base of studying the metal's plastic flow, the deformation region is plotted into 9 portions and the formulas of each portion are provided according to the character of its metal flow, and validated by experiment. |
| Keywords: | Gear Forward extrusion UBET |
