Aktualnym i uniwersalnym podejściem do analiz wymiarowo-dokładnościowych i kompleksowych zadań, zapewnienia dokładności i zamienności konstrukcyjnej w montażu jest teoria łańcuchów wymiarowych. Podejście to oparte o aparat teorii łańcuchów wymiarowych (ŁW) jest wystarczająco dopracowane, mimo iż istnieje szereg nierozwiązanych zadań, np. związanych z obliczaniem dokładności parametrów geometrycznych...
This paper presents the method of assembly-oriented design with the use of DFA Expert computer software. The use of this method for analysis and redesign of the assembly product "Polimag" allowed to reduce the number of parts almost by half and to cut the estimated production cost appreciably.
Accelerated method of preparation for assembling for small-scale instrument engineering implemented in a new software environment AsCAM has been presented. It has been demonstrated that the use of such software environment with relatively small amount of input data allows to get a solid solution and furthermore to reduce the preproduction preparation time.
This article presented a new solution to the problem of forming a mathematical model of an automated assembly in the form of binary relations of movement restrictions on 3D models created in CATIA. Shown that the use of new software lets you analyze an large assembly, is practically in polynomial time.
The article presents the implementation of a prospective model of computer-integrated manufacturing for a flexible assembly manufacture based on the interconnected model of the object assembly process design technologies and production models.
The product design has a significant influence on assembly processes and, thus, production costs. This paper presents an algorithm for analyzing and improving the product design. The algorithm uses the BRRR assembly model and the assembly sequence matrix for the assembly process representation. There is an opportunity for computer-aided generating these models on the basis of the products 3D model,...
