摘要(中)

在塑性變形中旋鍛製程為常用來製造傘形齒輪的加工方法，由Deng [16]等人文獻中發現，旋鍛製程所產生的菇狀大小與傘形齒輪的節錐角的差異多寡會影響鍛造的填充性與加工成形力。故本文利用Lin 與 Han [14]所指出影響菇狀大小的三個因子(沖頭傾斜角、旋轉進幾率、高寬比)做不同搭配的有限元素模擬，來求得菇狀大小，進而使用反應曲面法來做進一步的簡化，求得適合的回歸模型，以利減少加工傘形齒輪上的不良率。

摘要(英)

Cold rotary forging is a common machining methodology to manufacture the bevel gears by plastic deformation. Deng et al. [16] observed that the size of the mushroom shape and the difference of the pitch-cone angle influence on the ability of fulfilling and the forging force. The finite element simulations could be set by the three following factors affecting the mushroom shape by Lin and Han [14]: (1) tilt angle of upper die (2) feed rate of rotary (3) ratio of height and width. The estimations of the mushroom shape by the different collocations of the above factors could be inducted by response surface methodology to get the proper mathematical model. It helps to reduce the defective rate of the manufacturing of the bevel gears.
