高周波振動複合加工による金属材料の微細加工に関する研究

　金属の穴加工において，ドリルの軸方向に40kHzの高周波振動を付加した実験を行った．その結果，高周波振動の効果により，切削抵抗の変動値の減少，切削屑の微細化が確認できた.

 This paper describes experimental investigation．In the drilling of the metal, the experiment by which the high cycle vibration （40kHz） was added to the drill was done．As a result, the decrease in the value of the cutting resistance was able to be confirmed by the effect of the high cycle vibration and confirm making cutting rubbish minute． Some results are presented in the from of parametric graphs and tables.
