Milling force estimation based on harmonic force model and acceleration feedback İlme, Mert; Çalışkan, Hakan; Özşahin, Orkun (2025-01-01) Monitoring milling forces is crucial as they directly reflect the milling process. Direct force measurement using a dynamometer is challenging for industrial applications. However, indirect force measurement can be achieve...
Optimization of variable pitch milling tools for improved chatter stability Özşahin, Orkun (2024-06-30) Chatter is an important problem in machining operations which causes poor surface quality, increased tool wear, failure of cutting tool and even machine tool, and excessive noise during machining hence reduced productivity...
Development of a dynamic simulation model for CNC table vibration estimation in milling operations Frezeleme işleminde CNC tabla titreşimlerinin kestirimi için dinamik simülasyon modeli geliştirilmesi Altun, Barış; Çalışkan, Hakan; Özşahin, Orkun (2024-01-01) Recent developments under Industry 4.0 allows to collect and analyze measurements during milling process. For such projects to be done, software needs to be developed. Developing software through testing is expensive and t...
RECURSIVE DEFINING OF FORCE COEFFICIENTS IN MILLING PROCESS WITH ACCELEROMETER Altun, Barış; Çalışkan, Hakan; Özşahin, Orkun (2022-09-02)
Alternative experimental methods for machine tool dynamics identification: A review Iglesias, Alexander; Taner Tunç, L.; Özşahin, Orkun; Franco, Oier; Munoa, Jokin; Budak, Erhan (2022-05-01) © 2022An accurate machine dynamic characterization is essential to properly describe the dynamic response of the machine or predict its cutting stability. However, it has been demonstrated that current conventional dynamic...
Effect of spindle design on spindle dynamics and chatter stability Özşahin, Orkun; Budak, Erhan; Rahimzadeh Berenji, Kaveh (2021-07-23)
Design optimization of tool holder extension for enhanced chatter stability by using component mode tuning method Karataş, G.; Özşahin, Orkun; Özgüven, Hasan Nevzat; Budak, E. (2020-01-01) © 2020 The Authors. Published by Elsevier B.V.Tool overhang length tuning by matching the modes of the tool-holder extension-holder-spindle (TEHS) assembly components creating dynamic absorber effect is one of the rare cha...
Identification of spindle dynamics by receptance coupling for non-contact excitation system Özşahin, Orkun; Budak, Erhan; Rabréau, Clément; Le Loch, Sébastien (Elsevier BV; 2019-01-01) The identification of spindle dynamics plays a crucial role in accurate prediction of the stability diagrams for high speed machining operations. In this study, variations of the mode shapes of the tool-spindle assembly at...
ANALYSIS AND DESIGN OF VARIABLE PITCH TOOLS FOR THE IMPROVED PRODUCTIVITY Özşahin, Orkun (null; 2018-10-10)
Use of inverse stability solutions for identification of uncertainties in the dynamics of machining processes Tunc, Lutfi Taner; Özşahin, Orkun (Springer Science and Business Media LLC, 2018-09-01) Research on dynamics and stability of machining operations has attracted considerable attention. Currently, most studies focus on the forward solution of dynamics and stability in which material properties and the frequenc...
