Abstract
The effects of conditioning ring groove shape at polishing using conditioning ring type polishing machine have not been fully elucidated. In this research, we aimed at optimizing conditioning ring groove shape and improving polishing performance. In this paper, we carried out the image processing using the transparent polishing machine and investigated the relationship between the pixel value and the concentration of abrasives. Using the above relationship we varied the conditioning ring groove shape and compared the concentration of abrasives between work and surface plate.
