COMPLEX METHODS OF TOOLING OF DETAILS WHICH WILL REALIZE FEATURES OF DYNAMICS OF TECHNOLOGICAL SYSTEM OF MACHINE-TOOL

Abstract. Proposed methods for machine processing complex surfaces of parts which are based with due account taken of the dynamic properties of the technological system of the machine. Developed tools and equipment for machine processing parts by melting the surface layer and the formation of the machined surface with a given waviness, which depends on the adjustment of the dynamic parameters of equipment, which determine the general dynamical properties of the technological system of the machine. Determined the regularities of the work processes flow of molten metal at thermoclutch processing. Theoretically studied the dynamic oscillatory processes in the technological system. The results of mathematical modeling accord with experimental data. The experimentally determined waviness and solidity of the machined surface. Performed spectral analysis of waviness with definition of the characteristic harmonic components of the profile. Studies are supplemented by electron microscopy and by measuring solidity of the surface. It is shown that the solidity of the machined surface in 2 .. 4 higher than the solidity of the workpiece. There was grounded the possibility of obtaining discontinuous surfaces with high anti-friction properties and surface alloying components during processing.

Keywords: disk instrument, melting of surface, working process, oscillation table, dynamics, mathematical model, flow diagram, vibrospeed, draft treatment, surface, profil, spectral, analize histogram of ordinates, electronic photomicrograph, finish operation, hardness of surface.
