Notes:
Based on the magnetorheological (MR) effect of abrasive slurry, the particle-dispersedMR fluid is used as a special instantaneous bond to cohere abrasive particles and magnetic particlesso as to form a dynamic, flexible tiny-grinding wheel to polish optical glass, ceramic and otherbrittle materials of millimeter or sub-millimeter scale with a high efficiency. Experiments wereconducted to reveal the effects of different process parameters, such as grain sizes of abrasiveparticles, machining time, machining gap between the workpiece and the rotation tool, and rotationspeed of the tool, on material removal rate of glass surface. The results indicate the followingconclusions: material removal rate increases when the grain size of abrasives is similar to that ofmagnetic particles; machining time is directly proportional to material removal, but inverselyproportional to material removal rate; machining gap is inversely proportional to material removal;polishing speed has both positive and negative influence on material removal rate, and greatermaterial removal rate can be obtained at a certain rotation speed. In addition, the difference of themachining characteristics between this new method and the traditional fixed-abrasive machiningmethod is analyzed
