Abstract
The issues of transferring the production of parts manufactured by cutting at the qaz Carbon LLP plant to casting in gypsum molds are considered. A methodology for designing the technological process of casting plaster molds using computer modeling is proposed. This method allows you to reduce material and financial costs, as well as reduce the time of mastering the production of parts by sand casting. One of the methods of casting is the production of castings, which provides a sharp increase in labor productivity. Using the Flow – 3D program, it is possible to significantly simplify the casting process, and forms are created taking into account the progress of the process of transition of the material from a liquid state to a solid state. The work calculates casting defects, stresses and deformations. Optimization of the technological process based on the results of modeling the casting process by preparing the casting «bearing shield», reducing the amount of nutrients of the casting system, increasing the output coefficient of suitable casting, a 3D model core model is developed for the development of control programs for the production of equipment on CNC machines
