Different angles-bond angle dislocation line charts. Figure 11 represents the cutting dislocation line and the bond angle. As the repeated cuttings on the workpiece surface are done by the numerous abrasive particles during the polishing process, in the entire cutting process, the abrasive particles with larger cutting angle produce bigger pits, while the following abrasive particles with smaller cutting angles continue to polish along the cutting trace. Therefore, certain depth is done on the workpiece material and the whole micro-cutting of abrasive flow polishing is achieved. a Dislocation lines with 0° cutting angles. b Dislocation lines with 5° cutting angles. c Dislocation lines with 10° cutting angles. d Dislocation lines with 15° cutting angles. e Dislocation lines with 20° cutting angles. f Dislocation lines with 25° cutting angles. g Dislocation lines with 30° cutting angles. h Dislocation lines with 35° cutting angles. i Dislocation lines with 40° cutting angles. j Dislocation lines with 45° cutting angles. (Note: the upper part of the key angle analysis, the figure in the atomic color: HCP BCC Amorphous structure Abrasive grain; the lower part of the dislocation line diagram, the figure dislocation line color: Stair-rod, Shockley, Hirth, Perect, Frank, Burgers vectors)
