蓝宝石不同晶面轴向超声振动辅助磨削特性研究
Study on Characteristics of Axial Ultrasonic Assisted Grinding of Sapphire with Different Crystal Surfaces
摘要
Abstract
AUAG test study was carried out on sapphire A-plane,C-plane,M-plane and R-plane, and the grinding characteristics of the four crystal surfaces of sapphire were compared with and with-out AUAG from the grinding forces,specific grinding energies,surface roughnesses and surface to-pography.The grinding forces,specific grinding energies and surface roughnesses of ultrasonic vibra-tion assisted grinding are decreased when compared with that of general grinding,the surface damage cracks are small and the surface quality is better.However,when the ultrasonic vibration was applied to the different crystal surfaces of sapphire,the reduction rates of the grinding forces,specific grind-ing energies and surface roughnesses are different,the reduction rates of C-plane are the minimum, the reduction rates of M-plane and A-plane are larger,and the reduction rates of R-plane are the maxi-mum.When ultrasonic vibration assisted grinding of four crystal surfaces of sapphire,the improve-ments effects of R-plane are the best,followed by the M-plane and A-plane,the improvement effect-ivenesses of C-plane are the minimum.This shows that the greater brittleness of workpiece material, the more obvious the effectiveness of ultrasonic assisted grinding on the machining quality.关键词
