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.

The Doctoral Study Programme in Manufacturing Technology is a continuation of the currently accredited master's degree programme in Manufacturing Technology (N-STG), with specializations in Engineering Technology (STG), Engineering Technology and Industrial Management (STG), Modern Lighting Systems (MTS) and Foundry Technology (N-SLE) without specialization.
In the study of Manufacturing Technology, it is possible to specialize in machining technology and its optimization, forming and welding technology, foundry, production control, machine modelling applications, computer aided manufacturing technologies, computer simulations and thus allows to continue in the third stage of study. On the basis of a successful defence and achieving the scientific degree of Ph.D. the graduate demonstrates the ability of scientific work.

1. Advanced technologies for 3D printing of metal parts and their machining

   Today, 3D printing has become a huge phenomenon, involving previously impossible technical applications and now about a number of scientific studies, especially their material properties. These successful applications are significantly affected by the degree of mastery and optimization of self-sintering using beam technologies (laser, electron beam). The influence of the beam inclination, its focusing, line spacing and power on material properties as well as the formation of a number of material defects, accompanied by, among other things, unfavorable tensile residual stress, is already known here. However, it turns out that without machining and advanced finishing operations, these parts have very low fatigue properties to virtually none, which makes their use in the "as built" state virtually impossible in many dynamically loaded systems, despite their high production costs. This work will focus on such applications, which are almost impossible to produce with standard technologies, advanced machining and finishing of functional surfaces for selected applications and their safe use. The topic builds on more than a decade of successful research by IMT in this area, is technically provided and, among other things, it is possible to use BUT instrumentation, but also equipment in Sweden, Germany and Italy as in previous projects and publications.

2. Micromachining of materials by picosecond laser

   Picosecond laser micromachining of materials is a modern advanced technology enabling machining of a wide range of metals, ceramics and plastics with micrometer precision and without thermal effects on the material. This topic assumes the study of the influence of process conditions on the machined material and also the use of technology in the production of specific parts.

3. On the advanced parting technology of steel tubes

   Tube parting is a common manufacturing operation in a number of applications in the engineering industry, where lightweight hollow beams are advantageously used to transmit force loads and minimize the weight of these beams. The main users are the divisions "automotive", but similar applications can be found in the aerospace and civil engineering. A number of techniques can be used to cut these materials, beginning from chipless (shearing) methods, through sawing to grinding, cutting using beam technologies, etc. Each of these methods has its advantages and disadvantages, as well as the use of various process fluids. The work will focus on the division of these pipes by machining. Existing cutting technologies usually use saws (band, circular), but the variability of the chip cross-section causes impact stress on the teeth, their premature breakage and irregularity of the cutting surface, which then makes them difficult to weld outside of other production downtimes. The work will focus on the innovation of machining technology, including a new type of cutting tool, innovated cutting edge geometry, tool, workpiece clamping, optimization of cutting material, its coating, but will also include a new machine tool concept, innovation of its CNC programming and in one operation. IMT has all the necessary facilities, instrumentations and SW needed to the work.

4. Research of conditions of graphitic expansion during solidification of cast irons and possibilities of its influencing

   During the solidification of graphitic cast irons, carbon is precipitated from supersaturated austenite. Carbon, such as graphite, is precipitated in the melt during solidification, the amount, shape and distribution of which in the matrix have a fundamental influence on the mechanical, technological and physical properties of cast iron. The aim of this work is to investigate the effect of inoculation and modification of cast irons on the course of graphitization and the change in pressure in cast iron during the precipitation of graphite during solidification.

5. 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.

6. Usage of additive technologies for printing complex body replacements using methods of creating layers and coatings

   Thesis will be interested in the options of using additive technologies of 3D printing of metals and other materials for needs of creating complex joints replacements. Due to combination of 3D scanning followed by using of additive technologies of 3D print, it is possible to effectively prepare a joint or other body replacement that completely respond to the patient's size and shape. There is expected print primary from biocompatible materials with subsequent use of surface modification, one of the examples is deposition of various types of coatings. The aim of work will be preparation of technology with suitable combination of additively printed material with subsequent deposited coating.
