In the LGM-casting process to obtain a model means already half a cast, let us consider this in more detail in the light of current trends. Today, the production of high spatial (three dimensional) products, models, forms, master models made of aluminum, wood, MDF, mock-up of plastics and other associated with the rapid development of computer hardware, software, digital data transmission, as well as improving the drive system of machine tools (the use of servo motors with feedback). Production workers today for prices and a wide range of automated equipment has become available with CNC. CNC supersede any other system management, both at the large automated factories, and the very small, flexible, versatile production (a breadboard model, tool, souvenirs, advertising, repair). This equipment is increasingly used as private entrepreneurs, and serving a broad range of customers specialized areas. For efficient rendering and production of molds, dies, models only need to send them an e-mail three-dimensional image of the product. The indicated availability of computerized systems and CNC served as an impetus for the emergence of a whole class of equipment that allows a drawing to receive details on the computer with the milling CNC ready to mold the metal or its model from polystyrene foam, such as program production, "she allows," the casting shrinkage, as well as allowances for casting and machining. At the same time use the program, that help maximize the potential of these machines with support for 3D-models and turning.
A series of software systems of computer simulation of casting processes to the selection process parameters to develop a design block model 3. Testing of the design of gating and feeding system, temperature and time parameters of the process is not in the shop with the metal on real expensive bathing suit, but in the virtual space of the mathematical model. Short deadlines computer simulations, as well as large volume and clarity of information received on the technological process and as a future castings make computer simulation an important tool for pilot production of an increasing number of factories.
