Integrated framework for in-process modal analysis and tool–workpiece engagement detection Kaçan, Samet Can; Çalışkan, Hakan (2026-02-01) This paper presents an Extended Kalman Filter (EKF)-based real-time methodology for in-process modal identification and tool–workpiece engagement detection in milling operations. Unlike conventional offline Experimental Mo...
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...
A Complete Mathematical Modelling of Milling Spindle and Motor for Force Estimation Studies Batuhan, Altınel; Cumhur, Özbaş; Çalışkan, Hakan (2024-11-03)
A PRELIMINARY STUDY OF BALL BURNISHING PROCESS ON GROUND SURFACES Dölen, Melik; Yaman, Ulaş; Çalışkan, Hakan; Özşahin, Orkun (2024-11-01) This study investigates the performance of the ball-burnishing process on defective surfaces – a subject that has received limited attention in the existing literature. Surface defects and irregularities can arise from var...
Real-Time Milling Chatter Detection and Control with Axis Encoder Feedback and Spindle Speed Manipulation Çalışkan, Hakan (2024-08-01) This paper introduces a complete real-time algorithm, where the chatter is detected and eliminated by spindle speed manipulation via the chatter energy feedback calculated from the axis encoder measurement. The proposed me...
Milling Force Estimation Using Angular Domain Harmonics with Cutting and Edge Coefficients Mert, İlme; Çalışkan, Hakan (2024-07-17)
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...
Elektro-Hidrostatik Eyleyicilerde Dinamik Direngenliğin İyileştirilmesi Özbaş, Cumhur; Afatsun, Ahmet Can; Çalışkan, Hakan (2023-09-15) Electro-hydrostatic actuators are preferred in the aviation industry due to their compact design and high energy efficiency. Unlike conventional hydraulic actuator systems, electro-hydrostatic actuators are controlle...
