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. Development of technology for the production of castings from hyperduplex stainless steels

   Stainless steels and castings made of stainless steels have an irreplaceable place in the food, chemical industry, energy, etc. Hyperduplex stainless steels are among the alloys with the highest corrosion resistance. During the solidification of castings from these steels, considerable precipitation of intermetallic phases occurs, which fundamentally affects their plasticity and toughness. As a result, the connection of the castings is broken already during their cooling in the mold. The production of castings from these steels is therefore associated with a high risk of cracking and very limited possibilities for corrective welding. The aim of the work is to design and verify the technology of production of castings from hyperduplex stainless steels, which will include in particular the verification of the influence of the cooling rate of castings on their structure, microstructure and mechanical properties.

2. Research of material and technological properties of abrasion-resistant Hardox sheets

   The dissertation is thematically focused on material and technological research of abrasion-resistant Hardox sheets. Their increased physical and mechanical properties result from the process of rolling at high temperatures and subsequent hardening and tempering, which predestine them for use in a wide range of special applications and drilling rigs as well as special machine mechanisms. Hardox abrasion-resistant sheets are produced by hot rolling at temperatures of 900 to 920 °C, with a cross-section reduction of 50 ÷ 85%, in the area of stable austenite. Subsequently, within 1 min it becomes cloudy in the water shower. This achieves a hardness of 46 ÷ 50 HRC, after low-temperature tempering at 200 to 300 °C. The Hardox material is a structural medium-alloyed high-strength steel heat-treated by controlled rolling. It is characterized by a hard low tempered martensitic structure with a small amount of residual austenite. The reason for the need to carry out such research is undoubtedly the fact that the production of often large-sized components of specific shapes is expensive in all respects and these components are exposed to enormous stress and mechanical wear in processes that have a significant impact on their life. The processes of failure, fatigue and corrosion begin on the surface or just below the surface of the workpiece. Research into the condition of machined surfaces also includes the conditions under which the surface was manufactured and takes into account various technological methods and their effect on the properties of the surface after machining and relates them to the functional requirements of the part. Therefore, more and more research is needed into the essence of creating a new surface and explanation or. expanding the already acquired knowledge about the influence of technological methods on the properties of the newly formed surface. Due to the deformation and thermal effects that accompany the technological processes themselves, internal stresses are formed in the surface layers and the physical-mechanical properties also change. Therefore, research into these problems creates conditions in engineering technology to build new theories and development trends, which will aim to optimize the technological methods used and their impact on the resulting mechanical properties and microstructure of machined surfaces and the subsequent formulation of new relationships between these aspects. The analysis, research and publications of many authors show that each technological operation has an effect on changing the properties of the machined surface and also shows that the influence of individual factors on the functional properties of machined surfaces is not always the same. Without research into all these laws, which determine the condition of the machined surface, it is not possible to solve the problem of quality and functionality of surfaces. The equipment of the partner research center of the Faculty of Special Technology called CEDITEK (Center for Quality Testing and Materials Diagnostics) will also be used to the maximum extent for research.

6. The study of dynamic properties of boring tools

   Dynamic properties of the cutting tool are defining attributes of machining productivity, especially in the case of boring technology, where is applied a long tool with low rigidity and ratio L/D up to 10. The dissertation thesis will focus on research of boring technology and state of art of boring tools design solutions from the perspective of cutting process stability. The experimental part of the dissertation will aim to verify the functionality of selected boring tools with precisely defined extensions and to determine their dynamic behavior. These experiments will use special measuring instruments to diagnose mechanical vibrations. In parallel with the experiments will be performed calculations using simulation software and CAD/CAM application for verification of tested tools mathematical models. The benefit of dissertation will be obtaining practical knowledge for further development of prototype boring tools of new generation and their application in a manufacturing process. The modern approaches will be taken into account for designing and optimizing the geometry of the boring bar using additive metal-based technologies that will ultimately allow increased chatter stability and productivity of the machining process.

Due to the high demands on production productivity and proper mechanical properties, this technology is a very promising choice for prototype component production. The task of the thesis will be to evaluate possible methods of 3D printing of tool steels as an alternative for tools renovation. The next task will be set methodology for testing finished components. The main goal will be to study feasibility and possible practical applications in industry. Attention will be focused on the assessment and optimization of process parameters, weld ability, machinability study of material properties and structures related to the production of individual prototype components.
