Parshyn Y. The increase of efficiency while mechanical processing of steel articles 38ХН3МФА having characteristics of high reliability

The large 38XH3MФА steel articles. The investigation of mechanical processing of alloy steel articles with characteristics of high reliability. The methods of investigation - the methods of mathematical planning of the experiments, the optimisation, the statistical processing of the data and the mathematical computermodelling. There have been got the exponents showing the dependence of the influence of the range of mechanical characteristics on the speed of cutting. There has been investigated the influence of cutting regimes on the quality of mechanical processing. There have been designed the methods of the optimisation of mechanical processing. Some new models of the cutting tools have been supplied. A complex of completely new engineering solutions aimed to increase the efficiency while mechanical processing has been applied to production. The sphere of application is heavy machine-building.
