Under conditions of automated production the matter of ensuring the required parameters of surface layer quality in machine parts at machining becomes urgent. To ensure the required quality parameters of a surface layer (QPSL) in machinery at mechanical oper-ation there are used simulators predicting their values depending on working modes. At the ensuring of QPSL in machine parts at mechanical operation occurs uncertainty connected with the absence of univocal simulators predicting QPSL depending on working modes. One of the methods to solve the uncertainties existing consists in the instruction and self-instruction of a technological system during control and application of obtained and accumulated information at adaptive control. And at the same time the problem of parametric identification at the adopted structure of a simulator is solved. The parametric identification of simulators is carried out by a self-learning technological system of control (STSC). The developed STSC is intended for ensuring the specified parameter of roughness Ra , sur-face residual stresses, surface micro-hardness and the complex quality parameter of friction surface Cx. The algorithm of system functioning is realized as a soft-ware loaded in memory of a control device.

Surface Layer Quality

Dependences for determining geometric, physical and mechanical parameters of the surface layer quality, wear resistance, corrosion rate and endurance limit depending on the modes and conditions of electroerosion treatment of machine parts have been given. These dependences allow determining optimal modes and conditions of electroerosion treatment to ensure the required parameters of the quality of the surface layer (with a two–stage approach - design and technological support of operational properties), wear resistance, corrosion rate and endurance limit (with a single-stage approach - direct technological support).

Abstract The main idea of the work is to create a physical model of high speed broaching heat-resistant materials is used to study the parameters of the surface layer quality. Modelling is a method of mediated cognition, in which the object under study is in some correspondence with the model, and the object-model is capable in some way or another to replace the original at some stages of the cognitive process. Physical modelling is primarily distinguished by the fact that studies are conducted on models with physical similarity, i.e. preserving completely (or at least partially) the nature of the phenomena. The work of the broach can be likened to the work of a number of planning cutter displaced relative to each other by a small amount, which is called lifting (feed per tooth). Therefore, for experimental work, a planning cutter of a special geometric was designed and manufactured – a physical model of a broach, in which geometric, mechanical and dynamic similarity is realized. The article also presents an experimental justification for the use of the created physical model in the study of the surface quality parameters of the, tab grooves of turbine and compressors disks made of heat-resistant materials.

Surface Layer Quality

It is shown that the magnetodynamic treatment implemented under the conditions of a rotating electromagnetic field is a kind of the dynamic methods of hardening free-moving indenters by the convection flows. It is proposed to use analytic dependences obtained by the approximation of the test data of effect of the surface plastic deformation (SPD) dynamic methods on the component hardened layer quality to evaluate quality parameters of the surface layer formed under the magnetodynamic processing. The resulting expression describing the experimentally established fact that the main contribution to the formation of the quality parameters of the hardened layer is made by the initial continuous coating of the treated surface with plastic prints is obtained. An analytical functional model establishing the surface layer quality parameters behavior depending on the multiplicity of covering the surface by the shock-pulse impact of the free-moving indenters is proposed. A comparative analysis of the experimental data obtained in the process of the magneto-dynamic processing with the calculated ones shows the applicability of the proposed models for predicting quality parameters of the hardened surface layer.
