APPLICATION OF COMPUTER SYSTEMS FOR DESIGNING AND 3D PRINTING OF A FOUNDRY PATTERN WITH VENTILATION CHANNELS IN ITS WALLS

Abstract

Abstract. In the context of the implementation of the "Industry 4.0" concept, digitalization and automation today have become not just the basis of competitive advantage in the production of goods (works, services), in many areas they are perceived as a necessary condition for the organization of production processes. In particular, thanks to the digitization and automation of foundry production in Ukraine, there is an opportunity to create a powerful potential that will contribute to the recovery of the country. Due to the expansion of the use of computer systems for the design and 3D printing of polymer foundry patterns with ventilation channels, it became possible to develop one of the methods of metal casting according to gasifying patterns (LFC) with the use of printed patterns (models), which corresponds to the growing trend of digitalization and automation of foundries processes. This became possible due to the increase in the intensity of evacuation of the products of gasification of printed patterns in the foundry mold using the vacuum of this mold. The developed method allows you to get a total benefit both from fairly fast computer-oriented 3D processes of designing and printing a foundry pattern, as well as from short-term processes of forming and punching out castings due to the use of dry sand foundry molds at LFC. At the same time, the digital transformation of LFC is combined with the resource efficiency of the reversible use of molding materials without changing the current standards of control of metal products of foundries. And the adaptation of production to additive technologies allows direct interaction with the buyer of the product, which is designed according to his individual digital project, with the help of the Internet. The latter corresponds to the concept of "manufacturing as a service" (MaaS). Also, this implementation of the use of computer systems and new digital processes in traditional foundry processes shortens the time gap from the creation of prototypes and tools to the mass production of metal products.
