Kuzu, Ali Taner; Karagüzel, Umut; Erbay, Batıray; Bakkal, Mustafa (Bellwether Publishing, Ltd., 2021-07-27)This study presents an investigation on the effectiveness, automation characteristics, and mechanics of joints between different material types namely glass fiber reinforced plastics (GFRPs) and SS304 stainless steel using ... -
Effects of turn-milling conditions on chip formation and surface finish
Rahimzadeh Berenji, Kaveh; Karagüzel, Umut; Özlü, Emre; Budak, Erhan (Elsevier Science BV, 2019-04-24)Turn-milling operations performed on mill-turn machines offer significant advantages provided that appropriate conditions are used. Compared to conventional machining processes, kinematics and geometry of turn-milling are ... -
Experimental analysis on drilling of Al/Ti/CFRP hybrid composites
Kayihan, Mete; Karagüzel, Umut; Bakkal, Mustafa (Bellwether Publishing, 2020-09-17)Carbon fiber reinforced composites (CFRP) have superior mechanical properties such as high strength/density ratio, and good damping ability. CFRP which is frequently used in parts in the aviation industry can also be single ... -
Frezeyle tornalamada takımda ortaya çıkan termal deformasyonların modellenmesi
Karagüzel, Umut; Bakkal, Mustafa; Budak, Erhan (Gazi Universitesi Muhendislik-Mimarlik, 2017)Frezeyle tornalama işleminde işlemiş parça doğruluğu ve üretkenliği arttırarak işlem performansını iyileştirmek kesme kuvvetlerini ve takım ucundaki ısı kaynaklı deformasyonları kontrol etmekle mümkündür. Bu çalışmanın ... -
Investigating effects of milling conditions on cutting temperatures through analytical and experimental methods
Karagüzel, Umut; Budak, Erhan (Elsevier Science SA, 2018-12)Cutting temperatures in milling operations have a significant impact on tool wear, size and shape tolerances and residual stresses of the machined part. Prediction and measurement of cutting temperatures in milling, on the ... -
Mechanical and thermal modeling of orthogonal turn-milling operation
Karagüzel, Umut; Bakkal, Mustafa; Budak, Erhan (Elsevier Science BV, 2017)Turn-milling is a relatively new machining technology which is performed for cutting of symmetrical or non-symmetrical rotational parts. To improve productivity, determination of cutting parameters in turn-milling is ... -
A thermo-mechanical model of drill margin-borehole surface interface contact conditions in dry drilling of thick CFRP laminates
Karpat, Yiǧit; Karagüzel, Umut; Bahtiyar, Onur (Elsevier Ltd, 2020-04-23)Dry drilling of thick carbon fiber reinforced polymer (CFRP) laminates requires careful selection of process parameters in order to obtain acceptable borehole surface quality. Complex contact conditions between the drill ... -
Ti6Al4V Alaşımının talaşlı imalatı sırasında termal kamera ile sıcaklık ölçümü ve sonlu elemanlarla modellenmesi
Karagüzel, Umut (2019-06-26)Talaşlı imalat en yaygın kullanılan imalat yöntemlerinden biridir. Talaşlı imalatta en önemli problemlerin başında yüzey bütünlüğünü, parça toleransını ve takım ömrünü dolayısıyla maliyeti etkilemesi nedeniyle kesme sıcaklığı ... -
Transient multi-domain thermal modeling of interrupted cutting with coated tools
Karagüzel, Umut (Springer Science and Business Media Deutschland GmbH, 2021-09)Interrupted cutting operations, such as milling, produce fluctuating tool temperatures which directly affect the process outputs. Thus, prediction of cutting tool temperatures enables process planning, selection of materials ...
