TECHNOLOGIES AND EQUIPMENT FOR MACHINING, PHYSICOTECHNICAL PROCESSING, NON-CUTTING SHAPING

Demidov V. V., Guskova Ye. V., Polyanskov Yu. V. � Tooth profile accuracy of the wheel machined by involute gear hobbing cutters with positive rakes

Influence of involute gear hobbing cutters profiling by computer simulation method on the base of involute, convolute and Archimedean worms, number of starts and value of the positive face angle of the mill teeth on cylindrical wheel teeth profile error of 3 mm module and with teeth number from 20 to 135 is investigated. Teeth profile expected error prediction technique after gear milling on a machine with involute gear hobbing cutter with positive face rakes is suggested.
Key words: by involute gear hobbing cutter, profiling methods, cutter face angle, tooth profile error, efficient milling cutter life

Pimenov D. Yu., Guzeyev V. I. � Compliance calculation of the unit milling cutter � arbour at face milling

The given article describes the process of strain of a mill and a mill arbor by means of traditional equations of theory of elasticity. The compliance of the mill and the mill arbor along the axis of mill�s rotation that forms the machined size at face milling is calculated.
Key words: face milling, compliance, mill, mill arbor, unit, processing, strain

Yemelyanov S. G., Yatsun Ye. I., Shvets S. V., Remiyev A. I., Pavlov Ye. V. � Stressed state regularity in the cutting area

Using phenomenological theory calculation of stressed state and of fracture criteria in the cutting area is carried out. This makes it possible to prove an equivalent participation of compression and bending in the process. Physical relations are established in the cutting system, which favours forming actual mechanism of chip forming.
Key words: deformation, chip forming, compression, bending

TOOLING PRODUCTION

Mokritskiy B. Ya., Burkov A. A. � Selection of an effective metal-cutting tool for lower-group hard alloy lathe machining

According to performance criteria radial surface abrading of hard-facing alloys, including tool hard alloys is not admissible. Results of edge metal-cutting tool processing are covered.
Key words: sormite machining, stellite, ��20/VK20, ultra-hard tool material

Tabakov V. P., Chikhranov A. V., Smirnov M. Yu., Osipov M. A. � Machining tool multiple abrasion resistant coating on the base of modified titanium nitride

Estimation procedure of the cyclic crack growth resistance of the machine tooling sandwich wear-resistant coating and design data on cyclic crack growth resistance estimate are covered. It is shown that increase of cyclic crack growth resistance results in lower cutting tool wear rate and accordingly in higher effective tool life.
Key words: cutting tool, wear-resistant sandwich coating, crack growth resistance, wear, high-beat state, resistance period

MACHINING-AND-ASSEMBLY PRODUCTION

Zorina Ye. M. � Structure principle improvement of the system of limits and tolerances

Development results of a new tolerance value table based on the principle of golden section are given. A step-by-step construction process of the above said table is shown. Tolerance values have become tougher, which calls on the times in connection with application of high-precision equipment.
Key words: tolerance, nominal dimensions range, golden section, workmanship

Arkhipov V. Ye., Londarskiy A. F., Melshanov A. F., Moskvitin G. V., Pugachiov M. S. � Steel combined strengthening by gas-dynamic treatment

On the base of durometric analysis data a possibility of strengthening steel 40� by corundum up to 2�10�4 in depth using gas-dynamic equipment is shown. Obtainable degree of strain hardening is 25 per cent. Static loading fracture strength test allowed for optimizing corundum process parameters. Combined gas-dynamic treatment by solid and plastic particles does not lower hardening effect and may become a prospective approach to higher resource of steel pieces.
Key words: surface plastic deformation, coating, hardness, strain hardening, strength, plasticity
