In this thesis study, a prototype is designed in order to improve the weighing accuracy of the weighing and packaging machine that used in sugar factories. The unavoidable factory conditions cause weighing and packaging machine to do weighing errors. In order to correct these errors, the prototype produced in this study was designed as a quality control unit which will take the excess sugar and fill the deficient sugar in the sacks. Because of being small and having an easy installation, the application of the prototype was done considering 1-kilogram bags rather than available 50-kilogram ones. So as to correct the faulty weighing, sugar extraction and filling processes are provided from a bunker which is designed on the basis of data obtained by statistical analysis. For suction, vacuum is used and filling is realized by a ball valve. Upwards and downwards movement of the bunker is carried out with a pneumatic cylinder. Weighing information is received via a load cell and an indicator. Control of all these devices is provided by PLC hardware and SCADA interface.

Development of a two-fingered and a four-fingered robotic gripper Doğan, Burak; Soylu, Reşit; Department of Mechanical Engineering (2010) In this thesis study, a two-fingered gripper and a four-fingered multipurpose gripper are developed and manufactured. In addition to development of robotic hands, computer control hardware and software are also developed for computer control of both hands. The two-fingered gripper is designed for a specially defined pick and place operation. Its task is to pick a cylindrical work piece and place it in the appropriate position in a flexible manufacturing cell. Pneumatic actuator is used for power generation ...
Development of test structures and methods for characterization of MEMS materials Yıldırım, Ender; Arıkan, Mehmet Ali Sahir; Department of Mechanical Engineering (2005) This study concerns with the testing methods for mechanical characterization at micron scale. The need for the study arises from the fact that the mechanical properties of materials at micron scale differ compared to their bulk counterparts, depending on the microfabrication method involved. Various test structures are designed according to the criteria specified in this thesis, and tested for this purpose in micron scale. Static and fatigue properties of the materials are aimed to be extracted through the ...
Conceptual design and analysis of an industrial type vacuum sweeper Aygün, Buket; Albayrak, Kahraman; Department of Mechanical Engineering (2009) In this thesis, design and development and manufacturing processes of an industrial type vacuum sweeper is presented. Thesis is financially supported by Ministry of Industry and Trade-Turkey and Müsan A.Ş. (Makina Üretim Sanayi ve Ticaret A.Ş.) under SAN-TEZ project number 00028.STZ.2007-1. It is aimed to make innovative design changes and developments on the Müsan VSM 060 type vacuum sweeper. To achieve this aim, alternative configuration designs are prepared by using commercial 3D modeling program, Catia™...
Development of postprocessor, simulation and verification software for a five-axis CNC milling machine Cengiz, Ender; Gökler, Mustafa İlhan; Department of Mechanical Engineering (2005) Five-axis CNC milling machine tools bring great facility to produce complex workpieces with increased dimensional accuracy and better surface quality in shorter machining times. However, kinematics of five-axis machine tools has a complex form which makes it difficult to operate these machine tools properly. The difficulty arises from the complexity of NC-Code generation and tool path verification. Collision of machine tool or setup components with each other is a severe problem in five-axis machining opera...
Exact solution of rotating FGM shaft problem in the elastoplastic state of stress Akis, Tolga; Eraslan, Ahmet Nedim (Springer Science and Business Media LLC, 2007-10-01) Plane strain analytical solutions to estimate purely elastic, partially plastic and fully plastic deformation behavior of rotating functionally graded (FGM) hollow shafts are presented. The modulus of elasticity of the shaft material is assumed to vary nonlinearly in the radial direction. Tresca's yield criterion and its associated flow rule are used to formulate three different plastic regions for an ideal plastic material. By considerina different material compositions as well as a wide range of bore radi...
