Formulation of laws of provision for accuracy of article during assembly based on modelling of its production process

Subject of investigation: article assembly process. Purpose of the work: reduction of labour consumption of technological preparation of article production by computerization of design and reduction of cost of article manufucture by way of the rational assignment of allowance. Laws are determined for the action of the design-technological factors in the course of the article assembly. The rules are formalized for the construction of a geometrical model of a part and an article. Methods are proposed for the solution of a primal problem of the spatial dimensional analysis. A complex of problems is developed for the computer-aided formation of mathematical models of parts and articles. A complex of programs is developed for the calculation of parameters of the component links of the spatial dimensional chain. The subsystem of formation of the initial information and the subsystem of the dimensional analysis of the computer-aided manufacturing design of the article assembly are being put into practiceAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
