STRUCTURAL MATERIALS, METAL SCIENCE Graschenkov D. V., Schetanov B. V., Yefimochkin I. Yu., Shavnev A. A., Fedotov S. V. — Composite materials for heat-removing elements of power electronics An analysis of copper-based metal-matrix composite materials used in manufacturing of heat-removing bases for power electronics is carried out. Different compositions and types of filling materials (fibres, fractions) are considered, major methods of obtainment of these materials and their basic heat-transfer properties are adduced. TECHNOLOGIES AND EQUIPMENT FOR MACHINING, PHYSICOTECHNICAL PROCESSING, NON-CUTTING SHAPING Lazarev D. Ye., Nasad T. G. — Upgrading surface finish quality at bore operations of deep bores In this paper the method of vortex boring of precise holes was analyzed. There is periodically cutting during the processing of holes, similar to milling. The advantage of this method is the separation of chip into separate fragments, the formation of elemental chip. Also, the advantage of the vortex cutting is providing a high quality surface and high dimensional accuracy, low surface defects and low cutting tool deviation. Yenek M. — Investigation of tribological properties of the 30ХГСA steel elements machined by the tool clad on the base of multicomponent metal nitride The article presents results of studies of the wear process sample from hardened steel after machining cutting tool with carbide plates coated with metal nitride-based evaluation of surface roughness and tribological properties. TOOLING PRODUCTION Gourevich Yu. G., Ovcyannikov V. Ye., Frolov V. A. — A ferrite-pearlite grey cast iron burnisher with working surface alloyed by molybdenum The technology of the superficial alloyage by molybdenum of ferrito-perlitny gray cast iron pieces be means of the oxidation of its matrix by molybdenum oxide with the subsequent quenching has been developed. Hardness after quenching is commensurable with hardness after quenching of malleable cast iron. Expediency of use of the strengthened samples is proved when manufacturing instruments for roughting for processing of color alloys. Tabakov V. P., Saguitov D.

MACHINING-AND-ASSEMBLY PRODUCTION Rozinov A. Ya., Beskrovny A. Yu. — Design-engineering improvement of assembly facilities with electromagnetic fastening intended for carrying out field connections of hull plating Equations for calculation of holding power change of tractive flat-armature electromagnets and for magnetic induction determination in the air gap are given. Design-engineering features of round and rectangular electromagnets are considered. WELDING, RELATED PROCESSES AND TECHNOLOGY Belalov I. R., Feofanov A. N. — Use of process equipment with parallel kinematics Process equipment designed on basis of mechanisms with parallel kinematics is covered. Types of existing equipment, its merits and demerits are described. SPECIAL TECHNOLOGIES Andryushkin A. Yu. — Monodisperse liquid atomization by the supersonic gas-dynamic method The organized analysis of the constructive schemes holey revolving device of the crushing (HRDC) and mode of the spraying by means of HRDC. The presented results of the calculation and experimental dependency data of the diameter of the drop not viscous and viscous liquid from angular velocity of the rotation HRDC. The efficient supersonic gas dynamic method is offered for crushing the viscous liquids. Using the supersonic flow of the gas allows vastly to lower the sizes of the drop, but in combination with HRDC, get alike dripped. Bagaiskov Yu. S. — Composition development of a composite material of tubular filters for process liquid treatment Filtering features of different process liquids, filter requirements are studied. A filtration facility is considered in which tubular ceramics-based filters are used. Dependences of filter materials’ permeability and durability indices on filter fineness, type and content of binding agent are analyzed. TESTING AND DIAGNOSTICS METHODS IN ENGINEERING INDUSTRY Yanguirov I. F. — Mathematical model of an electromagnetic quality analyzer of metal pipes’ manufacture A mathematical model of the electromagnetic analyzer manufacturing quality metal pipes. We propose a mathematical model’s structures and electromagnetic analyzer manufacturing quality steel pipe, which has a high selectivity and resolution to technological defects of controlled items (eg oil and gas pipelines, welds, etc.). PROCESSES AND PRODUCTION AUTOMATION AND CONTROL, CAD SYSTEMS Kolosov S. P., Seleznev M. Ye. — Application of data intelligent analysis technique as a function of decision support system for glass-pipes calibration automated lines in production In publishers presents methods for automatic technical process, from functions caliber of glass-pipe, from workers of methods intellect analytics data, as monitoring bags. MATHEMATICAL MODELLING, CALCULUS OF APPROXIMATIONS AND SOFTWARE SYSTEMS Lomayev V. I., Sagatelyan G. R. — Computer simulation of the parabolic reflector finishing operation The article describes working surface finish of a radio antenna parabolic reflector made of a composite material. This operation is carried out on a specialized machine tool by using the method of fixed axes. A special computer program was developed: it allows to calculate the expected real shape of the processed surface depending on a variation of factors of the finishing process. The article suggests a classification of estimated deviations of the processed surface from sphericity. The required accuracy of the surface shape of a paraboloid of revolution is reached by neutralization of initial deviations which arise at forming of a reflector during the finishing process. STANDARDIZATION AND PRODUCT QUALITY CONTROL Zmiyevsky V. I. — Assessment of the quality management system of granular and powder metallurgy production An analysis of the present certification requirements of the quality management systems of granular and powder metallurgy production is given; suggestions on requirements fulfilment control by the certification bodies of the quality management systems as of exercising activities by them are offered. PRODUCTION ORGANIZATION Krasnopevtseva I. V. — IT as a growth factor of working efficiency at industrial enterprises Necessity or information of industrial production with a view or increase of its efficiency is proved. The analysis of influence of information security of the enterprises on a labour productivity level is load. The basic problems, interfering universal introduction in manufacture of information technologies are revealed influence of the human factor on efficiency of use of information resources is noted.
