For the traditional single-side planetary abrasive lapping process particle trajectories passing over the target surface are found to be periodically superposed due to the rational rotation speed ratio of the lapping plate to workpiece that could affect the material removal uniformity and hence its surface quality. This paper reports on a novel driving system design with combination of the tapered roller and contact roller to realize the irrational rotation speed ratio of the lapping plate to workpiece in the single-side planetary abrasive lapping process for the improvement of surface quality. Both of the numerical and experimental investigations have been conducted to evaluate the abrasive lapping performance of the novel driving system. It has been found from the numerical simulation that particle trajectories would theoretically cover the whole target surface if the lapping time is long enough due to their non-periodic characteristics, which can guarantee the uniformity of material removal from the surface of workpiece with relatively high surface quality. The encouraging experimental results underline the potential of the novel driving system design in the application of the single-side planetary abrasive lapping for the improvement of the surface quality in terms of surface roughness and material removal uniformity.
对于传统的单边行星式研磨工艺，由于研磨盘与工件的合理转速比，发现经过目标表面的颗粒轨迹会周期性地叠加，这可能会影响材料去除的均匀性，进而影响其表面质量。本文报道了一种新型驱动系统设计，该设计结合了圆锥滚子和接触滚子，以在单边行星式研磨工艺中实现研磨盘与工件的非合理转速比，从而提高表面质量。进行了数值研究和实验研究，以评估新型驱动系统的研磨性能。从数值模拟中发现，如果研磨时间足够长，由于颗粒轨迹的非周期性特征，理论上颗粒轨迹将覆盖整个目标表面，这可以保证从具有相对较高表面质量的工件表面去除材料的均匀性。令人鼓舞的实验结果突显了新型驱动系统设计在单边行星式研磨应用中的潜力，可在表面粗糙度和材料去除均匀性方面提高表面质量。
