Рабочая позиция с перекомпонуемыми рабочими системами

High standards for changeover speed and product quality assurance of modern production require new principles for constructing production systems. High productivity and flexibility with a different range of production type can be achieved by using rearrangeable production systems. These systems combine the advantages of aggregate machines and machining centres due to the design features described in this article. The types of assemblies and system elements in the arranged and disarranged state are presented. Algorithms and schemes for the functioning of rearrangeable working positions (RWP) were developed in comparison with the working positions of automatic lines (WPAL).An equation for determining the mean time to failure of the RWP was derived. A system element and its scheme - the intermodular locating element (ILE) - were visualized. Complex factors of the RWP operational reliability were determined according to the particular and complex factors of reliability and maintainability which take into account the features of RWP operation and design in comparison with the WPAL. Methods for determining the reliability and maintainability factors were developed. These methods take into account the structural and functional features of RWP in multiproduct production and are based on the operational reliability of the WPL. The developed solutions correspond to the development trends in modern machine-building production and the development strategy of the Russian Federation. In the conditions of an operating machine-building enterprise, the accuracy of estimating the economic effect requires the use of robust design models implemented both in algorithms and in programs. In future, we plan to develop special software which would allow us to determine the reliability of the rearrangeable working position with respect to the working position with a rigid interaggregate connection.
