取固着磨料浮动研磨中的工件为分离体,对其进行力学分析,建立受力微分方程,求出其受力和运动规律,并结合已知的磨具运动,求出二者间的相对运动规律,根据它们的相对运动轨迹合理地设计磨料的密度分布,使磨具均匀磨损,避免了修整磨具的麻烦,节约了磨料,提高了加工精度,结合固着磨料高速研磨的优点,实现了低成本、高效率纳米级高速研磨. Take the fixed abrasive floating grinding workpiece as a separate body, its mechanical analysis, the establishment of force differential equations, to find the force and movement law, combined with known abrasive motion, find the relative movement between the two According to their relative motion trajectories, the density distribution of abrasive is reasonably designed so that the abrasive is evenly worn, the trouble of dressing the abrasive is avoided, the abrasive is reduced, the processing precision is improved, and the advantages of the high speed grinding of the fixed abrasive are realized, and the low Cost, high efficiency nano-scale high-speed grinding.
