摘要: 基于光栅平行磨削的加工方式,分析磨削参数对轴对称非球面表面粗糙度的影响,揭示轴对称非球面表面粗糙度的分布规律。研究砂轮与工件加工过程的干涉现象,阐述其对轴对称非球面表面波纹度的作用机理并提出影响其分布和大小的主要因素。结合磨削实验表明,垂直磨削方向的表面粗糙度明显比平行磨削方向上的大且数值呈现中部小、边缘大的分布特点。砂轮振动和插补步距分别是平行磨削和垂直磨削方向上表面波纹度产生的主要因素。Abstract: Based on the grate parallel grinding method that applied to large axisymmetric aspheric lenses manufacturing, the grinding parameters influencing the surface roughness are investigated and the distribution of surface roughness on axisymmetric aspherics is researched. Analyzing the interference between grinding wheel and workpiece, the influence mechanism of the interference on waviness error is established and the main effect factors are proposed. The grinding experiment results show that, the values of surface roughness in vertical grinding direction are much larger than that in parallel grinding direction. The values of surface roughness at the center of workpiece are the minimum, while the maximum values appear on the edges. The grinding wheel vibration and interpolation pace are the main affecting factors in parallel and vertical grinding directions, respectively.
