Evaluation of manufacturability for the effective decomposition of product when layered build

Abstract

The 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.
