| Outline of Final Research Achievements |
We have developed a new polishing method that combines fixed abrasive polishing and Magnetic Abrasive Finishing (MAF) process, by forming a magnetic brush on the action surface of a conventional fixed abrasive tool using a permanent magnet and magnetic particles. This new polishing method was applied to the polishing of ceramic materials and Ti alloys, and it was demonstrated that an excellent finished surface can be obtained compared to the conventional fixed abrasive polishing method. It was clarified that the removal mechanism of this polishing method is a combined action of material removal with fixed abrasive and precision polishing / deburring with a magnetic brush.

| Academic Significance and Societal Importance of the Research Achievements |
高能率除去と精密仕上げを両立させるために，固定砥粒研磨と磁気研磨法を融合させた新しい研磨法を提案した．本加工法をセラミックス材料，Ti合金に対して詳細な検証実験を行い，加工圧力，磁性粒子の粒径などが加工特性に及ぼす影響について調べた．また，加工メカニズムを明らかにすることにより他の難削材に対する適用可能性も示すことができ，工業的・工学的に有用な知見が得られた．さらに，本加工法は固定砥粒工具に永久磁石と磁性粒子，遊離砥粒の追加のみで達成できるため既存の工作機械への適用が比較的容易であり，工業的有用性が高い加工技術であることを示した．
