摘要
研磨加工的材料去除速率受到磨料、研磨液、工件材料等诸多因素的影响。本文采用分量处理法把影响材料去除速率的因素逐项分解,开展固结磨料研磨蓝宝石的实验研究,分析机械、化学及其耦合作用对材料去除速率的影响。结果表明:研磨液作用下的机械化学耦合能够有效提高材料去除速率,耦合作用对材料去除速率的贡献率可达34.18%。固结垫基体在接触摩擦力的作用下,可以实现材料的去除,但其对材料去除速率的贡献率约为5%。
The material removal rate of the lapping process is affected by many factors such as abrasives,lapping fluids,and workpiece materials.The component processing method is used to decompose the factors affecting the material removal rate item by item,and the experimental study on the lapping of abrasive sapphire is conducted to analyze the influence of mechanical,chemical and their coupling effects on the material removal rate.The results show that the material removal rate can be effectively enhanced by the mechanochemical coupling under the action of grinding fluids,and the contribution of the coupling effect to the material removal rate can reach 34.18%.The material can be removed by resin matrix of fixed abrasive pad due to contact friction.However,its contribution to the material removal rate is about 5%.
