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.

See applicable regulations, DEAN’S GUIDELINE Rules for the organization of studies at FME (supplement to BUT Study and Examination Rules)

The rules and conditions of study programmes are determined by:
BUT STUDY AND EXAMINATION RULES
BUT STUDY PROGRAMME STANDARDS,
STUDY AND EXAMINATION RULES of Brno University of Technology (USING "ECTS"),
DEAN’S GUIDELINE Rules for the organization of studies at FME (supplement to BUT Study and Examination Rules)
DEAN´S GUIDELINE Rules of Procedure of Doctoral Board of FME Study Programmes
Students in doctoral programmes do not follow the credit system. The grades “Passed” and “Failed” are used to grade examinations, doctoral state examination is graded “Passed” or “Failed”.

Brno University of Technology acknowledges the need for equal access to higher education. There is no direct or indirect discrimination during the admission procedure or the study period. Students with specific educational needs (learning disabilities, physical and sensory handicap, chronic somatic diseases, autism spectrum disorders, impaired communication abilities, mental illness) can find help and counselling at Lifelong Learning Institute of Brno University of Technology. This issue is dealt with in detail in Rector's Guideline No. 11/2017 "Applicants and Students with Specific Needs at BUT". Furthermore, in Rector's Guideline No 71/2017 "Accommodation and Social Scholarship“ students can find information on a system of social scholarships.

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. Effect of solidification rate on chemical and structural heterogeneity of metal samples

   To analyze the chemical composition of metal samples, spark optical emission analyzers are often used, which need regular calibration for accurate measurements. This calibration consists of setting a curve (straight line) for each element based on standards of known chemical composition. The standards have a precisely defined chemical composition, which must be very homogeneous within the entire volume of the sample. The dissertation itself is focused on the production of these standards using casting technology. The aim of the work is to determine the connection between the conditions of solidification of the material of these standards and their chemical and structural homogeneity. Based on this, suitable production conditions for casting these standards can be defined depending on the degree of their chemical heterogeneity for the given quality standards.

2. Parting of spring steel wires

   A strong pressure on manufacturers in the engineering industry to save energy, reduce the weight of parts and production costs while maintaining or increasing the operational safety of these machine units can be seen in the last years. This trend is particularly evident in transport technology, where the application of materials able to meet these requirements, such as heat treated spring steels, is being systematically addressed. Among other things in connection with the application of more powerful vehicles, there is even a growing demand for parts of larger dimensions and higher strength, the production of which requires special technical equipment for their division. The work will deal with the current state of this technology and the possibilities of its innovation.

3. The use of modern laser technologies to increase the fatigue life of ball pins

   Ball joints are important structural elements of the chassis of passenger cars. The most critical component of the joint is a ball pin. The fatigue strength of the ball pin is a key mechanical property which ensures that the car stays under control and the driver is not in danger. Currently, when a higher fatigue strength is required, an induction hardening is used in the production technology. But this method has a lot of disadvantages. One of the ways to improve the production process is the use of modern laser technologies which allow a local surface treatment. The goal of the thesis is to study the possibilities of using laser hardening technology and highly advanced laser shock peening (LSP) technology to achieve required fatigue strength of the given type of components. The work will be focused on a theoretical analysis of both technologies with respect to residual stresses and their effect on surface hardness and cyclic fatigue resistance of the ball pin in the first phase. The second phase will be focused on experimental research to understand the possibilities of the mentioned technologies and their subsequent optimization leading to achieve the fatigue strength requirements. The laser shock peening will be investigated in cooperation with a research and development centre HiLase.
