砂轮振动将会使得光学元件表面产生周期性波动,从而降低后续抛光工序的加工效率,增加光学元件表面的中频误差成分,影响光学元件的使用性能。本文针对平行磨削方式,研究了砂轮周期性强迫振动下的工件表面形貌特征,分析了砂轮与工件表面的干涉现象,以及加工参数对加工表面波纹度特征的影响。研究结果表明:加工参数满足一定的条件下,工件表面振纹小于砂轮本身振动振幅,通过合理选择加工参数有利于改善工件表面波纹度,提高加工表面质量。Grinding wheel vibration has big influence on optical lens manufacturing.It not only reduces the efficiency of the following polishing procedure but also results in mid-frequency error on the surface.All the work in this paper expanded on the forced vibration of grinding wheel in parallel grinding of flat surface.The interference between wheel and workpiece is studied under different processing parameters.The research results show that waveness on the workpiece surface is decided by processing parameters;once the value of them is out of the critical points,the amplitude of the waveness on the workpiece surface will be lower than that of the wheel vibration.Therefore,reasonable choice of processing parameters is helpful to the improvement of the smoothness of the grinding surface.福建省自然科学基金计划项目(2012J05098)资
