In order to make the observation as simple and direct as possible, the cut studied in the present investigation have all been made on the edge of revolving disk. The face of the disk has been polished and etched, in order to reveal the internal structure and the flow or deformation. The materials used as stocks for the cutting experiments were mild steel, rolled brass, cast iron, and aluminium alloy. The experimental cutting operations have been performed with ordinary carbon-steel parting tool and flattened edge tool, no lubricant being used. The observation of the cutting edge of a tool and the deformation of chip has been made by means of the microscope supported on the tool rest of the lathe. The magnified images of the cutting edge and chips have been photographed by means of the \"Ica universal kinamo.\" The picture were taken from 15 to 20 magnifications for widening the field, but by projecting them for desired magnifications, the mechanism of the action of cutting tools might be clearly observed. From these pictures it appears:- (1) In a brittle metal, such as cast iron, the chip is crushed with little distortion, and the form is very irregular. (2) In a ductile metal, such as an aluminium alloy or mild steel, the distortion of the chip is remarkable and a built-up edge is formed on the cutting edge of tool under a suitable speed and depth of cut, especially when a flattened edge tool is used a built-up edge is easily formed. In this case, the built-up edge is the actual cutting implement, the tool merely serving to support it.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA4415976000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京帝國大學航空研究所"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162779","subitem_source_identifier_type":"NCID"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Research Engineer of the Institute"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"ISHII, Sadamu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"422771","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA4415976.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA4415976.pdf","url":"https://jaxa.repo.nii.ac.jp/record/35783/files/SA4415976.pdf"},"version_id":"4b5616b2-bdba-4797-b78d-5b8ab7845aec"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Microscopic Kinematographs Applied to the Research of Metal Cutting.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Microscopic Kinematographs Applied to the Research of Metal Cutting.","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1906"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"35783","relation_version_is_last":true,"title":["Microscopic Kinematographs Applied to the Research of Metal Cutting."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:12:13.132755+00:00"}
