摘要
对陶瓷磨削时临界磨削深度和临界磨削力模型进行了改进,得到二者的理论值,并以氟金云母陶瓷的有限元仿真研究为基础,通过分析不同磨削深度和磨削速度对工件磨削表面形貌、磨削力及磨削力比产生的影响,得到氟金云母陶瓷磨削延脆转变的临界磨削深度、临界磨削速度及临界磨削力。
The models of critical grinding depth and critical grinding force in engineering ceramics grinding are improved,thus, their theoretical values are obtained. Based on the finite element simulation of gold mica, the critical grinding depth,the critical grinding speed and the critical grinding force of brittle-ductile transition of gold mica grinding are obtained by analyzing the surface morphology, grinding force and grinding force ratio under different grinding depth and grinding speed.
