thus resulting in the significant i

thus resulting in the significant increase
in diameter of the upper surface (Fig. 18c). This is so-called
‘‘mushroom shape” effect, which is one of main deformation characteristics
of cold rotary forging [16–18,20,21]. As the forging process
continues, the workpiece enters a steady deformation stage
and the profile of gear shape is gradually deformed

从而导致显著增加在上表面 (图 18 c) 直径。这就是所谓' 蘑菇形状"效应，它是一个主要的变形特征冷摆辗 [16-18,20,21]。作为锻造工艺继续，工件进入稳定变形阶段齿形轮廓是逐渐变形
