摘要
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 making propeller error in grinding square aspheric optical elements is analyzed.Each rigidity index of two fixing methods of abrasion wheel axis is calculated,and then the influence of abrasion wheel axis fixing position on the processing accuracy.The experiment at each position is done.Different abrasion wheels and different processing parameters are used to do the grinding experiment.Finally,the abrasion wheels axis fixing position and the grinding processing parameters which can satisfy the processing accuracy of square aspheric optical element are obtained.
