Opis:: In the era of smart manufacturing and Industry 4.0, the rapid development of modelling in production processes results in the implementation of new techniques, such as additive manufacturing (AM) technologies. However, large investments in the devices in the field of AM technologies require prior analysis to identify the possibilities of improving the production process flow. This paper proposes a new approach to determine and optimize the production process flow with improvements made by the AM technologies through the application of the Petri net theory. The existing production process is specified by a Petri net model and optimized by AM technology. The modified version of the system is verified and validated by the set of analytic methods safeguarding against the formal errors, deadlocks, or unreachable states. The proposed idea is illustrated by an example of a real-life production process.

Opis:: Rapidly rotating systems such as centrifuges are widely used in medicine and laboratories to efficiently separate different constituents of liquids. Rotors, which hold sample containers, are an essential part of centrifuges. Since they are subjected to extreme mechanical loads, rotors are one of a centrifuge’s core safety components. Their deficits served as the point of departure for the development of a novel manufacturing technology, which is based on carbon fiber-reinforced polymers (CFRP). Its supporting structure is entirely in the loading plane, thus enabling the rotor to absorb higher centrifugal forces while requiring the same amount of material. The new design concept for the load-bearing structure includes a geodesically molded annular support member. It transmits forces better than present products and increases rigidity. In order to eliminate the known problems with obtaining the necessary manufacturing quality of hollow fiber composite bodies, the authors developed the process of centrifugal infusion. Their proposed solution is based on generating higher gravitation forces, thus effectively eliminating detrimental gas pockets and simultaneously optimizing surface quality and impregnation.
