Verification of Numerical Simulation Using a 3D Optical System for Measuring Deformations
Zakl, Alexandr ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
This master’s thesis discusses the current state of optical metrology and its place in manufacturing and optimization of parts made by deep-drawing technologies. First part is devoted to building a solid knowledge base in different fields that this thesis draws from. These fields are Optical Metrology, deep drawing of sheet metal and simulations using finite elements method. Subsequently, in the experimental part there are chapters dedicated to Measurement and creation of material models and measurement of grid markings on deep-drawn parts provided by ACO Industries, measured by photogrammetric system from German Company GOM metrology. Additionally, for reference to the measurement, FEM software called PAM-Stamp is used to simulate and predict the final state of the parts after manufacturing. Furthermore, optical metrology was used during creation of material models, data supplied by this analysis was used as an input for the simulations. The last chapter then deals with the evaluation and comparison of measured and simulated data and drawing conclusions about the reliability of optical systems and modern technologies in technical practice.

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.
