Today's dynamic market places new demands on manufacturers, with regard to the continuous and rapid response to market changes and more frequent replacing older products with new ones. Producers looking for new solutions that meet the requirements related to the possibility of further production, without incurring even more manufacturing costs. The change in strategy business method gives the possibility to use the so-called Virtual Manufacturing Network (VMN), which may be the answer to these problems, production in the shortest possible time and at limited cost. This paper proposes a method to help the process of planning the production flow in Virtual Manufacturing Networks to assist solving problems related to the process of alternative routes selection in the network.

An effective optimization process carried out in industrial conditions requires multiple actions in many different areas and the dynamic nature of the manufacturing system and its environment enforce its constant repetition. The paper presents selected techniques for increasing production flow efficiency that can be regarded as a first step of production flow optimization. The considered model was built on the basis of a real production system of mechanical industry, located in Silesia, Poland. A number of improvement actions was proposes, among which the most significant are: elimination of unused and slightly loaded resources, changing transportation lots between workstations, strengthening bottlenecks and optimization of a schedule. In the study the KBRS scheduling system [10] as a tool for solve complex scheduling problems and supporting particular simulations was used. In the result of carried out activities the significant improvements of the production schedule was achieved, in comparison to initial schedule.

This paper describes case study of application of OPC technology in the Laboratory of Integrated Manufacturing Systems, equipped with various industrial controllers, in order to acquire data for exemplary client application using this data. Communication between the automated equipment of the production system allows efficient and immediate acquisition of data on the state of adjoining equipment and production orders, which are the main postulate of Industry 4.0 methodology. Because of the variety of hardware and software in production systems, it seems necessary to use a standard method of communication, such as OPC, allowing client applications to acquire data in a standardized form. Article presents description of configuration of different laboratory stations controlled by PLCs, development of PLC applications, configuration of OPC server (KEPServerEX) with hardware drivers, testing of communication, and finally, example of usage of acquired data in OPC client application - HMI/SCADA iFIX.

The proper warehouse management strongly affects the condition of the company. The paper describes a way to reorganize the input storage layout of steel raw materials of the company that specializes in manufacturing large-size products. In particular, the existing state of the store and next three new conceptions were presented. Attention was paid to the storage area intended for the steel sheets. Some alternative variants of horizontal and vertical steel sheets storing and means of the internal transport were considered in these new solutions. The most important criteria for choosing a solution for implementation were also presented. The designed layout of the magazine, compared to the existing state, enables the elimination of waste associated with the available capacity, reduce time and cost associated with the involvement of the means of production and human resources.

This paper presents the possible application of GRIP NC programming language in order to optimise a manufacturing process. The possible optimization could be provided in Siemens NX Software with use of .Net programing language, SNAP libraries or GRIP NC language supported up to current version. Simplicity of use is a main advantage especially in situation when industrial company starts applying automated optimization in a technological process preparation. Automation should be considered also in order to manage with multi machine processes. In the proposed solution there is an algorithm that executes the loop until parameters, trajectory and strategy of cutting satisfy the set ranges. The software application could be extended for other types of manufacturing. Simultaneously the result of manufacturing process is important according to quality of surface, and chip removal process.

In this paper alternative methods of the artificial lures manufacturing are presented. Proposed approach is based on application of various contemporary techniques it is reverse engineering rapid prototyping and manufacturing and middle-end CAD modeler. It is proposed to use reverse engineering not only for gathering of existing parts 3D geometry but also for acquiring it just from fish. Moreover if there is a possibility to gather information about fish skin texture, with high end 3D scanners, the real-looking fishing lures would be produced. These scanned models are usually sufficiently good for production with rapid prototyping apparatus. In order to meet a client needs application of the middle-end CAD modeler – Inventor is proposed. It allows modeling a product geometry which is well matched to a client needs and requirements. Finally vacuum casting rapid manufacturing method for a small batch production of soft fishing lures is suggested. This paper gives an application example of each above mentioned methods

This paper presents the reconstruction process of medical devices designed for prevention of the haemorrhage in the nasal cavity. The DEMED company (the medical parts plant) turned to authors in order to start a scientific project concerning the problem of elements reconstruction in case of lack of technical documentation. The additional problem with original parts resulted from the original parts manufacturing technology – parts were handmade. The economic purpose from DEMED company angle was to increase the production volume thanks to accessibility of greater number of moulds designed and produced on the basis of reconstructed parts geometry. The proposed in the paper solution is based on hybrid model and selected cross-sections transfer into 2D CAD software in order to prepare technical documentation. In the reconstruction process the 3D scanning was used.

W artykule przedstawiono aspekty związane z zagadnieniami integracji technicznego oraz organizacyjnego przygotowania produkcji. Szczególny nacisk położono na zagadnienia związane z problemem technicznego przygotowania produkcji tj. usprawnienia przepływu informacji pomiędzy systemami CAD oraz CAPP. Przedstawiona została otwarta struktura obiektów elementarnych. Struktura ta stanowiła podstawę w procesie przygotowania, a następnie oprogramowania modułu systemu CAD, jako źródła danych dla systemu CAPP. Opracowany moduł przygotowania modelu CAD elementu działa w środowisku systemu NX. Na podstawie opracowanej otwartej struktury obiektów elementarnych opracowana została struktura klas opisujących konstrukcję wytworu, która na etapie programowania obiektowego stanowiła podstawę do opracowania specjalizowanego modułu systemu CAPP tj. modułu przetwarzania danych o konstrukcji modelu opracowanego uprzednio w systemie CAD. W artykule przedstawiono również strukturę systemu CAPP wspomagającego technologiczne przygotowanie produkcji w zakresie komputerowego wspomagania projektowania procesów technologicznych elementów obrotowo-symetrycznych. Wyniki działania opracowanego systemu CAPP stanowią informację wejściową dla systemu wspomagania harmonogramowania i reharmonogramowania produkcji, który przedstawiony został w ramach odrębnego artykułu, zamieszczonego w ramach bieżącego numeru czasopisma Inżynieria Maszyn.
