摘　　要：单层电镀CBN砂轮通过电镀工艺将磨料固结在砂轮表面。通过严格的磨料粒径一致度控制,实现更高的砂轮品质是高端砂轮制造的关键技术。因此,建立磨料粒度及其分布与砂轮表面地貌特性之间的关系对砂轮设计及磨削质量控制将起到重要作用。针对单层电镀CBN砂轮提出了基于制造过程的数字化砂轮模型,可实现对砂轮生产制造过程中的每个步骤的仿真。通过对3种规格砂轮的建模与地貌测量,验证了模型的准确性和有效性。同时,通过该模型研究了磨粒直径标准差与砂轮微观地貌特征的关联机制,为砂轮数字化设计与质量控制提供了定量化依据。The single layer electroplated CBN wheels are made by joining all abrasive grains onto the wheel hub through electroplating processes. It＇s a key technology to achieve higher wheel quality by rigorous size consistency control for manufacturing high-end grinding wheel. Therefore, the understanding of relationship between the grain size and its distribution with the wheel topographical properties will be critical for the wheel design and grinding performance control. The ＂through the process＂ grinding wheel model is developed for single layer electroplated CBN each wheel fabrication procedure numerically. The accuracy and effectiveness o verified by modeling and measurement for wheels of 3 specifi abrasive diameter could provide deviation and wheel topographical properties quantitative basis for grinding wheel digital d wheels by lating the digital model is cations. In addition, the correlation of was studied through this model, which esign and quality control.
