The Metrology and Imaging modes of the acoustic reflection microscope are applied to spherically shaped specimens. Metrology is usually practiced by translating the specimen along the acoustic beam axis. This operation yields a measurement of the local Rayleigh velocity at a single location in the specimen plane. Imaging is accomplished through raster-scanning in the plane transverse to the bea...

Bu çalışmada, AISI 52100 çeliğinin geleneksel ve ultrasonik tornalanmasında işlem parametrelerinin performans karakteristikleri üzerindeki etkileri yani işlenebilirliği deneysel, sayısal istatistiksel olarak araştırıldı. Çalışmada, işlenebilirliğin tespit edilmesi amacıyla, bağımsız değişkenlerin takım ömrü üzerine olan belirlendi. Deneysel çalışmalar, 50, 100 150 m/dak kesme hızları, 0.1 mm/de...

Abstract Locally adapted properties within a machine component offer opportunities to increase the performance of by using high strenght materials where they are needed. The economic production such hybrid components on other hand represents major challenge. new tailored forming process chain, which is developed collaborative research center (CRC 1153) possible solution produce components. This...

This paper presents experimental results of wear process under dry and boundary lubricated metallic (AISI 1034/AISI 52100) contacting bodies with different surfaces morphologies subjected to a wide range of kinematic fretting conditions. Analysis of damage mode observed under such fretting conditions is elucidated in context of surfaces morphologies therefore associated with surface manufacturi...

The experimental investigations of the tool wear in turning of EN 31 alloy steel at different cutting parameters are reported in this paper. Mathematical model has been developed for flank wear using response surface methodology. This mathematical model correlates independent cutting parameters viz. cutting speed, feed rate and depth of cut with dependent parameters of flank wear. This model is...

At present, with the adjustment of the structure of the steel industry, the steel logistics industry is also engaged in integrating. Steel logistics resource integration is an important problem to be solved. Based on previous research on steel logistics resource integration, this paper proposes a new research perspective on steel logistics resources integration: supply-demand network of steel l...
