Prospects for Сomputer-Aided Design of Castings

Abstract

In the study on limiting possibilities of a casting process in terms of resource saving it is considered which solidstate constructions can optimally fill the space of the mold. The possibility of designing patterns for the Lost Foam Casting process in accordance with mathematical concepts is shown. The examples of patterns of frame cellular castings are described. The examples of cellular castings, designed with the help of computer technologies, are shown that often inherit structures of nature. Such castings allow expanding of the existing range of properties of metal products.

Mathematical Relations for Harmonization with Technical and Decorative Casting Nature

“…Method of copying in metal nature structures, selected by evolution, as innumerable examples of perfection and resource saving, has a great potential [4], [5], in particular, using the LFC process.…”

“…With the help of mathematical and computer modelling it became possible to develop lightweight cellular resource saving constructions of cast metal products by analogues of microstructures of solid substance, some biological structures and nanomaterials with their physical modelling from serial parts, made from gas-filled hydrocarbon polymers [2]- [5].…”
