Simulation Research on Double-Side Grinding Method with Variable Position Rotation

In this paper, a double-side grinding method with variable position rotation is proposed, which changes the motion mode of the workpiece in the fixed distance rotation grinding from the grinding principle, and realizes the irregular planar motion of the workpiece in the isolation dics at the same time as the rotation. That is, the movement trajectory of the workpiece rotation center relative to the grinding tool is the curve of the change. Different grinding principles fundamentally overcome some defects of traditional planar grinding methods. A prototype model of variable position rotation grinding is established, and the feasibility of the new method is verified by simulation experiments. The simulation data also further proves the time-varying nature of this grinding method in improving the grinding trajectory, the uniformity of relative velocity distribution of grinding and the superiority and diversity of the mechanical wear of the grinding mechanism and the ability to adjust the grinding trajectory.
