• 論文の詳細を見る

• This paper deals with a boring bar used for boring operations in a speed range higher than the critical speed of the bar. One of the merits of this boring operation in a high speed range is that chatter-free machining can be theoretically obtained. In this study, it is shown that the bar must be designed to have external damping as many times as internal damping. Also, it has been proved experimentally that chatter-free operation can be realized. Another unexpected advantage is that in the experiment of boring aluminium work, chips are all broken in short lengths unlike to continuous tangly chips in conventional boring.
