Feasibility evaluation of using additive technologies in aerospace products
The paper studies the feasibility of using additive technologies in the manufacture of parts of complex shapes for aerospace products. The results of the structural analysis of a part helped find the directions of topological optimization and optimize the part’s design. To confirm the relevance of the design optimization, we carried out static and dynamic strength calculations in the Siemens NX software package. The paper considers technologies for manufacturing the part by 3D metal printing and traditional milling on a numerically controlled machine. In order to obtain initial data for economic calculations, we simulated manufacturing processes in various software systems. To study the feasibility of metal printing technology, we carried out its technical and economic analysis, and found that the production program, technological processing modes and the cost of materials affect the cost of the product.
