ABSTRACT

Purpose. Development of elements of programming on equipment with numerical software control in end-to-end technologies of manufacturing mechanical equipment in mechanical engineering.

Method. It represents the analysis of scientific and technical information on "digitalization" in the development and issues of development of end-to-end technologies for the manufacture of mechanical equipment in mechanical engineering and the synthesis of tasks and development.

The results. It is shown that the generally accepted technology for the production of metal parts and, accordingly, units of aggregates and machines in mechanical engineering consists of the main sequential technological operations: cutting of rolled blanks; forging or stamping of finished parts or forgings and stampings for subsequent mechanical processing by cutting; casting of finished parts or cast blanks for processing; processing of forgings or stampings and castings by cutting; if necessary, heat treatment of parts; if necessary, covering of parts; - assembly of nodes and machines. The given examples for each component technology showed a wide range of numerical software control products.A model of components in the "digitalization" of mechanical equipment manufacturing technologies and a model of the main components of the end-to-end technology of manufacturing metal engineering parts and "digitalization" elements have been developed.The relevance of developments on smoothing the joints of lines describing the shapes of product details is substantiated. It is proposed to use the possibilities of Bezier lines more widely.

Scientific novelty. The elements of scientific novelty are in the created model of "digitization" of the components of end-to-end technologies for the manufacture of mechanical equipment in mechanical engineering and in the formulation of the application of Bezier lines for smoothing the joints of tool movement lines in the development of technological processes.

Practical significance. The results of the article can be used in the development of end-to-end technologies for manufacturing mechanical equipment in mechanical engineering.

Keywords: engineering technologies, mechanical equipment, numerical control, software products, CAD-CAM systems, three-dimensional models, Bezier lines.
