Determination of Material Properties of Specimens Produced by Metallic 3D Printing
Zakl, Alexandr ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
This bachelor's thesis deals with mechanical properties and current status of 3D printing of metal parts, especially by DMLS/SLM method. Research part is dedicated to various technologies and suppliers in the field of 3D printing with emphasis on printing metal methods. Main purpose of this thesis is to connect the worlds of 3D printing and 3D optical measuring of deformation, so the part of research segment is dedicated to optical measuring and leading innovative company GOM. One of the leading product of this company is ARAMIS and in the context of this thesis it was present during the experiment as a instrument for measuring and inspecting material characteristics, and is present in research part where is mentioned a principle on which this device is working (digital image correlation) as is the device itsself. In the experimental part of this thesis, samples were printed on DMLS printer from company XactMetal, which were then submitted to a tensile test. Measurement was done using DIC based device ARAMIS and inspected for basic material properties in same named program.

3D Optical Measuring Systems Suitable for Metal Forming Technologies
Jelínek, Dan ; Štroner, Marek (referee) ; Peterková, Eva (advisor)
The project deals with use of 3D measuring systems operating with non-contact sensors in forming technologies. After the research of means to evaluate formability of materials, there are listed several important distributors of 3D metrology and described some of their measuring systems. Systems that are most usable in forming sphere are ARAMIS and ARGUS developed by German company GOM. These systems are often used for measuring of static and dynamic tests. Specifically for establishing values of major and minor strain, detection of critical areas, optimization of forming processes, measurement of thickness reduction or verification of numerical simulations. They can also depict forming limit diagrams, which can be useful in forming practise. Last part contains evaluation of specific measurement using GOM Correlate software.

Methodology of coordinate system setup for optical measuring device Pontos
Volek, Aleš ; Drápela, Miloslav (referee) ; Koutný, Daniel (advisor)
The graduation thesis deals with invention of detailed definition of the coordinate system for Pontos system. The solution is based on suitable localization method of the point on a car body, whose coordinates are known from CAD data. First part of the thesis describes the design of adapter which determines the reference point. Software solution is presented in second part. Contribution of the work and accuracy of the method are discussed in the end.

Verifikation of machine component strain
Novák, Tomáš ; Dočkal, Aleš (referee) ; Drápela, Miloslav (advisor)
The thesis deals with a comparative analysis of strain of parts using finite element method (FEM) and measurement of the optical system Pontos. Part was used the reflector of Volkswagen Polo. The subject of comparing were the values of deviations optical shield of reflector which excitation random vibration described power spectral density. The thesis presented describes of experimental measurements to obtain the boundary conditions using optical systems. FEM analysis was performed using software ANSYS Workbench 12.
