Stanovení nejistoty měření nano-CMM / Determination of measurement uncertainty nano-CMM

Brlica, Pavel January 2018 (has links)
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.

Návrh vhodného etalonu délky pro oblast nanometrologie na pracovištích ČMI Brno a CEITEC Brno / Design of a suitable length standard for nanometology at the CMI Brno and CEITEC Brno

Češek, Jakub January 2019 (has links)
The thesis deals with the design of a suitable length standard for nanometrology. This length standard will be used for metrological traceability of the Rigaku nano3DX located at CEITEC Brno and the SIOS NMM-1 device which is located at ČMI Brno. The first part is focused on the description of these measuring instruments, the analysis of their metrological traceability requirements and the requirements for the material length standard. The second part is devoted to the concrete possibilities of the etalon design, 3D printing of the prototype of the standard and verification of its dimensional compatibility. At the end of the thesis, the evaluation and selection of the appropriate standard design is made.

Návrh vhodného etalonu délky pro nano-CT měřicí přístroj / Design of a suitable length standard for nanp-CT measuring device

Kožiol, Martin January 2020 (has links)
The diploma thesis deals with the design of three length standards, which will serve to ensure metrological traceability between Rigaku nano3DX, SIOS NMM-1, Zeiss UPMC Carat 850 and other devices located at ÚVSSR BUT and CEITEC Brno. The first part of the thesis focuses on the theoretical acquaintance with concepts closely related to the issue of ensuring metrological traceability. In addition, this section deals with computed tomography and the description of individual devices. The second part of the thesis is devoted to design, production process and testing of individual standards. The last part describes the ensuring the calibration of the smallest standard, the so-called Nano standard and the calculation of the uncertainty of measuring its calibrated length. At the end of the thesis, the outputs of these activities are evaluated.
