研究了氧化铝缓进给磨削中砂轮磨损对过程响应和零件质量的影响。车轮工作表面的金刚石磨粒形成磨损平面，有时出现微破裂。随着金刚石磨粒磨损的增加，磨削力和磨削功率增加，但粗糙度降低。磨光轮磨光的钢筋的抗弯强度比磨光轮磨光的钢筋的抗弯强度降低更大。压痕断裂模型被用来解释接地棒的不同断裂行为。 对缓进给磨削实践提出了建议。

The effect of wheel wear on process responses and component quality in creep-feed grinding of alumina is investigated. The diamond grits in the wheel working surface developed worn-flats and sometimes microfractured. The grinding forces and power increased, but the roughness decreased with increased wear of diamond grits. The bars ground with as-dressed wheels exhibited a larger reduction in flexural strength than those ground with wheels with worn-flat grits. Indentation fracture models are employed to explain the different fracture behaviors of ground bars. Implications for creep-feed grinding practice are suggested.
