The doctoral study programme in Manufacturing Technology is focused on production sciences and technologies, namely machining, forming, welding, foundry technology, surface treatment technology, including automation of production preparation and automation of production processes that use and require these technologies.
During the study, students will gain knowledge of applied mathematics, physical metallurgy, experimental theory and optimization of technological processes, along with other theoretical and practical knowledge closely related to the selected area of doctoral study.
The aim of the doctoral study programme is to prepare highly qualified staff for scientific work in the field of engineering technology. The study is focused on the knowledge of the theoretical basis of the whole field and also on a detailed acquaintance with the most important findings in a narrower focus, which are followed by the topics of the dissertation. The study is focused on preparation for scientific work in the chosen field and the achieved level of knowledge is presented at the state doctoral examination.
The ability to achieve original scientific results is demonstrated by the elaboration and defence of the dissertation. After a successful defence of the dissertation, the graduates of the doctoral study programme are awarded the academic title "Doctor" (abbreviated to Ph.D. after the name).

In the doctoral study of the Manufacturing Technology programme, it is possible to specialize in the field of machining technology and its optimization, forming and welding technology, foundry technology, production management, machine modelling applications and computer simulations. Doctoral students are able to participate in all forms of research, contract development and economic cooperation with industrial companies, where they solve advanced problems of technical practice. They also have the opportunity to take advantage of short-term and long-term internships and study stays in our country and within the EU in cooperation with foreign universities.
Graduates of the doctoral study program Engineering Technology have comprehensive professional skills and knowledge of production technologies, methods of their management and planning, have knowledge in the field of materials science and engineering in application to selected production technologies, both theoretical and practical.
Graduates of the doctoral study programme in Manufacturing Technology are expected to be employed in leading positions associated with the technical and technological preparation of production, its management and further development.
Graduates will also be employed as research and development staff in applied research centres as well as academic staff at universities and academic institutions.

Graduates of doctoral studies are equipped with very good theoretical and professional knowledge and therefore have a wide range of employment opportunities in professional or management positions within state and private engineering or interdisciplinary manufacturing companies, from small and medium-sized companies to large joint stock companies. The acquired knowledge can also be used as research and development workers or private entrepreneurs in our country and abroad.

1. Analysis of the wear mechanisms of circular saws and the increase of their cutting performance.

   Circular saws have long been an indispensable cutting tool with a stable position in basic production technologies. At present, they are modernized mainly by changing geometry, application of powder metallurgy for the cutting part of the tool, heat treatment, and application of hard and abrasion-resistant coatings. The basic goal of this work is to design a modern cutting tool for cutting structural steels by machine cutting. The study can be supported financially by cooperation with an industrial enterprise, but also conditional on later binding employment in this company.

3. Design of a methodology for testing cutting tools for advanced materials used for interdisciplinary applications

   The topic of the thesis will be oriented on the design of cutting test methodology of innovative cutting tools, their implementation and analysis of the cutting process, which will be focused on finding the required properties according to machining operations. The research will cover the evaluation of cutting tool wear, surface quality analysis and other available parameters that will be the basis for the selection of practical applications.

4. Geometry of finishing tools and its effect on the integrity of the machined surface

   Very high requirements for operational reliability and durability are placed on products, especially in the field of the automotive industry, hydraulic components, aviation, etc. The useful properties of the components depend mainly on their construction, the selected material, the quality of production, but also on the selected production technology and working conditions, workload, quality of maintenance, etc. The geometry of the cutting part of the tool creates, under the selected working conditions, a newly machined surface with specific properties, which can be described by a set of mechanical, physical, chemical and dimensional quantities, which we collectively refer to as surface integrity. If the appropriate surface integrity is defined for a specific component with regard to its function, reliability, durability, the task is to design such a cutting tool and working conditions to achieve the desired integrity.

5. Joining of hardenable Al alloys for maximum mechanical properties

   In view of the weight reduction of ground vehicles, hardenable Al alloys are also being massively used for components subjected to high static, dynamic and fatigue loads. In the integral strength of the stressed assembly, welded joints are considered as a weak point, because the weld causes a reduction in the strength of these alloys, thus limiting their use. The aim of this work is to compare and find a suitable technology for joining parts made of Al hardenable alloys with respect to the highest possible mechanical properties, including fatigue. Al hardenable alloy sheets will be welded by MIG/TIG, laser and friction stir welding (FSW), or alternatively by bonding, and all necessary quality and mechanical tests will be performed. Process and technological optimisation is envisaged to achieve maximum mechanical properties. The result of the work is to be a comprehensive evaluation of the joining methods with respect to strength, but also the complexity of the process.

6. PVD coatings on axial tools and their effect on useful properties

   Topic content: In many cases, the cutting parts of chip machining tools are provided with coatings that provide them with better useful properties. The very rapid development of new types of coatings is especially in the field of PVD (Physical Vapor Deposition) technology. New trends relate to the composition of coatings, their structure, and the method of application. Special attention is currently being paid to the preparation of the edges before coating. There are a number of edge treatment methods, the main ones include wet and dry sandblasting, tumbling, polishing, etc. New coatings and edge treatment methods provide an opportunity to increase the durability and operational reliability of tools. New trends in the mentioned areas and their interaction is a suitable topic for further scientific research and technical development. PVD coatings, together with the microgeometry of tool edges, are a key element in increasing the life and performance of axial tools.

7. Study of dynamic deformation behaviour of materials prepared by alternative manufacturing methods

   The primary focus of the dissertation is on the determination and description of material models, in particular the mechanical behaviour of plastics and wood-based composites at various strain rates from quasi-static to dynamic on TAT and SHBT devices. The description of the material models takes into account not only the influence and sensitivity of the individual materials on the strain rate, but also the effect of temperature on these mechanical properties. Based on the measured data and experiments, the final test specimen of the composite plate - produced by an alternative method - will also be tested for mechanical properties and compared with numerical simulations.
