MULTIFUNCTIONAL MONITORING OF DYNAMICAL EFFICIENCY OF LATHES

There the study object is the machine-tool system of metal-cutting. The purpose is to develop the scientifically-methodological foundations of multifunctional monitoring of dynamical efficiency of machine tools at the expense of their certification, prediction and diagnostics of deviations of forming motions from the given ones and from the dimensional efficiency of parts. The mechanisms of dynamical interconnection of spatial elasto-dissipative subsystems of machine tool, cutting process and surface of part with regard to disturbances have been ascertained. The mathematical simulator of machine tool, the technique and the mathematical software of information-dynamical simulation and identification of spatial elasto-dissipative subsystems of machine tool, the analysis procedure of dynamic characteristics of machine tool in the contact point of tool and part with regard to its dimensions and to the non-uniformity of physicomechanical properties have been created. The simulator of cutting process as the dynamical connection has been refined. The construction technique of information simulators of diagnostics has been developed. The technique and the mathematical software of monitoring of dynamic properties of machine tool from the point of formation of dimensional efficiency of part have been created. The techniques and the algorithms of diagnostics of dimensional efficiency and kinematic disturbances have been developed. The study results as the monitoring systems of efficiency of machine tool functioning, state of cutting, dimensions of machined part and certification of machine tools have been introduced in practice. The application fields are the machine-tool works, the enterprises of common machine-building and instrument-making, the special design offices of metal-cutting machine tools.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
