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.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_8_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_8_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"532","subitem_subject_scheme":"NDC"}]},"item_8_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松崎, 健一郎","creatorNameLang":"ja"},{"creatorName":"MATSUZAKI, Kenichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"56752","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000080264068","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-31"}],"displaytype":"detail","filename":"23560262_松崎健一郎.pdf","filesize":[{"value":"418.8 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"23560262_松崎健一郎.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/11996/files/23560262_松崎健一郎.pdf"},"version_id":"9b38ffb8-8c27-4ee3-b6e3-7a8a0ec41466"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"BTA","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"深穴加工","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ライフリングマーク　","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"パターン形成","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"自励振動","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"BTA深穴加工における工具の振動抑制手法に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"BTA深穴加工における工具の振動抑制手法に関する研究","subitem_title_language":"ja"}]},"item_type_id":"8","owner":"18","path":["79"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-05-22"},"publish_date":"2015-05-22","publish_status":"0","recid":"11996","relation_version_is_last":true,"title":["BTA深穴加工における工具の振動抑制手法に関する研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-05-23T02:18:02.344397+00:00"}
