In the present work, single-point diamond turning experiments on single-crystal germanium （100）, （110） and（111） planes were conducted in order to examine their ultraprecision machining characteristics. Three kinds of surface textures and chip morphologies were observed during the brittle-ductile transition of the machining mode. The brittle-ductile boundary changed significantly with the crystal orientations of the workpieces. Due to the crystallographic anisotropy, micro-fractures were generated on the workpiece surface in a radial pattern from the rotation center. However, it was possible to produce completely ductile-cut surfaces on all crystal orientations by using undeformed chip thicknesses smaller than a critical value, namely, the minimum critical undeformed chip thickness, which was approximately 60 nm under the present conditions. Compared to wet cutting, dry cutting was beneficial for ductile machining on a few specific crystal orientations. The findings in this study provide criterions for determining process parameters for the fabrication of aspherical and diffraction infrared optics using single-crystal germanium.", "subitem_description_type": "Abstract"}]}, "item_3_description_194": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_description": "application/pdf", "subitem_description_type": "Other"}]}, "item_3_full_name_183": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "36417", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "田牧, 純一", "nameLang": "ja"}]}, {"nameIdentifiers": [{"nameIdentifier": "44823", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "40178025", "nameIdentifierScheme": "KAKEN", "nameIdentifierURI": "https://nrid.nii.ac.jp/ja/nrid/1000040178025 "}], "names": [{"name": "久保, 明彦", "nameLang": "ja"}]}]}, "item_3_publisher_212": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本機械学会"}]}, "item_3_relation_191": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.1299/jsmec.47.29", "subitem_relation_type_select": "DOI"}}]}, "item_3_rights_192": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Japan Society of Mechanical Engieneers, J.
