functions (ODF) of the samples are obtained. The characteristics of the crystallographic orientation, the grain structure and the grain boundary are analysed to find the effect of ultrasonic vibration on the microstructure and texture of the bond. The ultrasonic vibration will lead to exceptional refinement of grains to a micron level along the bond area and affect the crystallographic orientation......
J. Cent. South Univ. (2018) 25: 277-286 DOI: https://doi.org/10.1007/s11771-018-3736-5 Surface roughness prediction model in ultrasonic vibration assisted grinding of BK7 optical glass ZHAO Pei-yi... in ultrasonic vibration assisted grinding were also investigated, the theoretical model for surface roughness was developed based on the above analysis. The prediction model was developed by using......
