Cutting tools testing and additive material modification

Research group leader: doc. Ing. Josef Sedlák, Ph.D.

Research group description
The research group is focused on solving the problem of testing the cutting performance of machine tools, during which materials are removed by the cutting edge of a cutting tool with a defined cutting edge geometry, whose potential falls mainly in the field of engineering industry. The research group is also involved in the design and manufacture of prototype cutting tools using 3D printing technology, various CAx applications and related manufacturing processes. The group's activities are key to the development of these areas and include the following activities: the group tests the cutting performance of cutting tools, their wear, durability and service life, and the machinability of the material, all with regard to the resulting surface integrity. In particular, the aim is to map the cutting process when machining the desired material, focusing on the force load during the machining process, the energy consumption of the cutting process, the wear of the cutting tool cutting edges, the resulting durability and surface integrity. The research group works with companies to solve specific problems, develop new technology requirements and related technology developments. The outputs are designed and implemented with the aim of rapid introduction into commercial and industrial use. The research group also focuses on publishing activities addressing current issues and presenting its results at professional conferences and scientific journals, thus contributing to the development of the field. The research group deals with requirements in the field of development of cutting tools, mainly in the field of economic cooperation. In the field of cutting tool testing, the research group has solved and is currently solving several requirements within the framework of economic cooperation or within the framework of the OP TAK calls of the Ministry of Industry and Trade of the Czech Republic. The aim of this collaboration is in particular to design and implement a measurement methodology to address a specific requirement with results that will contribute to the promotion of an innovative technological approach and related outputs into practice. The research group cooperates with specialists from the University of Defence in Brno, University of Mining in Ostrava, Tomas Bata University in Zlín, Alexander Dubček University in Trenčín, University of Žilina and other organisations, whereby the cooperation enables sharing of the issues addressed and thus mutual synergy.

High precision machining

Research group leader: doc. Ing. Karel Kouřil, Ph.D.

Research group description
The field of High Precision Machining Research is concerned with the research and development of tools and technologies, with a particular focus on cutting. The objective is to achieve high dimensional shape and positional accuracy requirements, while simultaneously maintaining high quality and functionality of the machined surface, or surface integrity. Research and development is concentrated on the cutting tool, its geometry and microgeometry, the cutting material, and the coating. A further area of importance is the appropriate choice of cutting conditions, workholding and, in particular, the type and parameters of the machine tool. The outputs in the form of prototype tools and technology ensure efficient production of high-precision and quality workpieces.

Composite materials and technologies

Research group leader: Ing. Jan Zouhar, Ph.D.

Research group description
The group is dedicated to the application and research of composite manufacturing technologies with a focus on ballistic protection and natural fibre applications. The research is motivated by the strategy of reducing the carbon footprint and using natural renewable resources for applications that are not strength driven and where there is a suitable weight saving with little economic impact. Currently, the group is engaged in innovative projects with automotive and UAV flight vehicle companies. Furthermore, developments are focusing on manufacturing technologies, in particular processing and moisture protection, which is a determining limiting factor in terms of the applicability of natural fibre composites. Currently, no detailed research is being carried out directly in this area in the Czech Republic. Instead, researchers are in contact with institutes that deal with partial tasks, including TU Liberec, UTB Zlín, and CTU. The objective of the research facility is to develop viable combinations of resins, fibres and their processing technology for the aerospace and transport industry.

Materials behaviour at high strain rates

Research group leader: Ing. Miroslav Jopek, Ph.D.

Research group description
The High Strain Rate Laboratory is a state-of-the-art research centre specialising in the study of material behaviour under dynamic loading conditions. We study materials under compressive, tensile, shear and torsional conditions, as well as combinations of all of the above stresses up to a strain rate of 10⁵ s⁻¹. For this purpose we use state-of-the-art experimental equipment, such as Taylor test (TAT, STAT), Hopkinson test (SHPBT, SHTBT), acoustic gun, drop tower test not only at room temperature but also at raised or reduced temperature (-80 ÷ 950 °C). For the evaluation of dynamic tests we use highly sophisticated equipment such as a high-speed camera with a maximum frame rate of 1.1-10⁶ FPS, piezoelectric dynamometers, strain gauges, capacitive sensors and oscilloscopes with very fast memory recording, which allow us to monitor and analyze these fast processes using DIC. In addition, we can evaluate microstructural changes in the material using light microscopy, measure and analyze microhardness, and capture shapes using digitally scanned image analysis. The center is also equipped with highly sophisticated computing technology to numerically simulate high-speed processes in programs such as ANSYS. The Centre's research activities have a wide range of applications in various fields from the automotive, aerospace, military, food and forestry industries to the circular economy. We work with major industrial partners and international research institutions to bring new insights and innovations that can lead to improved safety and efficiency of materials in real-world applications. Our team is made up of experts with a wealth of experience who are committed to pushing the boundaries of science and technology. We emphasize an interdisciplinary approach and innovative solutions, enabling us to effectively address complex scientific and technical challenges. The High Strain Rate Laboratory is where theory meets practice and where new technologies of the future are born.

Precision casting on a fusible model

Research group leader: Ing. Vladimír Krutiš, Ph.D.

Research group description
The research group is involved in the research and development of advanced technologies for the aerospace, medical and automotive industries, including components for the energy industry. The focus is on ceramic shell the implementation of additive technologies for so-called hybrid technologies, namely in the field of 3D printing of the model, ceramic cores and filters. Development focuses on the choice and properties of materials used for 3D printing and the resulting quality of the models. A significant part of the activities is devoted to the numerical simulation of precision casting processes, the identification of boundary conditions and the verification of the simulation itself. Research is focused on the composition and properties of ceramic suspensions and sprinkles. The processes of interaction of cast metals with refractory materials, the effects of surface treatment of ceramic cores on wetting angles and on surface tension are studied. Process effects in the manufacture of ceramic shells on strength, permeability and cracking in the mould and in the castings are investigated. Research is also directed towards the casting of special high value-added materials such as superalloys, HEA alloys or Ti-based alloys. The working group is also involved in the training of practitioners and has established a co-operation with the EICF by organising an international course entitled EICF INVESTMENT CASTING MANUFACTURING TECHNOLOGY COURSE.
