n.奧氏體變形

vt 奧氏形變.

During ausform finishing process of hardened gears, there is plastic displacement of metal on the tooth surface and the distortion of tooth profile . 在齒輪熱滾擠加工中,輪齒上的金屬在強制擠壓力的作用下沿齒面產(chǎn)生塑性流動,使齒形發(fā)生變化。

In this thesis, a new advanced technology, called ausform finishing, is first presented in our country for manufacturing hardened gears. 本文創(chuàng)新提出了用于硬齒面精加工的精密熱滾擠技術(shù)。

At last, the design of the prototype machine for ausform finishing process is carried out, and compensating measures of machining error are put forward. 最后，對熱滾擠加工設(shè)備樣機進行了設(shè)計，并提出了加工誤差的消減措施。
