Opis

This book proposes sequential abrasive jet polishing (AJP) and annealing processes that can considerably improve the BMG surface finish. In addition, this book also takes into account optimal parameters for both the AJP and annealing processes based on the Taguchi s L18 and L8 orthogonal array experimental results, respectively. The experimental results show that using the optimal AJP parameters, the surface roughness (Ra) of the ground BMG can be significantly improved from 0.675 to 0.016 µm. After the AJP process, the surface roughness (Ra) of the polished BMG can be further improved from 5.7 to 2 nm within an area of 5×5 µm by using the optimal annealing parameters. Furthermore, this book also proposes both air-driving fluid jet polishing (FJP) and AJP process that can improve the surface roughness of N-BK7 optical glass. The surface roughness (Ra) of ground N-BK7 optical glass can be improved from 0.350 to 0.032 µm by using the optimal air-driving FJP parameters and improved from 0.350 to 0.018 µm by using the optimal AJP parameters.
