| Outline of Final Research Achievements |
In this study, we aim to development the CFRP processing machine to solve the problems which CFRP drilling process counter as burrs, delamination and short tool life. In order to reduce burrs in processing, grinding wheel are used instead of the conventional drilling tool. The workpiece fixture jig that can apply hydrostatic pressure is developed, and used in all processing experiments. A hybrid feed mechanism compatible with constant pressure and constant feed was mounted on the tool axis of a CFRP processing machine.
