The Methodology of Virtual Foundry Developing

Abstract

Systemic approach to design of factories requires that engineering, organisational and economic aspects should be considered concurrently. That prompts the need to develop a solution, based on the state-of-the-art IT technologies, to enable us to solve the problems associated with foundry production planning. The paper outlines a methodology of creating the simulation model of a virtual foundry, as a tool for foundry design. An integrative approach is suggested for development of a complete foundry model, enabling the design of more efficient production systems. The underlying principles of such models are discussed, the basic stages involved in the methodology are outlined and the range of its applicability is defined.Keywords: Virtual foundry, Modeling, SimulationSystemowe podejście do projektowania bądź rekonstrukcji systemów wytwarzania wymaga równoległego rozpatrywania zagadnień technologicznych, technicznych, organizacyjnych i ekonomicznych. Stwarza to potrzebę opracowania rozwiązania, opartego na najnowszych osiągnięciach technologii informatycznych, pozwalającego na kompleksowe rozwiązywanie problemu projektowania systemów produkcji odlewniczej. W pracy przedstawiono metodykę tworzenia (budowy) modelu symulacyjnego tzw. wirtualnej odlewni jako narzędzia projektowania zakładu odlewniczego. Zaproponowano iteracyjne podejście tworzenia kompleksowego modelu odlewni, dające w efekcie możliwość projektowania bardziej wydajnych systemów wytwórczych. Przedstawiono zasady konstrukcji takiego modelu, opisano podstawowe etapy metodyki oraz określono możliwości jej zastosowania.

Applications of Monitoring of Electric Power Parameters to Performance Evaluation of a Model Vacuum-Assisted Moulding Installation

“…These components are connected with a pipe installation and ball valves WKK4a, forming a spatial structure of three chambers having the respective volumes V1=4.75 dm 3 , V2=9.42 dm 3 and V 3 =14.17 dm 3 (sum of V1 and V2). This configuration allows for extending the scope of the experimental program, so the influence of the chamber volume on the compaction performance can be investigated without expanding the test stand (Fig 5) [14,15].

“…Data are sampled at the frequency 300 Hz for each transducer system. The recorder has a number of extensions and seats to enable the remote-control activation of the recording process and real-time data transmission to the computer via the RS232 and USB ports, at variable speed of data transfer [14,15].…”

Influence of the reclamation method of spent moulding sands on the possibility of creating favourable conditions for gases flow in a mould

“…The successive important element, within the considered aspect, especially when the moulding sand with the organic binder is used, is its gas volume emission rate (dependent on the resin quantitative fraction in the moulding sand [10]), influencing the rate and possibility of carrying away of gases from the mould. Manufacturer predicted to create a virtual model of a foundry in order to analysis flows of reclamation sand [11].…”
