CONSTRUCTIONAL MATERIALS, PHYSICAL METALLURGY

Khorev A. I. � Theory and practice of microalloying β-welded titanium alloys by rare earth metals (REM), zirconium, hafnium and rhenium

System research results of the alloying elements influence in concentration broad interval enveloping α-, pseudo α-, (α+β)- and β-alloys are adduced. Microalloying limits of the base titanic material and welding joint by zirconium and hafnium are established. The research results allows to create more than 100 new titanic alloys for utilization in the flying apparatus design.
Key words: titanic microalloying, mechanical characteristics, rare-earth metals

SHAPING TECHNOLOGY

Nikolaev P. M. � Building a smooth toolpaths for high speed milling ensuring

The basic aspects of constructing a smooth motion path of the cutting tool for high speed machining are covered. The proposed algorithm allows the use of standard procedures spline approximation to convert tool path defined as a polyline into a smooth spline. The accuracy requirement on straight segments is taken into account. Algorithms for constructing smooth approach and retraction cutter to separate sections of the path are discussed.
Key words: high-speed milling, smooth tool path, cutter lead-in

Key words: surface layer, modeling, cutting, coating PVD

MACHINE-TOOL AND CUTTING TOOLS PRODUCTION

Grigorev V. S., Mironychev N. A. � Interconnections of the applied resources at cutting tools shaping

The correlation of geometrical resources applied in geometrical bodies forming at hierarchical levels from point to spatial from a synergetics approach (position) is described. It is displayed that surface geometrical resources serve for blade cutting tools forming, but surface and volume resources for abrasive tools.
Key words: geometric body (solid), resource, correlation, hierarchy, synergetics, tool geometry, form-building elements, abrasive grain, abrasive tool

It is considered the building possibility of the internal (shape-generating) kinematic chains gear for gear-shaping machines of various technological purposes in the form of hydraulic connections based on stepping hydraulic drive in order to improve the accuracy, reducing specific quantity of metal, creating a rational design of the machine, using aggregate modularity principle.
Key words: desktop, gear-shaping machine, hydraulic, modular principle

MACHINE ASSEMBLE PRODUCTION

Kopylov L. V., Petukhov S. L., Bukhteeva I. V., Feofanov A. N. � Improving ensuring accuracy of ensuring functional index rotor aggregate functional index

This article contains the data on the new method of assembling rotor units, which allows to minimize the radial air gap between the stator and the rotor and to ensure its regularity. The distinguishing feature of this method is the regulation of the gap in the assembly process with subsequent fixing it using the compound. The method provides a productive assembly of rotor units. An important difference of this method is the minimization of the additional requirement of improving the accuracy of the assembly units and the aggregates.
Key words: rotor, stator, assembly, regulation, radial air gap, compensator

RECEIPT TECHNOLOGY OF THE PERMANENT CONNECTIONS

Velichko A. A., Orlov V. V., Pazilova U. A., Sulyugin R. V., Khlusova E. I. � The structure and properties optimization of the thermal influence zone (HAZ) of the high-strength pipe steels welded joints

In order to establish ways of adverse effect minimization of the welding cycle we studied influence of the heat input at multiarc flux welding and of welding practices on the structure and properties of the high-strength pipe steel welded joints in the heat-affected area. The analysis of the obtained data allowed to ascertain a processing method which significantly reduced weld microhardness and step-up fraction of ductile fracture of percussion samples.
Key words: pipe steel, multiarc welding, flux, microhardness
