摘要： 为考察单向碳纤维增强陶瓷基复合材料(Cf/SiC)的磨削表面质量，使用树脂结合剂金刚石砂轮完成正交试验研究.通过极差分析获得砂轮线速度vs、磨削深度ap和进给速度vw对表面质量影响的主次顺序.正交试验结果表明:磨削深度对磨削表面粗糙度影响最大;随着磨削深度ap的增大，表面粗糙度显著增大;随着砂轮线速度vs的增大，表面粗糙度不断减小;随着进给速度vw的增大，表面粗糙度增大.最终根据试验结果及表面微观形貌对单向碳纤维增强陶瓷基复合材料的磨削机理进行深入的分析，对单向Cf/SiC磨削加工理论的机理揭示具有指导意义.

Abstract: To investigate the grinding surface quality of unidirection carbon fiber-reinforced ceramic matrix composites(Cf/SiC)， the orthogonal experiments were carried out by using resin-bonded diamond grinding wheel. In order to achieve the influence order of grinding wheel linear speed， grinding depth and feed speed on grinding surface quality， range analysis was adopted in this paper. The results indicate that: the grinding depth has maximum impact on the machining surface roughness; as the raises of grinding depth， the grinding surface roughness increases; as the raises of grinding wheel linear speed， the grinding surface roughness decreases; as the raises of feed speed， the grinding surface roughness increases. According to the result of orthogonal experiments， the best combination of grinding parameters was achieved. Based on the experiment results and surface topography， the grinding mechanisms of unidirection Cf/SiC were further analyzed， which supplies some useful technical reference for revaling the grinding mechanisms of unidirection Cf/SiC.
