AbstractThe pendulum type processing technique is a manufacture way that the workpiece is rotating actively and the lap is slave drive from the workpiece under its gravity force and the pressure which comes from the pressure head. The rotational speed of lap is varied. Because the aperture size of the lap can be selected in the processing. So the processing efficiency is high. And this technique is commonly used in the grinding stage to remove a large margin, sub-surface damage layer and to smooth the mirror surface in the stage of polishing. Shown in the Preston equation, the removal function of lap is connected to the relative speed of lap_workpiece. Based on moment-equilibrium principle, a theoretical model is established about the lap which associated with the coherent parameters. Under the condition of the lap and the workpiece at different relative positions, the rotational speed of the lap and correspondence between the parameters is summarized and derived. The speed ratio of lap_workpiece increases with the increment of the eccentricity, and the actual rotational speed is determined by the workpiece's rotational speed, the size of lap and the force acting on the lap. The relationship of speed ratio between the lap and workpiece which impacts on the removal function is given at the last of the paper.; The pendulum type processing technique is a manufacture way that the workpiece is rotating actively and the lap is slave drive from the workpiece under its gravity force and the pressure which comes from the pressure head.
