Long-term professional orientation
The group focuses on maximum exploitation of modern production machines belonging to the sector of Machine Tools. This sector includes “maternal” production machines, such as machine tools, forming machines and newly also machines for additive manufacturing (AM) and hybrid manufacturing (HM). Our area of interest also includes related local automation of machines and their connection to other machines and higher manufacturing units. Machine tool maximum exploitation can be significantly influenced by optimizing manufacturing technology, process parameters, control setup and basic technology demands.
Maximum and targeted optimum exploitation of modern production machines and technologies is the key to efficient manufacturing of the future. The production machine and the technology used (machining, forming, additive) make up the basis of manufacturing instruments. The machine and the technology applied are the cornerstones of manufacturing cells, flexible manufacturing systems and entire manufacturing plants.
We focus on the following three roles of the machine:
- An efficient machine with a technology that minimizes time, material and energy demands to achieve accurate and high-quality production;
- A machine with technology and automation as an essential element for optimum planning of entire manufacturing systems;
- A machine and technology as part of modern manufacturing within the Industry 4.0 concept with bidirectional communication, adaptive control and information sharing with other machines.
The group is gradually developing workshop and manufacturing facilities for laboratory purposes of the Czech Institute of Informatics, Robotics and Cybernetics and Czech Technical University faculties.
Current research topics
Výzkumné téma 1: Energeticky a nákladově efektivní technologie obrábění
- Efficient machining technology for difficult-to-cut materials, composite materials and new materials using metal cutting and laser machining with a focus on reducing energy, material and cost demands.
- Efficient machining of complex shaped workpieces using multifunctional machines (combining multiple technologies) aimed at minimization of manufacturing time and energy consumption and maintaining maximum productivity, accuracy and quality. Solutions applicable to all main operations: milling, turning, sawing, drilling and boring.
- Optimizing the exploitation of virtual modelling technologies and virtual machining technologies for all levels of machine and process control (cutting conditions, selection of technology, CAM, postprocessing, feed drive control, CNC, PLC) aimed at enhancing energy efficiency.
Research topic 2: Efficient additive manufacturing
Rychlá výroba strojních dílců z kovů a plastů, hranice efektivní výroby technologiemi AM z kovů, kombinace metod rapid prototyping se sléváním, navařování v kombinaci s obráběním, nové techniky programování strojů pro technologie AM a HM, výzkum možností využití plazmového navařování metodou PTA (plazma Transferred arc) pro vytváření funkčních návarů i pro tvorbu 3D dílců. Analýza a optimalizace procesu kontinuálního navařování a vytváření kovokeramických vrstev.
The research makes use of extensive expertise gained both in national projects (Research Centre of Manufacturing Technology, Centre of Competence – Manufacturing Technology of the Czech Technology Agency of the CR, Alfa projects and Czech Ministry of Industry and Trade projects) and prestigious international projects EC FP7 – NEXT and ECOFIT. The investigation team includes employees of the Department of Production Machines and Equipment, Department of Manufacturing Technology and Department of Machining Technology, Process Planning and Metrology, Faculty of Mechanical Engineering, Czech Technical University in Prague.
In the future we expect the participation of the following university institutes: Department of Designing and Machine Components (designing methods for AM and HM technologies), Department of Environmental Engineering (recuperation methods), Department of Automobiles, Combustion Engines and Rail Vehicles (demanding applications of AM products), Department of Material Engineering (homogeneity and mechanical properties of AM products), Department of Management and Economics (LCA analyses).
