| Outline of Final Research Achievements |
Shape and distribution of abrasive grain cutting edges on working surface of grinding wheel is a major factor affecting the quality of the finished surface. From this, features such as distribution of abrasive grain cutting edge extracted by image processing has been analyzed. However, it is difficult to extract only abrasive grains when there is no difference in hue, saturation, and lightness between diamond abrasive grains and other regions on the working surface of grinding wheel. Therefore, in the previous method using only image obtained with visible light, the grinding wheel that can be measured was extremely limited. In this research, we focused on the physical properties of diamond abrasive grains to solve the previous problem. We tested image processing using images obtained with visible light and with ultraviolet light . The results indicated found that abrasive grains can be analyzed for various grinding wheels
