摘要：
Structured surfaces play an important role in reducing the friction or dragging force of mechanical parts. In order to obtain an efficient grinding method for structured friction-reducing surfaces, a strategy for grinding the dimpled surface for friction-reducing by the grinding wheel with ordered embedded abrasive grain clusters was proposed based on the design theory of ordered arrangement of abrasive grains in grinding wheel. The arrangement design theory of the abrasive grain clusters on the grinding wheel is studied, and the relationships between the arrangement parameters of the grinding wheel and the dimpled surface of workpiece are analyzed.The grinding parameter conditions to realize the arrangement of the dimples and the relationship between the dimples and the geometry of abrasive grain clusters are discussed.The grinding parameter conditions to realize the arrangement of the dimples are discussed. The design theory of the ordered grinding wheel of abrasive grain clusters is studied, and the relationship between the arrangement parameters of the abrasive grain clusters of grinding wheel and the the dimpled surface of workpiece is analyzed. The grinding morphology and grinding mechanism of structured dimpled surface were verified through grinding experiment. The results show that the ordered grinding wheel with embedded abrasive grain clusters can be used to grind a structured dimpled surface with phyllotactic pattern, staggered pattern and array pattern.The arrangement and shape of the grinding structured dimpled surface depends on the layout design parameters of grinding wheel, the geometric shape parameters of abrasive grain clusters, and the choice of grinding parameters. © 2021, Editorial Board of Acta Armamentarii.
