Документ Evaluation of manufacturability for the effective decomposition of product when layered build(Editura "Academica Brâncuşi", Târgu Jiu, 2017) Garashchenko, YaroslavThe possibility of evaluating the manufacturability of product on the basis of a statistical analysis of the elementary volumes distribution of original 3D model is considered. The proposed indicator allows for quantitative evaluation of the efficiency of applying structural reversible decomposition of a product in order to rationally place it in the workspace of layered build of additive technology installation. The definition of manufacturability index is carried out according to the proposed algorithm for analyzing the distribution of product material in workspace. The algorithm is performed by using voxel 3D-model of product. Approbation of the proposed evaluation algorithm is performed on the example of test models of industrial products. The estimated data for determining the manufacturability level is presented depending on division parts number of workspace with the product. The results show sufficiently high degree of confidence and informative for development of design and technological preparation of additive manufacturing of complex products.Документ Evaluation of geometrical complexity of products based on the analysis of triangulated models(Editura "Academica Brâncuşi", Târgu Jiu, 2017) Garashchenko, YaroslavThe results of study evaluation possibilities of geometric complexity of industrial products are presented in this article by analyzing of functional dependence of number of triangular faces on triangulation parameters. As the main parameter of the triangulation was considered maximum size of edges. The dependence study was carried out for basic geometric bodies, which revealed the general regression equation. Test of the regression equation on models of industrial products has confirmed put forward a scientific hypothesis on the evaluation possibility of geometric complexity of industrial products based on the analysis of this functional dependence.
