Methods for modernization of processing equipment

Abstract

Industry dynamics determines the improvement of manufacturing processes and necessarily implies the development and evolution of technological equipment for machining, assembling and controlling. The modern technological concept requires multicriteria optimization of the technological system, emphasizing its ability to adapt precisely, quickly and efficiently to the variation of production tasks. This paper proposes a combined method of optimization of technological processes capable of overcoming the difficulties caused by the complexity, diversity and dynamic character of the processing equipment in order to make objective technical and economic decisions. The in-depth analysis of optimization problems for technological processes and equipment is required by the need to respect the multitude of conditions and their interdependence and has as main objective the establishment of rational solutions in the field of manufacturing engineering. For a technological process, in the first stage, based on a technological chart, several processing procedures are analyzed depending on the complexity of the semi-finished products and the type of machine-tool used, and with the mathematical model associated determine the number and optimal sequence of operations. In the second stage, an optimal variant of the process, presented as a combination of processing procedures, is analyzed with the global utility method, especially in the nodes with several operations, as special or modular structures and the optimal solution for the construction of the devices and machines -tools, technological equipment in general.
