Ruzmetov A. Increasing of efficiency of metalworking at the expense of accounting changed of work ability the main workers

Dissertation is devoted to solving the problem of the efficiency technological operations of the metal cutting by obtaining more corresponding to actual conditions of real production, of the time standards of the preparation automatic operation of process equipment taking into account the changes in the work capacity of the main workers in all working time. Object of research - processes, which is implemented on an automated machine tools in small-scale engineering production. The purpose of research - increase the efficiency of the complex of organizational-related, technological mechanical cutting operations implemented on automated equipment to small-scale production by reducing manufacturing cost by forming a rational organizational and technological structures of the machine and manual processing operation, taking into account the major phase changes of working capacity of workers. Research methods are based on the main provisions of manufacturing engineering, standardization of auxiliary time, production organization, fuzzy set theory, information theory, mechanics and ergonomics. The formalization of technology decisions by a frame-based production models and knowledge. For create the complex of software design MMTO used the method of structural and algorithmic synthesis and theory of object-oriented programming. Research of work of the production system carried using GPS simulation system. Used equipment - computers. Created the mathematical models of functional relationships between performance, reliability of technological operations and work capacity , typical and algorithmic complexity of its subsidiary processes that allow form groups technological operations for many machine tool service with a fairly high level of use of machine tools. Scientific novelty of the results is that, based on the system analysis of regularities of formation of the temporal structure of the machine and manual processing operations for the first time solved the problem of improving the efficiency of the complexes organizational interconnected technological operations cutting which implemented on automated equipment, by taking into account influence of the work capacity of the main workers on its functioning. Results of the study implemented under the rationing machine and manual technological operations of modernized technological process of the part "cylinder block" , performed by the company State Enterprise «Kharkiv machinery building plant «FED»; under the modernization of the organizational and technological structure of the manufacturing site of repair of the roll mill, LPC-2 enterprises of JSC "Severstal" (Cherepovets, Russia). Scope of application - engineering.
