| Outline of Final Research Achievements |
This research aims to develop “An on-machine Polishing CAM System Based on Five-axis Control” that can automate on-machine polishing using ceramics fiber brush for deburring. The tool paths for the polishing process were generated using the API of a 3D CAD Rhinoceros. And machining experiments were performed on convex arc surfaces, spherical surfaces, concave arc surfaces, and uneven arc surfaces of aluminum. As a result, it became clear that polishing can b achieved by controlling the brush with 5-axes. However, there were many variations in the control of the cutting depth due to unevenness, the rotation speed of the spindle, the feed rate, and it was not possible to select stable polishing conditions. Additionally, the application experiments with PCD tools and on-machine polishing tools were not conducted, and it remains as future tasks.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で得られた知見により，セラミックファイバーブラシを加工対象表面の法線ベクトル方向に５軸制御することで，加工表面の磨き加工が可能であることが示された．また，汎用の3DCAD(Rhinoceros)のAPIを用いることで，５軸制御の工具経路が生成可能であることを確認した．セラミックファイバーブラシのブラシ径の種類を増やし，さまざまな形状や材料を対象に磨き加工の最適な条件を見つめることで，ある程度の実用化が可能であると考えられる．結果として，これらの加工条件の選出やPCD工具，機上ポリッシングツールとの併用により，より実用的な磨き加工自動化の可能性を示す事ができた．
