环带抛光技术材料去除理论模型研究

为了更加完善环带抛光技术并指导加工，根据Preston方程建立了材料去除量的理论模型。考虑到环带抛光技术中的诸影响因素，如抛光盘与工件之间的转速比、偏心距及压强分布等参数，建立材料去除量与各影响因素之间的相互关系的数学模型。理论分析和实验结果表明：材料的去除效率随转速比和偏心距增加而增大，转速比越接近于1时，磨削越均匀；工件露边时，工件露出部分材料的去除效率急剧下降。通过对该理论模型中的相关技术参数研究来完善环带抛光技术，有效地提高抛光的效率及稳定性。

Study on material removal theoretical model of zone polishing technology

In order to improve the zone polishing technology, material removal theoretical model of zone polishing technology is founded based on Preston equation. Considering all influencing factors, such as rotating speed ratio, eccentric distance, pressure distribution between polishing lap and workpiece, the mathematical model which is about the relationship between the material removal and the influencing factors is established. The theoretical analysis and experiment results show that: material removal efficiency is increased as the rotating speed ratio and eccentric distance increase. When the rotating speed ratio is near to one, the removal distribution is more uniform. The material removal efficiency of edge is quickly reduced as the edge of workpiece holds out of polishing lap. The zone polishing technology is improved through researching the technological parameters of the theoretical model, and the polishing efficiency and stability are increased.
