局部磨削回火烧伤 localized grinding temper
The ratio of them usually retained stated, but when grinding burn happened, the ratio changed. It can be judged whether grinding burn happened using this grinding temperature or power which could be gained through calculation or experiment.
利用磨削过程中法向磨削力和切向磨削力间的变化关系进行磨削烧伤点的预测,给定条件下两者间比值一定,当发生磨削烧伤时,比值产生变化,根据此时的磨削用量,经实验测量或理论计算得到此处的磨削温度,并以此点的磨削温度或磨削功率作为判断磨削烧伤是否发生的依据。

Furthermore, the novelty process method can diminish roughness values and ground burnout obviously.
实验结果表明,随着加工循环次数的增加,表面微观形貌由方向一致的沟槽过渡到随机的、无方向性的微细凹坑,表面粗糙度值明显降低,喷射加工能减轻或消除磨削烧伤。
