In this thesis, a generic energy consumption model is developed for turn-mill systems which could be adopted for all turn-mill machine tools. Also energy characterization studies is performed to a turn-mill machine tool in order to validate the presented model and a methodology is created to develop a feature based energy consumption model for this turn-mill system considering cutting parameters during cutting operations of 304 stainless steel. This model predicts the energy consumption of the turn-mill machine tool during machining operation based on used features and cutting parameters with an accuracy of 95%. The results of this research work showed that depth of cut is the most significant factor on power consumption during machining processes. Furthermore, the present work outlines an experimental study to investigate the energy consumption of orthogonal turn-milling processes performed on a turn-mill machine tool. Effect of cutting parameters on power requirement and energy consumption of turn-milling processes are analyzed. In addition, conventional turning processes are performed in the same cutting conditions in order to compare their power and energy consumption with orthogonal turn-milling processes. It is concluded that in spite of high power requirement of the turn-milling processes, these processes result in higher material removal rates and are more energy efficient.

Energy consumption characteristics of turn-mill machining Moradnazhad, Mariyeh; ÜNVER, HAKKI ÖZGÜR (2017-07-01) Reducing the energy consumption of manufacturing processes and machine tools can considerably affect the environmental and economic impact of industrial activities. Since the 2008 global financial crisis, many scholars have focused on modeling the energy consumption of basic machining processes such as turning, milling or grinding, etc., and investigated the consumption characteristics of related machine tools. At the same time, various industries have increased their use of more complex and hybrid machine ...
Composite index for benchmarking local energy systems of Mediterranean port cities Kılkış, Şiir (2015-12-01) Benchmarking the performance of local energy systems requires an integrated approach. This paper develops a composite index that consists of a unique set of 7 dimensions and 35 main indicators. The SDEWES (Sustainable Development of Energy, Water, and Environment Systems) Index is applied to a sample of 22 Mediterranean port cities. The index integrates energy and CO2 emissions data from SEAP (Sustainable Energy Action Plans). The values of the indicators are aggregated based on the Min-Max method for a fin...
Analytical model for superconducting generators for wave energy systems Bernholz, Jan; Keysan, Ozan; Mueller, MA (2016-08-20) The objective of the research is to obtain a better understanding of the feasibility of superconducting machine concepts for wave energy systems. These topologies were previously investigated by Keysan with regards to wind energy. An optimization design tool is developed in Matlab for the electrical design of the machine types. Two case studies, namely the Archimedes Wave Swing and the Oyster wave energy converter for the double-claw pole design are applied and presented in this work. The main advantage of ...
Energy Modeling of Wearable Intelligent Batteryless Health Monitoring System with Thermal-Vibrational Hybrid Harvester Sharone, Molly; Muhtaroğlu, Ali; Sustainable Environment and Energy Systems (2021-9-18) A unified model is developed in this thesis with a thermal-vibrational hybrid energy harvester and a wearable intelligent batteryless health monitoring system for accurate prediction of energy flow from generation to consumption. Analytical models are developed first based on environmental conditions, energy conversion parameters, geometry, and datasheet specifications. Data from literature is utilized from multiple energy harvesters, interface electronics, the intelligent sensor nodes and monitored patient...
Energy Harvesting Through Lumped Elements Located on Metamaterial Absorber Particles Gunduz, Ozan T.; Sabah, Cumali (2015-09-09) We propose and examine an enhanced version of a multi-band metamaterial absorber for an energy harvesting application. The numerical results of the multi-band absorption characteristics of no-load conditions are presented and compared with the loading conditions. At most % 50 of the incoming wave energy whose correspondence is 0.25 Watt is converted to real power at the resistive loads at 5.88 GHz by the usage of 2000 ohms loads. In order to evaluate the harvesting efficiency, three different types of effic...
