Essay

The scientific bases of vibromechanical processing of gas-thermal coverings by razor a abrasive tools with ordinary a super hard tool materials, which include: the peculiarities of mechanical a acoustic interaction of elements of the system "tool-covering-basis" under the combined processing by cutting; thermo power regularities of razor a abrasive processing of coated coverings by a cubic borum nitride tool a ar-tificial diamonds; the peculiarities of stabilization of the starting level of damage of coverings or its general decrease at the expense of dislocational absorbing of the en-ergy of ultra sound oscillations; the peculiarities of unloading of boundary division "covering-basis" from chaotic impulses cutting fordes; methodology of the covering strengthening a intensification of its cutting by means of implementing in the contact zone acoustic energy equal to heat energy; complex evaluation of parameters of the quality of the surface layer under the influence of mechanical a acoustic factors withthe analytic evaluation demphic influence of harmonious ultra-sound oscillations on hardness of strong point flatness of profile.Recommendations concerning the choice of regimes of cutting a vibrations of razor a abrasive vibro mechanical processing of gas-thermal coverings, constructions of machine - tool devices, magnetic stricting instruments have been developed.
