We have considered optimization of casting design in the concept of its interaction with two fluid technological mediums, namely, the interaction of its pattern with a sandy medium and the mould ‒ with metal. A metal saving method is proposed and an overview of publications on technical castings design according to this method is presented. The exa...

... examples of the golden section ratio can be found in the human body, as it can be seen in Fig. 1 presenting the illustrations from open Internet sources. One of the modern examples of the golden ratio application is the use of the Penrose tiling [5]. The proportion of the golden section is perceived by the human eye as beautiful and ...

... some photos (Fig. 3), (Fig. 4) we can see the spiral elements, which are analogous to those shown in Fig. 1 and Fig. 2. The examples of thin-walled cast ornaments, consisting of such elements, are shown in Fig. 5. Figure 6 shows the ratios of hand sizes, corresponding to the Fibonacci numbers, as well as the cast sculptures of hands, made from ferrous and non-ferrous metals. In Fig. 6 the second image from left shows the cast sculpture of ...

In Fig. 14 c) shows the cavity, cut out in the polystyrene foam block by the 3D-mill and intended for further production of mold pattern, polystyrene foam pattern and cast iron casting of the decorative fence detail. This practically shows the cycle of ...
