| Abstract: | The trajectory of double-sided polishing is very complicated and has an important influence on the polishing process of the optical materials.The trajectory affects not only the processing efficiency,but also the surface quality.The movement of double-sided polishing process is discussed,and the mathematical model of the trajectory is established,which refers to any point of the planetary gear relative to the pad.By changing the parameters of the equation,the distribution of trajectories and the effect of different parameters are observed,and finally the optimal parameters of the trajectory are obtained.As the results shown,when the workpiece in the planetary gear keeps away from the center of planets,the radius ratio between planetary gear and top plate is 0.3,and the relative speed range between top plate and sun gear is 3~8,and the speed ratio range between ring gear and sun gear is in the time 1~4,the optimal trajectory is obtained. |
