Micro-milling applications require high precision and dimensional accuracy. Chatter vibrations arising from unstable cutting conditions cause poor surface finish and damage to the cutting tools. Tool point frequency response functions (FRF); needed to generate stability diagrams, cannot be determined experimentally due to very small tool size. In this study an analytical model for tool point FRF of micro end mills is presented. An inverse algorithm is proposed to correct geometric representation and damping of the tool. The model and the correction methodology presented improve productivity and part quality in micro-milling through accurate prediction of chatter stability limits, enabling better cutting parameter selection.

Analytical modeling of the machine tool spindle dynamics under operational conditions Özşahin, Orkun; Özgüven, Hasan Nevzat (null; 2012-07-27) Chatter is an important problem in machining operations, and can be avoided by utilizing stability diagrams which are generated using frequency response functions (FRF) at the tool tip. In general, tool point FRF is obtained experimentally or analytically for the idle state of the machine. However, during high speed cutting operations, gyroscopic effects and changes of contact stiffness and damping at the interfaces as well as the changes in the bearing properties may lead to variations in the tool point FR...
Selection of design and operational parameters in spindle-holder-tool assemblies for maximum chatter stability by using a new analytical model Erturk, A.; Budak, E.; Özgüven, Hasan Nevzat (2007-07-01) In this paper, using the analytical model developed by the authors, the effects of certain system design and operational parameters on the tool point FRF, thus on the chatter stability are studied. Important conclusions are derived regarding the selection of the system parameters at the stage of machine tool design and during a practical application in order to increase chatter stability. It is demonstrated that the stability diagram for an application can be modified in a predictable manner in order to max...
Learning Deep Temporal Representations for fMRI Brain Decoding Firat, Orhan; Aksan, Emre; Oztekin, Ilke; Yarman Vural, Fatoş Tunay (2015-07-11) Functional magnetic resonance imaging (fMRI) produces low number of samples in high dimensional vector spaces which is hardly adequate for brain decoding tasks. In this study, we propose a combination of autoencoding and temporal convolutional neural network architecture which aims to reduce the feature dimensionality along with improved classification performance. The proposed network learns temporal representations of voxel intensities at each layer of the network by leveraging unlabeled fMRI data with re...
Numerical and experimental analysis of indentation Koray, Erge; Tekkaya, Erman; Department of Mechanical Engineering (2005) Indentation tests are widely used with simultaneous measurements of indentation depth and force especially for determining material properties. In this study; numerical and experimental investigation of the force-indentation measurements is presented. For indentation tests on anisotropic metals, a novel indenter which is not self similar is used with three transducers to measure the displacements. It is seen that in order to have high repeatability and accuracy at the tests, workpiece and indenter parameter...
Numerical study on effects of computational domain length on flow field in standing wave thermoacoustic couple MERGEN, SÜHAN; Yıldırım, Ender; TÜRKOĞLU, HAŞMET (Elsevier BV, 2019-03-01) For the analysis of thermoacoustic (TA) devices, computational methods are commonly used. In the computational studies found in the literature, the flow domain has been modelled differently by different researchers. A common approach in modelling the flow domain is to truncate the computational domain around the stack, instead of modelling the whole resonator to save computational time. However, where to truncate the domain is not clear. In this study, we have investigated how the simulation results are aff...
