Hexagonal grid cylindrical latticed shell structure is proposed, due to honeycomb structure (although the hexagon structure) is the most effective structure on save the building materials.
Connecting the nodes in sequence on the basic of the description rules of the nodes, and then to make the geometric model completed. 3) Material property and the type of members.
The process of calculation and analysis showed this method feasible. 2) The regular hexagonal latticed structure, as also the honey structure, can effectively save building materials, and the regular hexagonal grid with sparse distribution of member can create a simple and transparent visual effect.

Die assembly is a kind of special tools for fabrication of metal or non-metallic materials parts with required design and purpose.
In this paper, the machining strategies for fabrication of die assembly with typical shaped cavity using EDM were discussed, according to the different cavity structures, the best machining strategies were proposed Introduction With the development of material science and industry progress, a large number of high strength, high hardness, high toughness, high brittleness, high temperature and other special properties of the mold material have been applied more and more widely.
EDM is mostly used in die and mold making, where complicated shapes in hard materials and with high precision have to be machined.
