Influence of elastic recoil on the hole precision when reaming thin-walled components

Zheleznov G.S., Andreeva S.G.

Abstract

The finite-element method is used to investigate the elastic surface displacement of a hole reamed in a lug at points where the radial cutting force is applied. On that basis, formulas are derived for determining the distortion of the machined hole surface, with allowance for all the relevant factors.

Isothermal drawing of small boxes from anisotropic oval blanks

Bessmertnaya Y.V., Yakovlev B.S.

Abstract

The forces involved in the isothermal drawing of thin boxes with large radii from anisotropic blanks are considered as a function of the die speed, the frictional conditions at tool–workpiece contact, and the working pressure.

Process model of digital manufacturing

Zarubin S.G., Deev K.A.

Abstract

Simulation of the business process in manufacturing is considered. The main attributes and stages of the business process are described. For the example of automated machining, the business process is broken down into its components. A logical relation is established between the subprocesses (functions). Their inputs and outputs controlling the implementation of the process are described. A process model of digital manufacturing is developed in the methodology of the IDEF0 standard.

Influence of the surface roughness of the electrode tool on the productivity in electric discharge machining of steel

Ablyaz T.R., Borisov D.A.

Abstract

The influence of the surface roughness of the electrode tool on the productivity in electric discharge machining of 38Х2Н2МА steel is investigated. In the finishing of 38Х2Н2МА steel, there is no need to use electrode tools with surface microprojections shorter than 1.1 μm in order to ensure that the roughness of the machined surface corresponds to microprojections of height 1.1–1.6 μm. In practice, the manufacture of electrode tools with microprojections smaller than 1.1 μm is uneconomical.

Influence of diamond paste on abrasive finishing

Muratov K.R., Gashev E.A., Lagunov D.M.

Abstract

Abrasive finishing by diamond pastes is experimentally studied, with variation in the concentration of diamond grains and in the quantity of paste applied to the lap. In the experiments, the optimal quantity of abrasive paste applied to a lap of diameter 220 mm is determined: 75 mg. The productivity is somewhat higher in finishing by paste with a higher concentration of abrasive particles. The roughness of the machined surface is practically independent of the quantity and concentration of the diamond paste applied to the lap; it remains within the same class.

More efficient rotation of excavator platforms

Kuznetsova V.N., Savinkin V.V.

Abstract

In the rotation of an excavator platform, energy is mostly consumed in acceleration and deceleration. The energy consumed in platform rotation may be reduced by uniform redistribution of the load over the whole contact surface, with equalization of the time of load action.

Creep of graphite blocks under irradiation in RBMK reactors

Alekseev A.T., Sergeeva L.V.

Abstract

Computer simulation of the stress–strain state of graphite blocks in prolonged thermal and neutron irradiation is considered, in a three-dimensional formulation. Allowance is made for the anisotropy of the graphite’s thermophysical properties, as well as crack initiation and growth. Creep of the material is taken into account, in the absence of plastic deformation, and its influence on the properties of the graphite blocks is assessed.
