The temperature at the cutting point is a significant factor in any examination of the cutting mechanism of diamond grains in ceramic grinding. In this study, the temperature of the working grains on the diamond wheel just after cutting and the heat pulses produced by cutting grains in the surface layer of a ceramic are measured using an infrared radiation pyrometer, with the radiation transmitted through an optical fiber. The ceramics used as a workpiece are Si_3N_4 and SiC. The maximum temperature at 40 depth below the ground surface is approximately 500゜C, which is much smaller than that of the carbon steel. Since the conductivity of the ceramic is very small. The temperature of the working grains on a diamond wheel is greater than 1200゜C.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:61550095, 研究期間(年度):1986 – 1988","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「ファインセラミックスの研削温度測定」課題番号61550095\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-61550095/615500951988kenkyu_seika_hokoku_gaiyo/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢工学部","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00067745","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/search/?kw=60115996"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/search/?kw=60115996","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-61550095/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-61550095/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-61550095/615500951988kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-61550095/615500951988kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-10-28"}],"displaytype":"detail","filename":"TE-PR-UEDA-T-kaken 1990-2p.pdf","filesize":[{"value":"87.2 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-UEDA-T-kaken 1990-2p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/61502/files/TE-PR-UEDA-T-kaken 1990-2p.pdf"},"version_id":"5bf66eaf-dd99-4e96-a657-88e98e166459"}]},"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":"ファインセラミックスの研削温度測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ファインセラミックスの研削温度測定"},{"subitem_title":"Measurement of Grinding Temperature of Ceramics","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2845"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-10-28"},"publish_date":"2022-10-28","publish_status":"0","recid":"61502","relation_version_is_last":true,"title":["ファインセラミックスの研削温度測定"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T11:53:33.461395+00:00"}
