In order to know in what way the cutting temperature and cutting resistance influence upon sharpness of a tool used, the authors of this paper studied on the influences of the point angle of drills, feeding and cutting speed of them upon the cutting temperature and the cutting resistance and they obtained the following results：(1)In the case of drilling SS41, at the feeding speed of 0.1 mm/rev, the influence of the point angle upon the cutting temperature was very small, while at the doubled feeding speed, the \ninfluence revealed significant, especially at the point angle of 118°, rising of temperature being signincant compared with the case at 130°,　105°. \n(2)As to the torque and thrust, similar tedencies were seen. The influence of feeding speed was great, growing greater approximately in proportion to the feeding speed, while it also grew greater in proportion to the increase of the cutting speed, the cutting resistance revealing \nits minimum around the speed of 20 m/min regardless the variety of feeding speed. (3)The larger the point angle is, the greater is the torque and thrust and is the cutting \ntemperature, so the feeding should be made small when the point angle is fixed large．\n(4)The form of chips is good at the feeding speed of 0.1/rev, revealing the form of flow \ntype chips, especially it is most ideal at 180°. At the feeding speed of 0.2 mm/rev  and at the increase speed of 30 m/min and onwards, tear type chips are to be seen produced, resulting the increase of the cutting temperature and of the cutting resistance．(5)In the drilling operation, the quality of forms of chips and of flow of chips will influence greatly upon the cutting temperature and the cutting resistance, accordingly it is most \nessential for thｅ sake of tools lives and for the economy of cutting power, to fix the cutting condition, observing the forms of chips and flowing patterns of chips.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_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_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0451212X","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040363","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"532","subitem_subject_scheme":"NDC"}]},"item_7_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":"野添, 光夫","creatorNameLang":"ja"},{"creatorName":"NOZOE, Mitsuo","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"田中, 秀穂","creatorNameLang":"ja"},{"creatorName":"TANAKA, Hideho","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-28"}],"displaytype":"detail","filename":"AN00040363_v2_p83-88.pdf","filesize":[{"value":"3.2 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN00040363_v2_p83-88.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/7562/files/AN00040363_v2_p83-88.pdf"},"version_id":"5463de72-61dc-4b0c-9cf2-76ce3a92f6fb"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ドリル切削に関する研究 (主として切削温度について)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ドリル切削に関する研究 (主として切削温度について)","subitem_title_language":"ja"},{"subitem_title":"Studies on drilling (especially on drilling temperature)","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["36","5297"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-24"},"publish_date":"2015-06-24","publish_status":"0","recid":"7562","relation_version_is_last":true,"title":["ドリル切削に関する研究 (主として切削温度について)"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-20T05:00:21.129555+00:00"}
