Issued topics of Doctoral Study Program

  1. Analysis of surface and subsurface layers after wire electrical discharge machining

    The dissertation is focused mainly on the analysis of the wire electrical discharge machining process, primarily in order to map dependencies between the machining parameters and the resulting quality of surface and subsurface layer.

    Tutor: Mouralová Kateřina, Ing., Ph.D.

  2. Application of modern technologies for production of complex shape surfaces

    Research and development of technologies for special-purpose shell components which could be used as bone replacement or implants. The aim of research is to propose a technology of prototypes creation with support of reverse engineering, rapid prototyping and CAD/CAM. Technology could be potentially applied in orthopaedics and surgery for special trauma cases. Significant contribution of this research may lie in a lesser incision into patient body, reduction of femur bone cutting, considerable preservation of own bone material and reduction of the time and costs in the operation.

  3. Application of single-point forming at CNC machines.

    Single-point forming is a production technology, which uses diagrams of limit formability of materials, simple forming tools and CNC machines to produce parts or prototypes using point to point forming. This procedure can get a fully functional prototypes made of metals. The aim is to analyze the formability of a selected material, make a CNC technological programme and experimental verification of the production technology.

    Tutor: Píška Miroslav, prof. Ing., CSc.

  4. Progressive technologies of five axes machining at machining centres

    Modern technologies of 5-axis machining are very frequently asked machining operations at modern CNC centres. 5-axis machining has been used in aerospace applications for many years but it is only recently that the toolmaking industry has shown similar interest. The main advantage of 5-axis machining is the ability to save time by machining complex shapes in a single set-up. Additional benefit comes from allowing the use of shorter cutters that permit more powerful and more accurate machining.

  5. Reaction of duplex steel melts with refractory materials

    During melting of high alloy steels the melt containing elements with high affinity to oxygen is in contact with refractory materials of hearths, crucibles and ladles. From the point of view of physical chemistry they are heterogeneous systems consisting of two phases (liquid and solid) separated with a phase interface. It can be assumed that in most cases the system in its initial state is out of balance, while achieving a balance is a natural tendency realized with a number of processes ongoing spontaneously. As a result of it in the melt – refractory material phase interface the atoms of components between adjacent phases are exchanged often accompanied by chemical reactions and deterioration of the refractory material. Processes ongoing in the melt – refractory material phase interface significantly influence the molten steel quality. Therefore the purposeful control of production quality of special steels with high use properties requires the knowledge of the principles of processes in the given interface.

  6. Study of the efefects of deformation rate and temperature parameeters on formability of Al alloys

    On selected Al alloys, which are used in the manufacture of components for the chemical, aircraft, and nuclear power industries, the non-uniformities of the distribution of deformations and structural changes shall be assessed, and the effect of increased temperatures and deformation rates on the formability of these alloys shall be evaluated. Constitutive equations for the stress-strain curves will be written as materials models to be used in the calculation models of current software programs

    Tutor: Forejt Milan, prof. Ing., CSc.

  7. The limiting strain of carbon steels in cold bulk forming

    The selected low-carbon steels, which are used for forming the coupling parts volume and machine parts, to assess their plastic and structural changes at high deformations and limit the influence of strain rate. Create a constitutive equation for stress-deformation curves with the limiting conditions limit deformation.

  10. Use of Additive Technology for the Production Concept of Cutting Tool

    Research and development of the design technology of cutting tool that could be used in practice in conventional machining. The aim of the research is to design technology for the prototype cutting tool, with the support of reverse engineering, Rapid Prototyping and CAD/CAM, potentially applied in manufacturing practice after the necessary cuttingability tests connected with force analysis. A significant benefit of this research can be the achievement of a lower economic point of view associated with unlimited possibilities of setting the printing parameters, analyzing the material structures and application of special coatings to the cutting part of the tool.
