Automated image processing for scratch detection on specular surfaces

Okbay, Volkan
In industry, problems due to human error, mechanical flaws and transportation may occur; besides, they need to be detected in fast and efficient ways. In order to eliminate failure of human inspection, automated systems come in action, usually image processing involved. This thesis work, targets one common mass production problem on specular surfaces, i.e. scratch detection. To achieve this, we have implemented two different prototypes. The low-cost system is based on basic line detection, and the mid-end system depends on learning based detection. Both systems are implemented on embedded platforms and performance comparisons are done. Detailed analysis is carried out on computational cost and detection performance. This real-world episode is done on a mechanical prototype in laboratory environment


Performance analysis of drilling fluid liquid lubricants
Sonmez, Ahmet; Kök, Mustafa Verşan; Ozel, Reha (Elsevier BV, 2013-08-01)
Excessive torque is one of the most important problems in oil/gas drilling industry. Friction between wellbore/casing and drill string causes excessive torque. This study discusses performance analysis of drilling fluid lubricants, which are used as friction reducers in well-bores. Three different types of chemical commercial lubricants, which are fatty acid and glyceride based, triglyceride and vegetable oil based and polypropylene glycol based, diesel oil, and crude oil, which consists of different API gr...
Shape optimization of an excavator boom by using genetic algorithm
Uzer, Cevdet Can; Söylemez, Eres; Department of Mechanical Engineering (2008)
This study concerns with the automated structural optimization of an excavator boom. The need for this work arises due to the fact that the preparation of the CAD model, performing finite element analysis and model data evaluation are time consuming processes and require experienced man power. The previously developed software OptiBOOM, which generates a CAD model using a finite set of parameters and then performs a finite element analysis by using a commercial program has been modified. The model parameter...
Vibration induced stress and accelerated life analyses of an aerospace structure
Özsoy, Serhan; Kadıoğlu, Fevzi Suat; Department of Mechanical Engineering (2006)
Fatigue failure of metallic structures operating under dynamic loading is a common occurrence in engineering applications. It is difficult to estimate the response of complicated systems analytically, due to structure̕s dynamic characteristics and varying loadings. Therefore, experimental, numerical or a combination of both methods are used for fatigue evaluations. Fatigue failure can occur on systems and platforms as well as components to be mounted on the platform. In this thesis, a helicopter̕s Missile W...
Assessment of sheet metal forming processes by numerical experiments
Önder, İ. Erkan; Tekkaya, A. Erman; Department of Mechanical Engineering (2005)
Sheet metal forming technologies are challenged especially by the improvements in the automotive industry in the last decades. To fulfill the customer expectations, safety requirements and market competitions, new production technologies have been implemented. This study focuses on the assessment of conventional and new sheet metal forming technologies by performing a systematic analysis. A geometry spectrum consisting of six different circular, elliptic, quad cross-sections are selected for the assessment ...
Computerized test procedure for industrial radiographic examination of metallic welded joints
Güneş, E. Evren; Doyum, Bülent; Department of Mechanical Engineering (2004)
Radiography is an extensively used NDT method, especially in nuclear, aerospace and automotive industries where optimal designs call for greater reliability. The rules corresponding to industrial radiography are defined in a system of radiographic standards. The standards related to the radiographic testing of metallic welded joints had been harmonised in all over the Europe and at the end in 1997, the standard "EN 1435" was established and published. Since then, this standard has become the most widely use...
