Prospects for CNC Machine Tools
Russian Engineering Research - Tập 39 - Trang 1080-1083 - 2020
L. I. Martinova, G. M. Martinov
The main global trends in the production of high-technology CNC systems are identified. Topics analyzed include system architecture; the use of high-speed industrial networks based on fieldbus technologies; the potential of multiple-channel and multiple-axis machining; spline interpolation in the machining of complex contours and free surfaces; and five-coordinate machining with 3D correction of t...... hiện toàn bộ
Monitoring of electric discharge machining by means of acoustic emission
Russian Engineering Research - Tập 36 - Trang 244-248 - 2016
M. P. Kozochkin, S. N. Grigor’ev, A. A. Okun’kova, A. N. Porvatov
Electric discharge machining is accompanied by acoustic-emission signals, which may be used monitoring, diagnostics, and control of the process. Experiments show that the acoustic signals permit assessment of the efficiency of the current pulses supplied and optimal technological adjustment.
Comparison of the Surface Texture of a Crankshaft after Grinding and after Burnishing
Russian Engineering Research - Tập 40 Số 11 - Trang 939-941 - 2020
И. Н. Бобровский, П. Ф. Зибров, Н. М. Бобровский, Ф. В. Гречников
Quasi-Determinate Model of Thermal Phenomena in Drilling Laminates
Russian Engineering Research - Tập 38 - Trang 1074-1076 - 2019
S. V. Vantsov, F. V. Vasil’ev, A. M. Medvedev, O. V. Khomutskaya
Assessment of thermal phenomena in the drilling of laminates is critical in printed-circuit production. A quasi-determinate model permits calculation of the expected temperature in the cutting zone during the drilling of small mounting sockets and pass-through holes, with consequent decrease in manufacturing waste.
Structural synthesis of machine-tool configurations
Russian Engineering Research - Tập 37 - Trang 335-337 - 2017
M. Yu. Lekhmus, R. F. Amirov, S. I. Fetsak
The goal of the present work is to present the basic formalization parameters — that is, the initial data for computer-assisted design of metalworking equipment on the basis of early selection of its configuration.
Hydrodynamic supporting bearings with initially plane-parallel slip surfaces
Russian Engineering Research - Tập 29 - Trang 234-239 - 2009
V. A. Maksimov, A. V. Paladii, T. V. Maksimov, E. A. Novikov
The procedure permitting to calculate the thrust bearings with initially flat immovable pads is given. In the procedure the dimensionless performances obtained on the base of elastohydrodynamic theory of lubrication are used.
Efficiency of Waste-Heat Power Units in Spacecraft Thermal Control Systems
Russian Engineering Research - Tập 40 Số 7 - Trang 602-604 - 2020
N. O. Borshchev, А. Е. Сорокин, A. E. Belyavskii
Quality control of rolled threads
Russian Engineering Research - Tập 35 - Trang 143-146 - 2015
M. Z. Khostikoev, V. U. Mnatsakanyan, V. A. Temnikov, Wei Pyu Maung
The thread quality and the microstructure and microhardness acquired as a result of machining by rolling are investigated. The characteristics, distribution, and depth of the deformed layer formed on rolling a threaded surface are established experimentally. The results indicate that rolling may expediently be used to improve the precision and surface roughness of thread and to increase the streng...... hiện toàn bộ
Centrifugal-gyrational mill with no counterweight
Russian Engineering Research - - 2013
E. S. Askarov
Selecting abrasive wheels for the plane grinding of airplane parts on the basis of surface roughness
Russian Engineering Research - Tập 30 - Trang 251-261 - 2010
Ya. I. Soler, D. Yu. Kazimirov
The machinability of hardened Cr-Mr-Si and Cr-Mr-Si-Ni steels and the efficiency of traditional abrasive wheels are analyzed on the basis of parametric and nonparametric data. The applicability of the wheels is discussed.
