Evaluation of the effects of drilling parameters, tool geometry and core material thickness on thrust force and delamination in the drilling of sandwich composites
Ekici, Ergün; Uzun, Gültekin; Altaş, Sedat (World Scientific Publishing, 2021)This study examined the effects of drilling parameters, tool geometry, and core material thickness (CMT) on thrust force and the delamination factor in the drilling of sandwich composites. Aluminum honeycomb (10 and 15mm ... -
An Experimental Study on Hole Quality and Different Delamination Approaches in the Drilling of CARALL, a New FML Composite
Ekici, Ergün; Motorcu, Ali Rıza; Yıldırım, Ensar (Belgrade University, 2021)In this study, the hole quality was investigated in the drilling of CARALL composite. In addition, the delamination factor calculation approaches of Chen, Davim, and Machado were compared in terms of the delamination damage ... -
Multi-Objective Optimization of Process Parameters for Drilling Fiber- Metal Laminate Using a Hybrid GRA-PCA Approach
Ekici, Ergün; Motorcu, Ali Rıza; Uzun, Gültekin (Belgrade University, 2021)This study investigated the effects of drilling parameters and cutting tool coating conditions on the thrust force, surface roughness, and delamination factor in the drilling of fiber-reinforced carbon reinforced aluminum ... -
Performance of Multilayer Coated and Cryo-Treated Uncoated Tools in Machining of AISI H13 Tool Steel—Part 1: Tungsten Carbide End Mills
Çiçek, Adem; Kıvak, Turgay; Ekici, Ergün; Kara, Fuat; Uçak, Necati (Springer, 2021)This paper focused on the performance of tungsten carbide end mills in machining of AISI H13 hot work tool steel under dry and wet conditions. The tool performance was evaluated in terms of resultant cutting force (Fc), ... -
Performance of Multilayer Coated and Cryo-treated Uncoated Tools in Machining of AISI H13 Tool Steel—Part 2: HSS End Mills
Çiçek, Adem; Ekici, Ergün; Kıvak, Turgay; Kara, Fuat; Uçak, Necati (Springer, 2021)This part of the study aimed to investigate the effects of cryogenic treatment applied to uncoated high speed steel (HSS) end mills on cutting forces (Fc), surface roughness (Ra), and tool life. The milling tests were ...
