Description
Summary:The article is devoted to the study of the accuracy of fabrication of the surface layer of engineering products by additive methods. The analysis of the advantages and disadvantages of technology for layer-by-layer synthesis of products took place. It was revealed that with additive fabrication, the accuracy characteristics of the surface layer are significantly different from the characteristics of the surface layer of products obtained by traditional methods. The analysis of domestic and foreign works on the topic of research allowed to reveal that in order to increase the accuracy characteristics of products obtained by additive methods, it was necessary to provide dynamic control of the spatial orientation of the final link of the fabrication system of the additive installation in the process of fabrication. To control the spatial orientation of the working body of additive equipment, the use of mechanisms with a hybrid layout was proposed. The problem of parametric synthesis of a mechanism with a hybrid layout has been solved, which allows to create a space of design parameters that provide, at the early stages of design, the required formative capabilities of the mechanism for additive fabrication with a hybrid layout.
