Self-excited vibrations, namely chatter, is one of the most important problems in machining operations. Under certain conditions, the cutting system becomes unstable as a result of the dynamic interaction between the process and the structures. As a result of this dynamic interaction between the cutting tool and the work material, a high level noise is generated in addition to the very poor machined part surface quality. Chatter models used for the generation of the stability diagrams need the frequency response function (FRF) at the tool work interface point in addition to the material constants. Although high level noise generated in chatter is undesirable in a production facility, it creates a unique opportunity for the chatter tests. The frequency spectrum can be used to identify the chatter and the source when combined with the modal data. Considering the practical difficulties of placing a sensor in the cutting zone, the importance of this very inexpensive and reliable way of chatter identification and measurement can be understood much better. In this paper, the experimental verification, by using noise measurements, of the stability diagrams obtained from recently developed chatter and structural dynamics models for milling will be demonstrated with example applications. The comparison between the modeled and measured FRFs, the correlation of the modal frequencies with the predicted and the measured chatter frequencies by using the noise measurements will also be presented.

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 frequency response function at the tool tip are known to predict stable cutting conditions. However, the forward solution may fail to perform accurately in cases wherein the aforementioned information is partially known or varies based on the process conditions, or could involve several uncertaint...
The position control of a spatial binary hyper redundant manipulator through its inverse kinematics Bayram, Atilla; Özgören, Mustafa Kemal (2013-01-01) This article is about the position control of a binary hyper redundant manipulator, which is driven by pneumatic on-off actuators. The end platform of the binary hyper redundant manipulator bears a small fine tuning manipulator, which is a continuously actuated six-joint manipulator attached as a versatile error-compensation tool. It is employed to compensate especially the discretization errors. The position control aims to make the end-effector of the fine tuning manipulator track a specified sequence of ...
The Design of a high frequency pulse width modulation integrated circuit with external synchronization capability Şahin, Osman Ulaş; Koçer, Fatih; Department of Electrical and Electronics Engineering (2017) The Pulse Width Modulation (PWM) has been playing an active role in circuits and systems for many years. The PWM is an irreplaceable part of the switch-mode power supplies (SMPS) and the class D power amplifiers (PA). The high frequency PWM operation is the key for having more compact SMPSs and class D PAs since it provides size reduction of the passive components, which dominates the size and the cost of these circuits. The digital implementation of the high frequency PWM inherently suffers from the lack o...
A novel algorithm for prediction off-line stator leakage inductance and on-line stator resistance of induction motors Sezgin, Volkan; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2009) In vector control of induction motors it is essential to know the parameters of the motor. Known approaches to this problem have some drawbacks. This thesis work is planned to develop solutions to the existing problems. The proposed solutions will be implemented and tested.
Chatter detection using vibrational and acoustic emissions in turning process Süleyman, Büyükkoçak; Kılıç, Şener; Özer, Mehmet Bülent; Ünver, Hakkı Özgür (null; 2013-09-20) Chatter vibration is a longstanding problem for machining industry. It lowers both surface finish quality and life of cutting tool. In this study, real time chatter vibration detection system is designed and tested experimentally. A traditional lathe, equipped with two accelerometers placed on cutting tool in two orthogonal coordinates and a microphone, is used for machining a steel rod in face turning operation. During cutting process analog data of accelerometers and microphone is acquired by data acquisi...
