| 摘 要： | 本文研究了磁流变工作液中添加磨料种类、含量、粒度对其性能的影响,以及对磁流变效应微砂轮加工效果的影响。结果表明:添加磨料对磁流变效应的影响程度以氧化铈、碳化硅、金刚石、氧化铝的顺序增大,随着添加磨料含量增加、粒度增大,磁流变效应均被削弱。磁流变效应微砂轮加工微沟槽过程中,添加磨料对微砂轮加工性能的影响受到添加磨料对磁流变效应和磁流变效应微砂轮加工性能正反两方面的影响而出现最优加工效果。当磨料含量为3%时沟槽的宽度、深度和材料去除率都达到最大;当磨料粒度为W3.5时,加工沟槽的宽度最大;当磨料粒度为W7时,加工沟槽的深度和材料去除率最大。

| Abstract: | The authors studied the influence of material,content and grit size of abrasive on the property and machining effect of magnetorheological fluid(MRF).The results indicated that the influence of different abrasive materials on magnetorheological effect is arranged in an ascending order as :CeO2,SiC,diamond,Al2O3.All properties of the MRF decrease with the increase of abrasive content and abrasive size.So,in grinding micro grooves using a tiny grinding wheel based on MRF,there exists an optimum value of machi... |
