摘　　要：为了去除结构化外圆沟槽减阻表面在磨削加工过程中产生的边界隆起毛刺等缺陷,改善沟槽交界处的形貌,提高沟槽表面的减阻能力,采用超精研抛光法对外圆沟槽进行抛光整形。探讨油石压力、工件线速度与油石振荡频率对抛光整形效果的影响。结果表明:提高油石压力、增加工件的线速度与油石震荡频率能提高超精研抛光整形的能力。In order to remove boundary uplift burrs and other defects formed while polishing surface of the outer circular structural drag reduction groove, improve the appearance of the groove junction, and enhance the drag reduction capacity of the groove surface, the ultra-fine polishing method is adopted for polishing and shaping of the outer circular groove. This paper also discusses the influence of whetstone pressure, workpiece linear velocity and whetstone oscillation frequency on polishing and shaping. The results show that the effect of ultra-fine polishing and shaping can be improved by increasing whetstone pressure, workpiece linear velocity and whetstone oscillation frequency.
