Nahornyi V. Control dynamic behavior of metal-processing systems and method of determining their life.

The work is devoted to the actual problem of control dynamic behavior of metal-processing systems and method of determining their life. For the first time solved the scientific and technical problem of forecasting resource of the metal-processing systems in the course of their work turning without the use of statistical data on the working time of the metal-processing systems to replace it. This problem is solved with the help of a predictive model, in the mathematical structure, which enabled the desired metal-processing systems life. A resource is defined in the identification process model, based on the results of monitoring the trend of information parameter, accompanying the working process. In order to implement operational control of the mashinig developed forecasting system was automated with the help of specially developed for this purpose microprocessor-based controlo - prognostic system, that allows simultaneous with forecasting control the quality of machining and diagnosis the technical state of the tool and machine. Methods: cutting theory, oscillation theory, identification and mathematical statistics. System design, was based on the methods of information technology. Experimental data, were analyzed, based on the theory of digital signal processing. To solve the problems prediction used methods of random search .
