分析了方形非球面光学元件磨削加工中产生四角塌边误差的原因,计算了方形非球面光学元件磨削加工时砂轮轴系两种安装方式的磨削系统刚度,讨论了砂轮轴系安装的位置对加工精度的影响,进行了砂轮轴系两种安装方式的方形光学元件磨削试验,以及不同砂轮型号、工艺参数的磨削试验,确定了能够满足方形非球面光学元件加工精度的砂轮轴系安装位置结构及磨削工艺参数。 The reason of the four-corner collapse error in the square aspheric optical element grinding process is analyzed. The grinding system rigidity of the two kinds of installation ways of the grinding wheel shaft in the grinding of the square aspheric optical element is calculated. Position of the grinding accuracy of the impact of the grinding wheel shaft mounted two ways of optical components grinding test, and different grinding wheel model, process parameters of the grinding test to determine the square aspheric optical components to meet the machining accuracy of the wheel shaft Department of the installation location of the structure and grinding process parameters.
