Abstract
Relevance. The modernization of production is one of the priorities for the development of enterprises. Technical upgrading of enterprises is possible either by replacing equipment or by modernizing the machine pool. At the same time, there are various options for the modernization of CNC machines, for instance. Every option has positive and negative aspects. Organizing the modernization of CNC machines in defense enterprises is associated not only with the selection of one of the options, but also with additional difficulties, such as compliance with technologies, import substitution, requirements for the fulfillment of state defense orders, etc. Moreover, the modernization of CNC machines may pursue different goals and solve different problems. The objective of the study is to analyze the conditions for organizing the modernization of CNC machines in defense enterprises, objectives and typical problems of modernizing CNC machines in a defense enterprise, as well as to determine the ways of its implementation. Materials and methods. The research is based on a panoramic approach to the discussed problems, objectives and options for modernizing CNC machines in defense enterprises. The decision to organize the modernization of the machine pool of the defense enterprise is integrated, and is made taking into account internal and external factors, as well as the options for its implementation. The rationale for a feasible option is given based on the analysis of various types of the modernization of CNC machines at manufacturing plants of the military-industrial complex, their advantages and disadvantages. The analysis is also based on the generalization and structuring of the problems arising during the organization of the modernization of CNC machines at the enterprises of the defense industry, as well as during their commissioning. Results and Conclusions. The analysis shows that the replacement of an electronic part of CNC machines is the most feasible type of modernization. But as for CNC machines of different generations, the technical implementation of new electronic control units should be different. This is due to the interface with either a phase or discrete control system of outdated machines. Despite this, the modernized machines are to be integrated into a single technological space, have a common interface, and work according to the same algorithms. The concept of a unified approach to the modernization of CNC machines in defense enterprises is defined from these positions.
Keywords
