1. 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.

8. 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.

9. 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

11. Use of plasma to generating a modified surface on the steel sheet

    The present state of knowledge at worse formability new coatings on metal, respectively. non-metallic base does not fully utilize the possibilities of the possible composition of the plasma, leading to further expand the limits formability of metal sheet forming operations bending and drawing. The aim of research at the Institute of Manufacturing Technology will be the establishment of process parameters of plasma jet systems for surface treatment of thin sheets for metal forming technology selected to increase the surface quality of parts after bending, pulling and reaching higher limits formability, especially for complicated shapes of parts with coatings.There is cooperation and other university laboratories, both in research and verification of new knowledge. To date published research findings at home and abroad are very limited in relation to the sheets, or they are generally conceived to macromolecular substances. The theme continues the program Competence Centers TAČR. Centre researches finishes no. TE 02000011 (year 2014).
