Laboratories.
Due to the complex field of expertise, Department has 5 laboratories that are used for education, scientific and research activities, as well as for cooperation with the economy.
The following laboratories (of the Department) are used for education purposes, scientific-research work and cooperation with the economy:
- Laboratory for ERP systems and TCR (Tele-Conference Room)
- Laboratory for System Modelling and Process Control
- Laboratory for Computer Aided Process Planning (CAPP) and Computer Aided Design (CAD)
- Laboratory for Computer Integrated Manufacturing (CIM) and Maintenance
- Laboratory for Rapid Prototyping
Laboratory for ERP systems and TCR is used for development of ERP (Enterprise Resource Planning) system, for upgrading certain modules through implementation of mathematical models and models based on artificial intelligence defined during researches in the production companies. Interactive video conferences are used for cooperation with other institutions.
Tele-Conference Room (TCR) is used for:
- Lectures
- video conferences, where a large group of people can watch a lecture (held at some other location). This includes lectures for mandatory courses, as well as scientific conferences;
- short meetings such as: seminars, conferences, round table talks, presentations, etc.
- meetings that are of considerable interest for the academic community (e.g. educational or scientific purposes).
TCR can be used for holding lectures, video conferences, and other activities when the lecturer or the audience (students, teachers, researchers, etc.) are dislocated, i.e. not present. The lectures can be done in a completely interactive way, with participation of the audience, the possibility of asking questions in both directions, as well as interrupting the lecturer, so that everybody can participate.
The Laboratory for System Modelling and Process Control is used for modelling, design, implementation of conventional and modern systems of control and visualisation of processes. The programming of PLC is done with computer programmes (STEP 7 Professional, IEC 1131-3 of compatible development environment), the tests performed on a simulator and the programmes on the real PLC. Modular SIMATIC PLC concept enables testing of configuration combinations by using distributed periphery and different modules (digital inputs, digital outputs, analog inputs, analog outputs). The students also get to see various measuring probes and their application in combination with PLC. Various possibilities of PLC are shown in this way, which is the basis for creating the control infrastructure on more levels. The students get to programme PLC for solving various technologycontrol tasks. There is also programme support for process visualization – OP (Operational Panel) and PC based SCADA systems (WinCCFlex Advanced). In this way, it is possible to use PLC with textual/graphic control in a variety of combinations that occur in everyday life. There is also the programme support for advanced mathematic modelling and optimization MATLAB which enables studying of basic methods and optimization of structures and processes.
The Laboratory for Computer Aided Process Planning (CAPP) and Computer Aided Design (CAD) deals with modelling in the field of technology and operative process planning.
The Laboratory for Computer Integrated Manufacturing (CIM) and Maintenance deals with maintenance systems, i.e. application of new maintenance strategies (CBM, RCM,TPM,BCM) in order to prolong the work life of the equipment and plants, and to reduce maintenance costs. A special emphasis is put on the implementation of CAD/CAPP/CAM technologies.
The Laboratory for Rapid Prototyping is used for making prototypes in order to shorten the process of design, development and making of the prototype of the new product. Rapid Prototyping (RP) is a production procedure of the first model (of product) that can be used for testing different aspects of its shape and usability. RP procedures shorten the period of time necessary for making the first model of product: while time period for complex products (e.g. cars) was measured in days, months and years, it is reduced to hours and minutes. The most effective RP procedure is 3D Printing. The models in the Laboratory are made on a 3D Printer which is used for rapid prototyping. It is Z310 Printer from Z-Corporation (www.zcorp.com). This was the first device of that kind in Croatia, and this region, according to Mr Carlos Alvarez from the Swiss company MSM Trading AG.
This procedure is used for rapid production of prototypes, but also of finished parts and tools directly from CAD models. The flexibility of 3D printing cannot be compared to other procedures of rapid prototyping. Geometrically most complex parts can be made from almost any material (ceramics, metals, polymers, composites). Such models are used today in many fields.
APPLICATIONS
Department for Industrial Engineering is currently involved in 1 national scientific research projects, funded by the Ministry of Science, Education and Sports of The Republic of Croatia:
Project title: Development of ERP System for Digital Factory
Project coordinator: Professor Tomislav Šarić (Tomislav.Saric@unisb.hr)
RESULTS OBTAINED
The results of the project Development of ERP System for Digital Factory in years 2010/2011:
The research was conducted according to the set schedule of activities. The analysis of special demands in ERP (Enterprise Resource Planning) Systems for various types of production and service enterprises and types of production (metal processing, wood processing and construction) was done. Material Resource Planning (MRP), which is a formal computerized approach to inventory planning, manufacturing scheduling, supplier scheduling and overall corporate planning, was used. Inventory planning for certain types of production, as well as modelling of multilevel component, which will be part of ERP system for different types of production with multilingual application, was done. The analysis of process planning, standardization of technological processes, tools and NC programmes for transfer of technological processes was done. A model for selection of optimal cutting parameters (cutting depth, feed rate, etc.) for the selected machine and type of most widely used materials in the metal processing industry was chosen. The criteria for choosing the most adequate supplier were suggested and analysed. There were two kinds of criteria: commercial criteria (price, delivery deadline, type of payment, meeting the delivery deadlines, complaints) and quality of the delivered goods. Multi-criteria decision making (MCDM) methods were used for choosing the suppliers. A model of basic planning of preparation and production capacities (with expected deadlines and costs according to achieved goals and expected duration) was investigated. The possibilities of defining a Maintenance plan for different equipment (by using different maintenance strategies) were investigated. A model for choosing a maintenance strategy was determined. It is based on Total Productive Maintenance, i.e. a management system for optimizing the productivity of manufacturing equipment through systematic equipment maintenance involving employees at all levels. The research results were published in scientific journals and at conferences.
