Tool point Frequency Response Function (FRF) for micro tools cannot be measured using impact testing and modal analysis. In addition, micro machining operations are performed at high spindle speeds and due to the gyroscopic moments and centrifugal forces tool point FRF changes during machining operations. In this study, micro tools are modeled analytically including the fluted geometry of the tool and operational effects. Moreover, for the machining centers where spindle geometry is unknown, a new coupling method is proposed which enables to couple experimentally obtained idle spindle dynamics with analytically calculated rotating holder-tool dynamics.

Investigating Dynamics of Machine Tool Spindles under Operational Conditions Özşahin, Orkun; Özgüven, Hasan Nevzat (2011-05-13) Chatter is one of the major problems in machining and can be avoided by stability diagrams which are generated using frequency response functions (FRF) at the tool tip. During cutting operations, discrepancies between the stability diagrams obtained by using FRFs measured at the idle state and the actual stability of the process are frequently observed. These deviations can be attributed to the changes of machine dynamics under cutting conditions. In this paper, the effects of the cutting process on the spi...
RECONSTRUCTION OF PERMITTIVITY AND CONDUCTIVITY PROFILES OF A DIELECTRIC SLAB IN THE TIME DOMAIN BY DESCENT METHODS ONDER, M; Kuzuoğlu, Mustafa (Institution of Engineering and Technology (IET), 1992-10-01) An optimisation approach is presented for the problem of reconstructing the permittivity and conductivity profiles of a dielectric slab from the reflected and transmitted field data. The problem is treated as an optimal control problem where the norm of the difference of measured and calculated boundary data is minimised subject to the state equation governing the system. The original constrained optimisation problem is reduced to the evaluation of stationary points of an augmented functional which is obtai...
Comparison of multi-objective and single-objective approaches in feasibility enhanced particle swarm optimization Hasanoglu, Mehmet Sinan; Dölen, Melik (Journal of the Faculty of Engineering and Architecture of Gazi University, 2020-01-01) In this study, solutions for multi-objective constrained problems and their fixed weight linearly aggregated single-objective variants were obtained using the Pareto based multi-objective feasibility enhanced particle swarm optimization and single-objective approaches respectively. Comparisons involving three problems (two of which were highly constrained) revealed that optimizations performed using the multi-objective approach resulted in solutions that were also suitable for all single-objective criteria....
Interaction of anodized Ti6A17Nb with simulated body fluid Izmir, Merve; Tufan, Yiğithan; Ercan, Batur (Journal of the Faculty of Engineering and Architecture of Gazi University, 2019-01-01) The present work investigates modification of Ti6Al7Nb alloy surfaces using anodization for orthopedic applications. By optimizing the anodization parameters. nanotubular oxide layers with tubular diameters tailored between 25 nm to 140 nm was fabricated on Ti6Al7Nb alloy surfaces. When Ti6Al7Nb samples possessing nanotubular surface features were immersed in simulated body fluid for 30 days. calcium phosphate mineral formation was observed on these surfaces. Results showed that anodized Ti6Al7Nb samples wi...
Generalized beam angle statistics for shape descrition Tola, Ömer Önder; Yarman Vural, Fatoş Tunay; Department of Computer Engineering (2004) In this thesis, we introduce a new shape descriptor and a graph based matching algorithm to detect a template shape in an image that contains a single object. The shape descriptor, Generalized Beam Angle Statistics, GBAS is obtained with the generalization of the boundary based shape descriptor, Beam Angle Statistics, BAS
