Tool wear evaluation by vibration analysis during end milling of AISI D3 cold work tool steel with 35 HRC hardness
(Elsevier Sci Ltd, 2007)In this study, the relationship between vibration and tool wear was investigated during end milling. For this purpose, a series of experiment were conducted in a vertical milling machine. An indexable CBN insert and AISI ... -
Experimental modelling and simulation with adaptive control of power plant
(Pergamon-Elsevier Science Ltd, 2007)This study presents a typical industrial plant whose performance is severely affected by disturbances, particularly by changes in the operating point. This is typically the case for power plants, which can be treated as ... -
Analysis of free and forced vibration of a cracked cantilever beam
(Elsevier Sci Ltd, 2007)Structures are weakened by cracks. When the crack size increases in course of time, the structure becomes weaker than its previous condition. Finally, the structure may breakdown due to a minute crack. Therefore, crack ... -
Synthesis and Characterization of bis(N,N-Diethylnicotinamide) p-Halogenobenzoate Complexes of Co(II)
(Asian Journal Of Chemistry, 2007)Halogenobenzoates are commonly applied in industrial and medical fields. Four novel mixed ligand complexes of Co(II) with p-florobenzoate, p-chlorobenzoate, p-bromobenzoate, p-iodobenzoate and N,N-diethylnicotinamide were ... -
Experimental and finite element study of the thermal conductivity of alpha-SiAlON ceramics
(Wiley, 2007)The thermal conductivity of monolithic Y-Sm/alpha-SiAlON was evaluated using experimental data and finite element analysis. The thermal diffusivities of Y, Y-Dy, and Y-Ce/alpha-SiAlON ceramics were also investigated ... -
Forecasting based on sectoral energy consumption of GHGs in Turkey and mitigation policies
(Elsevier Sci Ltd, 2007)Recently, global warming and its effects have become one of the most important themes in the world. Under the Kyoto Protocol, the EU has agreed to an 8% reduction in its greenhouse gas (GHG) emissions by 2008-2012. The GHG ... -
Vibration monitoring for defect diagnosis of rolling element bearings as a predictive maintenance tool: Comprehensive case studies
(Elsevier Sci Ltd, 2006)Vibration monitoring and analysis in rotating machineries offer very important information about anamolies formed internal structure of the machinery. The information gained by vibration analysis enable to plan a maintenance ... -
Brush seal temperature distribution analysis
(Asme, 2006)Brush seals are designed to survive transient rotor rubs. Inherent brush seal flexibility reduces frictional heat generation. However high surface speeds combined with thin rotor sections may result in local hot spots. ... -
Investigating the potential use of natural ventilation in new building designs in Turkey
(Elsevier Science Sa, 2006)The most economic air conditioning of living and working places can be achieved by natural ventilation if sufficient. This provides not only the circulation of clear air, but also the decrease of indoor temperature, ... -
Predictions of temperature distributions on layered metal plates using artificial neural networks
(Pergamon-Elsevier Science Ltd, 2006)The temperature distribution influences the amount of energy needed to heat a body. The benefits of using multi-layered metal plates (NIMP) are due to the requirement of a regular temperature distribution on the opposite ... -
Effect of cutting speed on the performance of Al2O3 based ceramic tools in turning nodular cast iron
(Elsevier Sci Ltd, 2006)This paper presents the results of an experimental investigation on the effect of cutting speed in turning nodular cast iron with alumina (Al2O3) based ceramic tools. Three different alumina based ceramic cutting tools ... -
