“…Li focused on the influence of elastic recovery on scratched grooves morphologies. He pointed that elastic recovery may be a significant factor that affects machined surface quality in the actual grinding process [20]. However, many of the present researches related to material removal are based on the observation and analysis after scratching and indentation tests, which means the factors such as the coupling effects of cracks in actual grinding process, and the variation of grinding parameters, could not be easily taken into consideration.…”

Because of the changes in cutting conditions and ultrasonic vibration status, the proportion of multiple material removal modes are of uncertainty and complexity in ultrasonic vibration-assisted grinding of optical glass. Knowledge of the effect of machined surface composition is the basis for better understanding the influence mechanisms of surface roughness, and also is the key to control the surface composition and surface quality. In the present work, 32 sets of experiments of ultrasonic vibration-assisted grinding of BK7 optical glass were carried out, the machined surface morphologies were observed, and the influence law of machining parameters on the proportion of different material removal was investigated. Based on the above research, the effect of surface composition was briefly summarized. The results indicated that the increasing of spindle rotation speed, the decreasing of feed rate and grinding depth can improve the proportion of ductile removal. The introduction of ultrasonic vibration can highly restrain the powdering removal, and increase the proportion of ductile removal. Grinding depth has a dominant positive effect on the surface roughness, whereas the spindle rotation speed and ultrasonic amplitude both have negative effect, which was caused by the reduction of brittle fracture removal.

The high quality of polished end face of photonic crystal fiber has a significant effect on coupling efficiency when photonic crystal fiber is used to couple with other optical devices. In order to obtain the smooth surface of the photonic crystal fiber, the end face polishing process of the photonic crystal fiber is analyzed using the finite element method in this article. Because there are many small air holes in the cladding of photonic crystal fiber, it needs better processing technology than that of ordinary fiber. The formation mechanism of cracks and the effects of cutting depth and grit tip radius on the processing results are researched, and this process is simplified as a single grit cutting a single hole wall and the cutting depth of grit with different diameters under certain lapping force is obtained by theoretical analysis. The simulation results show that finite element method can effectively simulate the end face lapping process of photonic crystal fiber, and that in the polishing process of photonic crystal fiber, the edge of hole wall is prone to the collapse area which is distributed along the circumference; cutting force and collapse area increase with the cutting depth and grit tip radius. For no collapse area generation, the maximum cutting depth of this photonic crystal fiber is less than the critical cutting depth of brittle plastic transition of ordinary fiber.
