- 2011-2013年度科学研究費助成事業（基盤研究（C））研究成果報告書 課題番号：23560262 研究代表者：松崎健一郎（鹿児島大学・理工学研究科・教授）BTA深穴加工におけるライフリングマーク発生減少について、実機の構造に基づいた詳細な解析モデルを提案し、実機の打撃試験などから物理パラメータの同定を行った。さらに、得られた解析モデルを用いた数値解析結果と、実機における加工試験での振動測定結果および加工穴の形状測定結果を比較し、解析モデルの妥当性および発生メカニズムの検証を行った。また、提案しているガイドパッド追加配置による防止対策について、数値解析および実機実験によってその効果を確認した。その他には、ガイドパッド曲率の影響、動吸振器による振動抑制対策の効果、工具回転型BTAでのライフリングマーク発生現象などについて検討を行った。BTA deep hole drilling is used for producing holes of high aspect ratio. In this process, a chatter vibration sometimes occurs and a rifling mark is formed on the surface of a hole. The rifling mark generating phenomenon was considered as a self-excited vibration caused by time delay. The analytical model was proposed considering the structure of the real BTA deep hole drilling machine. In the real machine, the boring bar is supported at the oil pressure head and at the intermediate support as well as at the base. The uncertain parameters are identified by the vibration test of the real machine. Furthermore, the stability of the self-excited vibration was analyzed numerically, and the result of numerical analysis is compared with the experiment. It is confirmed that the theoretical and experimental results agree well with each other. Also, the effect of a countermeasure by an additional guide pad is evaluated theoretically and experimentally.
