Such a discontinuous chip flows up in roll-in motion toward the tool face A slip line field of the discontinuous chip is obtained by means of visioplasticity and a hodograph is drawn using the slip line and the distribution of velocity on plastic region. The possibility of the formation is discussed through properties of the slip line and the hodograph. As a result of the examination using E.P. Green’s and W. Prager’s methods, it was known that the rate of plastic work was positive. In this paper, the difference in mechanism between this type and other types of discontinuous chip formation is shown in comparison with their slip line field and hodograph.","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"31785","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Takeaki, KITAGAWA"}]}]},"item_2_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"北見工業大学"}]},"item_2_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"北川, 武揚"}],"nameIdentifiers":[{"nameIdentifier":"31784","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":"2016-11-22"}],"displaytype":"detail","filename":"2-2-12.pdf","filesize":[{"value":"6.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2-2-12.pdf","url":"https://kitami-it.repo.nii.ac.jp/record/6211/files/2-2-12.pdf"},"version_id":"35b5f345-d58e-469a-8795-3b09267871fc"}]},"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":"せん断型切くず生成機構の二，三の例*","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"せん断型切くず生成機構の二，三の例*"}]},"item_type_id":"2","owner":"1","path":["22"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-04-09"},"publish_date":"2007-04-09","publish_status":"0","recid":"6211","relation_version_is_last":true,"title":["せん断型切くず生成機構の二，三の例*"],"weko_creator_id":"1","weko_shared_id":3},"updated":"2022-12-13T02:19:33.604630+00:00"}
