Skill-free Mirror Grinding Method Based on In-process Measurement of Grain Cutting-edge Density

为了实现无技能镜面磨削工艺，本研究探讨了五个研究主题：1）砂轮工作面轮廓在线测量系统的推广; 2）磨粒刃口密度定量化方法的建立; 3）掌握修整过程中磨粒刃口分布的变化; 4）建立了连续切削刃间距的量化方法。5）发展了微气泡供给的冷却液净化方法。通过这些试验，阐明了磨削过程与刃口分布变化之间的关系，实现了磨削冷却液管理的新方法。从结果来看，无技巧镜面磨削的实现又前进了一步。

In order to realize the skill-free mirror grinding process, five research themes are examined in this study : 1) Generalization of on-machine measurement system of working surface profile of grinding wheel, 2) Establishment of the quantification method of the grain cutting-edge density, 3) Grasp of the change of the grain cutting-edge distributions with dressing, 4) Establishment of the quantification method of successive cutting-edge spacing, 5) Development of the coolant purifying method with the micro-bubble supply. Those practical examinations have clarified the relationships between grinding process and the change in the cutting-edge distributions, and realized the novel management method of grinding coolant. From the results, the skill-free mirror grinding has advanced one step to realization.
