摘　　要：工件的研磨过程对其研磨质量具有决定性的影响,研究工件精密研磨过程的轨迹和速度对于保证工件研磨后的质量和研磨盘的均匀性具有重要的意义。文中从运动学和几何学原理出发,建立了工件精密研磨过程的轨迹方程,通过将复杂的研磨运动简化为在中心距一定条件下夹具绕研磨盘中心轴的回转运动及夹具自身的回转运动,对工件上任意点相对于研磨盘的运动轨迹及瞬时速度进行了分析计算,并开发了相应的计算机仿真软件,对其运动轨迹曲线及瞬时速度进行了分析。结果表明,在一定条件下,研磨盘会得到均匀磨损,工件的研磨质量也得以提高。计算机仿真技术的应用,为分析工件研磨过程的规律提供了可能,是一种简便有效的分析方法。The lapping process of the part has a significant influence on the lapping quality, therefore it is of great significance to study the path and velocity of lapping process for guaranteeing the lapping quality and uniform wear of lapping plate. In this paper, based on the kinematics and geometry principle, a path equation was established. The complicated lapping process can be converted into two rotation movements, i.e. the movement of part against the center of lapping disk and rotation of fixture around its center. The relative path and relative speed of random point of the part against lapping plate were also analyzed and calculated. The computer simulation software was developed for figuring the path curves and instantaneous speed of the lapping process. The results show that the lapping plate can wear uniformly and the lapping quality can be raised. The application of computer simulation software provides the possibil- ity to analyze the lapping principles. It is a simple, convenient and effective method.
