    Assessment of Transition from Mechanical Engineering to Mechatronics Engineering in Turkey
    (Tempus Publications, 2009) Yavuz, Hakan; Mistikoglu, Selcuk
    This paper gives an assessment of the transition from the mechanical engineering curriculum to the mechatronics engineering curriculum in Turkey. It looks at the requirements for the transition and analyses the approaches adopted by Turkish universities. To achieve this, the study provides a review of the mechanical engineering departments and the proportion of mechatronics courses tonight within these departments. As presented in the paper, some universities prefer a separate department for mechatronics engineering; others introduce optional courses, while the rest replace some core modules with mechatronics engineering type courses. Therefore, this work classifies the universities into three groups. In addition to Turkish universities, some selected cases of universities from Asia, the USA, Canada, and Europe are also included as examples of each identified approach, thereby providing the necessary background for comparison. The comparative study reveals that there does lot seem to be a definitive approach to updating a mechanical engineering curriculum or a mechatronics engineering curriculum with any clearly do lined structure. Nevertheless, the proportions of mechatronics courses in mechanical engineering curricula in Turkish universities indicate that the required measures seem to have been taken in most of the cases. In this study an attempt was also made to identify the problems that Turkish universities are facing in mechanical engineering education and some suggestions were made to overcome these difficulties to improve the quality of such education in Turkey. The paper concludes with a general suggestion that consists of a set of solution models that may allow a smooth transition from a mechanical engineering to mechatronics engineering curriculum.

    Design and Development of a Cartesian Robot for Multi-disciplinary Engineering Education
    (Tempus Publications, 2010) Mistikoglu, Selcuk; Ozyalcin, Ibrahim
    This paper presents a teaching approach based on hands-on learning. The details of the approach presented here cover the theoretical aspects and the practical implementation of the engineering study. The study provides details of a model for a multi-disciplinary engineering education approach that provides the students with fundamental theoretical and practical knowledge. Furthermore, the results of the study reveal that the method is in compliance with the Accreditation Board for Engineering and Technology (ABET) criteria for education in engineering. Moreover, the benefits of the approach and the related results, which indicate that graduating students do benefit from the education provided, are also presented.

    An Enhanced Control Technique for the Elimination of Residual Vibrations in Flexible-Joint Manipulators
    (Assoc Mechanical Engineers Technicians Slovenia, 2014) Conker, Caglar; Kilic, Ali; Mistikoglu, Selcuk; Kapucu, Sadettin; Yavuz, Hakan
    One method used to reduce or eliminate residual vibrations is to modify the input signal by using previously determined system parameters. In order to eliminate the residual vibration completely, these system parameters must be very accurately determined. In real systems, achieving such accuracy may not always be possible. To address this problem and to provide a solution, a new residual vibration elimination method is introduced in this study, which has proven to be useful especially in cases of uncertain parameters of estimated or predicted systems. It is shown that the technique is capable of handling high levels of uncertainty and is able to successfully eliminate or reduce residual vibrations in flexible systems. In this approach, the desired position of the system is primarily divided into two equal parts, and the generated input signal is used to eliminate vibration. This study presents theoretical and experimental results of the techniques applied to a flexible mechanical system; a comparative study of robustness performance is also provided. Simulation and experimental results show that the oscillations are considerably decreased with a high degree of robustness in the presence of uncertainty regarding system parameters.

    Hybrid input shaping to suppress residual vibration of flexible systems
    (Sage Publications Ltd, 2012) Yavuz, Hakan; Mistikoglu, Selcuk; Kapucu, Sadettin
    This paper presents hybrid input shaping method to eliminate residual vibration of multi-mode flexible systems. This method, initially designed for one degree of systems, is modified to apply on linear and nonlinear multi-mode systems. In this method, firstly the flexible system is uncoupled using modal analysis method, and then the parameters of the decoupled system are used to shape the command template signal. A ramp plus ramped cycloid plus ramped versine is proposed as the command template signal to be preshaped. The template function is preshaped to yield zero residual vibration for point to point motion and then the resulting trajectory is convolved with a sequence of two impulses to obtain a twice shaped input. The proposed method is applied to eliminate residual vibration of a linear multimass and flexible joint manipulator types of systems. Simulation results show that the oscillations are considerably decreased with a high degree of robustness in the presence of system parameters uncertainty.

    Recent Developments in Friction Stir Welding of Al-alloys
    (Springer, 2014) Cam, Gurel; Mistikoglu, Selcuk
    The diversity and never-ending desire for a better life standard result in a continuous development of the existing manufacturing technologies. In line with these developments in the existing production technologies the demand for more complex products increases, which also stimulates new approaches in production routes of such products, e.g., novel welding procedures. For instance, the friction stir welding (FSW) technology, developed for joining difficult-to-weld Al-alloys, has been implemented by industry in manufacturing of several products. There are also numerous attempts to apply this method to other materials beyond Al-alloys. However, the process has not yet been implemented by industry for joining these materials with the exception of some limited applications. The microstructures and mechanical properties of friction stir welded Al-alloys existing in the open literature will be discussed in detail in this review. The correlations between weld parameters used during FSW and the microstructures evolved in the weld region and thus mechanical properties of the joints produced will be highlighted. However, the modeling studies, material flow, texture formation and developments in tool design are out of the scope of this work as well as the other variants of this technology, such as friction stir spot welding (FSSW).
