摘　　要：金刚石磨具具有磨削效率高、使用寿命长、加工工件精度高等优点,广泛应用于航空航天、模具制造、电子器件、光学材料、医疗器件、石材加工等领域.磨具中起磨削作用的是出露的磨粒,磨粒突出结合剂表面的高度称之为出刃高度,磨具只有具备适宜的出刃高度时才能发挥最佳的磨削性能.因此,出刃高度的检测与调控技术对高性能磨具的制备至关重要.本文综述了金刚石磨具出刃高度的评价参数、检测方法及调控技术,分析了该研究领域中存在的问题,最后指明了未来研究的方向.Diamond grinding tools are widely used in aerospace, mold manufacturing, electronic devices, optical materials, medical devices, stone processing and other fields because of their advantages of high grinding efficiency, long service life and high precision of workpiece processing. The grinding function of the tools is realized by the exposed abrasive grain, the height of which from the surface of the bonding agent is defined as the protrusion height. Abrasive tools can only perform the best grinding performance when they have the appropriate protrusion height. Therefore, the testing and regulating technology of the protrusion height is very important for the preparation of high-performance grinding tools. In this paper, we reviewed the evaluation parameters, testing methods and control techniques of diamond protrusion height and analyzed the problems in the research field. Finally, we pointed out the future research direction of protrusion height test and control.
