Khudyakova E.O., Purtov A.S. Tool adjustment for the nanometric precision lathe

Tool adjustment for the nanometric precision lathe

Khudyakova E.O., Purtov A.S.

The paper refers to mechanical engineering, namely, to the field of high precision lathes manufacture and can be used to solve the problems of tool adjustment for automated machining the objects featuring a complex dimensional profile that claims high demands on quality and precision of the machined surface. The surface is processed by turning (a lathe cutter) on the working surface of the functional blank layers (for example, metalloptical mirrors). For this purpose, nanometric precision lathes provided with a numerical control system (NCS) are used. Current techniques of tool adjustment are analyzed, as well as their drawbacks. The paper presents a new way of tool lathe adjustment using high precision optical laser sensors that makes it possible to upgrade positioning accuracy up to 0.1 mkm.

Keywords: NCS machine, lathe tool adjustment by means of a laser sensor, adjustment of lathe with optical indexation system.

Karpov A.V. Revisiting power efficiency estimation of technological processes of cutting

Revisiting power efficiency estimation of technological processes of cutting

Karpov A.V.

The paper deals with the problem of efficient energy resources consumption when processing blanks of machine parts by means of cutting tools. The energy efficiency increase of technological processes is considered as a necessary factor to ensure national production competitiveness of the mechanical-engineering complex. The problem of increasing energy efficiency of the cutting process is multi-staged. The paper considers a number of techniques to optimize the provisions for the cutting process: geometrical parameters of the cutting part of the tool and the values of processing modes. The paper presents a new integral index of energy efficiency (power efficiency) of the cutting process, which is, in fact, a ratio of processing energy density to the processed material strength. The paper gives a number of calculation-empirical methods to determine energy efficiency criteria, following the example of processing a rectangular groove by a horizontal milling machine disk cutter. Implementing the optimization technique can reduce energy costs in the cutting zone by 12-18% compared to the processing provisions based on the modes provided in General mechanical-engineering reference books.

Keywords: mechanical engineering, technological system, materials cutting, a cutting tool, power efficiency, energy expenses, power consumption.

Vasylkiv V.V. The application of air plasma cutting process for manufacturing screw and auger blanks

The application of air plasma cutting process for manufacturing screw and auger blanks

Vasylkiv V.V.

In the technological route structure of manufacturing screw parts the formation of screw and auger blanks is considered to be the most critical and complicated stage. For the first time, an effective technique to manufacture these blanks in order-, serial- and mass production has become possible when using air plasma cutting process along the helix of thick-walled pipes and single hollow blanks. Applying this technique, metal and polymer screw and auger blanks can be manufactured, which were difficult to process by pressing and cutting. The provisions for the efficient use of the new technology are considered. The technical solutions under discussion make it possible to manufacture a number of screw blanks, including working parts of screw mixers, separators, presses, shredders, centrifuges, screw conveyors, screw broaches, cutters, screw piles, anchors, drills, screw pump rotors, screw plows, etc.

Keywords: screw flights, screw blanks, screw part, air plasma cutting.

The analysis of surface water pollution in Vladimir region

Sharapova E.V.

The paper presents the analysis on surface water pollution in Vladimir region. The description of water bodies is given. About 120 million m3 of polluted water is annually discharged into the surface water. The analysis of gross pollutant discharges into surface water bodies is performed. The analysis shows a slight decrease in the amount of pollutants in the wastewater. But in spite of this fact, pollutant concentration in the surface waters is still high, and, as before, it requires certain decisions and activities towards better and more complete wastewater purification in Vladimir region. The list of major manufacturers involved in polluted wastewater discharge is given as well. The estimation of rivers pollution in Vladimir region and its time history analysis are presented. Nitrite nitrogen, copper, phenols, petrochemicals and iron are considered to be the main pollutants of major rivers in Vladimir region (the Oka River and the Klyazma River).

Keywords: rivers, surface water, pollution, waste water, water.

The paper presents the analysis on possibilities and problems when performing physical ways of separating fine loose materials. Continuous growth of mineral raw material consumption together with concentration reduction of necessary chemical elements in ores, as well as increase in quantity and the nomenclature of production wastes and consumption, demands more widespread introduction and improvement of physical ways for separating fine loose materials. In a freefall mode of loose material weight in the gravitational field the separation method is not used when performing different ways of magnetic, electrodynamic and electric separation (except for triboelectrostatic separation). Special attention is paid to the importance of applying a freefall mode of loose material weight in the gravitational field, as well as using pulse modes in electrodynamic separation in order to enhance separation efficiency.

Keywords: magnetic, electrodynamic, electric and X-ray radiometric separation, fine loose materials, mineral raw materials, production wastes and consumption.

Lodigina N.D. Calculations on pile foundations on karst territories

Calculations on pile foundations on karst territories

Lodigina N.D.

The analysis of major accidents caused by karst deformation shows that in every case the mistakes have been made at different stages of construction: site selection, engineering survey, design, facilities construction and their operation. The paper presents calculations on stress-strain state of the pile strip foundation in the course of karst hole formation. The pile design scheme is presented as a rod elastically secured into the ground at one end while the other end has a pivotally-fixed pairing with grillage and load linearly increasing on the pile. The paper defines pile deformation (displacement, cross sections rotation angles), bending moment and strains in the pile, depending on variable z, which values range from zero in the joint to 1in a tight sealing. This calculation technique makes it possible to perform the power analysis of forces acting on the pile in karst holes caused by the caving-in horizontal soil pressure, as well as to do all kinds of calculations on piles (including test, design and load capacity).

Keywords: calculations on pile foundations, karst, strain, deformation, technique.
