摘　　要：为探索利用小直径磨轮对陶瓷叶片型面进行数控展成型面超声磨削,通过对A l2O3陶瓷进行蠕动磨削和超声波辅助蠕动磨削对比试验研究,分析各加工参数对磨削表面质量的影响规律,优选工艺参数。结果表明:蠕动磨削和超声波辅助蠕动磨削所获得较低表面粗糙度值的优选工艺磨削参数均相同,但工艺参数对加工表面粗糙度的影响顺序不同;工艺参数对表面粗糙度的影响规律均相同,且存在着最优工艺参数,但在相同的工艺参数下,蠕动磨削所获得的表面粗糙度值一般均低于超声波辅助蠕动磨削。In order to grind the ceramic blade surface with the numerical control contour evolution ultrasonic grinding method using grinding wheel with small diameter, comparative experiments of Creep Feed Grinding （CFG） and Ultrasonic Assisted Creep Feed Grinding （UACFG） Al203 ceramics were carried out as to implore the influence of different process parameters on the machined surface quality and optimize the processing parameters. It＇s indicated the optimizing processing parameters axe the same to obtain lower surface roughness when CFG and UACFG, but the influencing order of processing parameters on machined surface roughness is different, and their influence laws are the same, and optimal processing parameters exist. The machined surface roughness obtained by CFG is lower than that by UACFG in most eases.
