Determination of measurement uncertainty of the optical measuring machine using a laser interferometer
Fulová, Silvia ; Jankových, Róbert (referee) ; Šrámek, Jan (advisor)
This final thesis is dealing with stating uncertainty of optical measuring device Micro-Vu Sol 311, which is located at Faculty of mechanical engineering in Brno. Overview of coordinate measuring machines (CMM for short) and analyzed present status of optical CMM is in summation. This part also includes basic metrology concepts and methodology of determination of uncertainty of measuring instrument. Content of following parts of thesis is detailed description of Micro-Vu SOL 311 machine and etalons that were used in determination of enhanced uncertainty of measurement such as gage blocks, laser interferometer and glass scale. Last part of this thesis includes summary of achieved results and recommendations for practice.

Utilization of surface texture evaluation in revolver production
Kolena, Robert ; Šrámek, Jan (referee) ; Jankových, Róbert (advisor)
This diploma thesis addresses the issue of using the evaluation of surface texture in the manufacture of revolver with aplication to a cock. It deals with the detection of imperfections of production operations, the proposal of corrective measures and its implementation. The use of new grinding wheel was chosen as a corrective measure. The Rzmax parameter was used to specify the surface texture after miling and a combination of the Rzmax and Rpmax parameters was used to specify surface texture after grinding.

Measuring probe tips in engineering metrology
Böhm, Jakub ; Harčarík, Matej (referee) ; Jankových, Róbert (advisor)
This diploma thesis deals with measuring touches problems in industrial metrology. Thesis describes adhesive wear and tear which is caused by measuring probes when dynamical measuring is being concluded. Measuring of damaged component made of silumin and its different changes of texture by different measuring probes are evaluated. Measuring touches are made of titanium nitride, silicon nitride, zirconium, bearing chrome steel, ruby, experimental composite material and nanocrystalline diamond.

Quality assurance of pneumatic cylinders
Pabiška, Martin ; Maradová, Karla (referee) ; Jankových, Róbert (advisor)
This Master thesis deals with the requirements for the quality of ISO standard compliant pneumatic cylinders, which are machined and assembled by a local manufacturer. According to the philosophy of continuous improvement, this thesis describes the project to decrease the number of air leaks detected by automatic testing machines. The main benefits of the thesis are the improvement of the design of pneumatic cylinders and the improvement of their assembly procedure leading to a reduction in the number of air leaks from pneumatic cylinders on automatic test equipment. It also provides an overview and general procedure for selecting, analyzing, implementing measures and taking further opportunities to improve the quality management system of pneumatic cylinders in the company.

Measurement of pitch diameter to length measuring instrument SIP CMI Brno
Malásek, Michal ; Jankových, Róbert (referee) ; Šrámek, Jan (advisor)
This thesis deals with methods for inspection of internal and external threads. One of the aims of the thesis is to give reader insight into the given topic, another one is to improve and simplify process of the thread gauge check at the Czech Metrology Institute (CMI). A database of the thread gauges that are not automatically recognizable by the software used at the CMI will be created. Such thread gauges are still used in practice, but are marked according to the old standards ČSN.

Determination of measurement uncertainty nano-CMM
Brlica, Pavel ; Jankových, Róbert (referee) ; Šrámek, Jan (advisor)
The topic of this master thesis is the issue of measurement uncertainty of nano-CMM, specifically SIOS NMM-1 machine. Theoretical part of the thesis consists of basic measurement uncertainty definitions, description of approaches to CMM measurement uncertainty and differences between classical CMM and nano-CMM. For measurement uncertainty calculation of nano-CMM, two method are chosen and adapted – substitution method and Monte Carlo method. These are applied in practical part for measurement uncertainty calculation of SIOS NMM-1 machine. Part of the practical part is performed measurement on machine in laboratory at the Czech Metrology institute in Brno. The outcome of this thesis is determination of measurement uncertainty of SIOS NMM-1.
