| Outline of Final Research Achievements |
In this study, we proposed the dry grinding of carbon fiber reinforced plastic (CFRP) using the dry ice jet blowing on a diamond grinding wheel surface in the grinding process. As a result, it was experimentally clarified that the dry ice jet controls the wheel loading due to grinding of CFRP to lead the extent of wheel life and the increase of ground surface quality rather than the normal dry grinding. Furthermore, it was confirmed that some carbon fibers on the ground surface were finely crushed in wet grinding.
