中文摘要：
磷酸二氢钾（KDP）晶体具有质软、脆性高,各向异性等不利于材料加工的特点,被认为是最难加工的光学材料。本文采用普通刚玉砂轮和金刚石树脂砂轮对KDP进行磨削试验研究,初步揭示了不同磨削工艺参数对磨削力和表面形貌的影响规律;通过理论计算得到了KDP晶体（001）晶面临界磨削深度,进而探讨了超精密磨削KDP晶体获得较好表面形貌的途径。
英文摘要：
As potassium dihydrogen phosphate（KDP） has several weak points such as being soft,brittle and anisotropic from the point of view of machining,it is the most difficult machining material used for modern optical components.The effect of different grinding parameters on grinding force and surface topography was preliminarily revealed by the experiment of grinding KDP with the ordinary grinding wheels made from corindon and diamond resin.Theoretical calculation on the critical depth in grinding KDP crystal was given.Ultra-precision grinding for better surface topography of KDP mono-crystal was explored.
