在动力齿轮珩磨过程中，珩磨轮齿面磨料颗粒的随机分布是影响高质量淬火齿轮加工性能的主要因素。为了研究活性磨粒在工件齿轮上的微刃切削性能，通过获取珩磨轮齿的位置、方向和数量等随机分布状态，将实际珩磨过程简化为啮合区域单元中活性磨粒随机分布的微刃切削模型。结果表明，虽然活性磨粒分布在不同的位置，但它们都经历了三种类型的材料去除-滑动摩擦，犁地和切削-使齿轮珩磨过程具有研磨，研磨和抛光的组合加工特征。第一次接触的活性磨粒对被加工工件产生高的珩磨力、高的材料去除效率和较差的表面粗糙度，而后一次接触的活性磨粒则相反。位错角影响切屑形状和出屑方向，当位错角为135°时，珩磨力和材料去除效率最高。在给定的接触面积内，活性磨粒数越多，材料去除效率越高。
In power gear honing, the random distribution of abrasive grains on the tooth surface of the honing wheel is the main factor that influences the machining performance of high-quality hardened gears. In order to investigate the micro-edge cutting performance of the active abrasive grains on the workpiece gear, the real honing process is simplified into a micro-edge cutting model with random distribution of active abrasive grains in the cells of the meshing area by obtaining the random distribution states such as the position, orientation and quantity of the honing wheel teeth. The results show that although the active abrasive grains are distributed at different locations, they all experience three types of material removal—slip rubbing, plowing and cutting—allowing the gear honing process to have the combined machining characteristics of grinding, lapping and polishing. The active abrasive grains in first contact produce high honing force, high material removal efficiency and poor surface roughness on the machined workpiece, while the latter ones have the opposite effects. The dislocation angle affects the chip shape and chip discharging direction, and the highest honing force and material removal efficiency is achieved with a dislocation angle of 135°. The higher the number of active abrasive grains in a given contact area, the higher the material removal efficiency.
