“…The labor intensity of manufacturing is of great importance in the cost of manufacturing parts, especially when manufacturing products of complex shapes that have complex internal holes, cavities, and undercuts. In works [4][5][6], methods are given for calculating the labor intensity of manufacturing engineering products, the analysis of which shows that it is often the machine processing time that has the most significant impact on the cost of manufacturing engineering products. Despite the fact that technologists strive to optimize the machining process by using CNC equipment or universal equipment and tools, the ability of production to optimize machine production time is largely limited.…”

“…Modern additive manufacturing methods, such as SLM 3D metal printing, can significantly reduce the labor intensity of manufacturing complex-profile parts [6][7][8][9][10][11]. The described technologies make it possible to produce high-strength engineering products from metal powders of various alloys to produce internal cavities and thin walls.…”

This article describes the technology for manufacturing a metal composite structure of a metal-cutting tool body. The main problem with using metal 3D-printing is its prohibitively high cost. The initial data for carrying out finite element calculations are presented, in particular, the calculation and justification of the selected loads on the drill body arising from metal-cutting forces. The described methodology for designing a digital model of a metal-cutting tool for the purpose of its further production using SLM 3D metal printing methods facilitates the procurement of a digital model characterized by a reduced weight and volume of material. The described design technology involves the production of a thin-walled outer shell that forms the external technological surfaces necessary for the drill body, as well as internal structural elements formed as a result of topological optimization of the product shape. Much attention in this article is paid to the description of the technology for filling internal cavities with a viscous metal polymer, formed as a result of the topological optimization of the original model. Due to this design approach, it is possible to reduce the volume of 3D metal printing by 32%, which amounts to more than USD 135 in value terms.
