| 摘 要： | 系统地研究了光学研磨过程中,磨料粒径、载荷大小以及机床转速对钕玻璃表面及亚表面损伤的影响。结果表明,机床转速和载荷基本不改变材料表面粗糙度,而较大载荷或较低机床转速产生较大的亚表面缺陷,表面粗糙度和亚表面缺陷缺陷深度基本与最大磨料粒径呈正比,载荷增倍使亚表面缺陷与表面粗糙度的常数比值增加0.05。研究结果为钕玻璃加工工艺改进提供了参考依据。

| Abstract: | This paper investigated the influence of abrasive size,load and spindle speed in grinding process on surface/subsurface damage of Nd-doped phosphate glass experimentally.Results show that the surface roughness is affected little by spindle speed and load.Subsurface damage is much greater in low spindle speed or heavier load.Both surface roughness and subsurface damage are linear to the maximum nominal abrasive size.When the load is doubled,the ratio of subsurface damage to surface roughness increases by 0.05.All the investigating results provide essential foundation for optimizing fabrication techniques of Nd-doped phosphate glass. |
