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

为实现无技能镜面磨削，本研究围绕以下五个方面进行了研究：1)砂轮工作面形在线测量系统的推广；2)磨粒刃口密度量化方法的建立；3)磨粒刃口分布随修整变化的把握；4)连续刃口间距量化方法的建立；5)微泡供给冷却液净化方法的开发。通过实践检验，弄清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。从结果看，无技能镜面磨削向实现又迈进了一步。

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.
