Programming of measurement operations through Zeiss Calypso software
 Machara, Marcel ; Šrámek, Jan (oponent) ; Polzer, Aleš (vedoucí práce)
This diploma thesis deals with the issue of measurement on 3D coordinate measuring machines and the related programming of measurement operations in Calypso software from ZEISS. The first part of the thesis deals with the ISO GPS system. The second part of the thesis deals with coordinate measuring machines and basic principles of programming measuring operations. The practical part of the thesis is focused on creating a program for measuring the test workpiece of HSC milling machines. In this part, the basic technical documentation is developed and the workpiece measurement program is created. After the measurement on the 3D coordinate machine ZEISS ECLIPSE 1000, the measured values are processed and evaluated. Within the selected characteristics of the workpiece, the statistical evaluation of the measured values is shown together with the assessment of conformity with the specification according to the standard ČSN EN ISO 14253-1:2023.

Topological optimization of a crane jib
 Machara, Marcel ; Pokorný, Přemysl (oponent) ; Zeizinger, Lukáš (vedoucí práce)
This bachelor's thesis deals with the issue of topology optimization in the design of structures and machine parts. The first part of the thesis consists of a theoretical summary of the current state of knowledge of crane jibs and their basic categorization. The second part consists of theoretical knowledge about optimization problems and the method of topology optimization. In the third part, an example of the implementation of topology optimization on a cantilever crane is processed using the Ansys Workbench software. The parameters of optimized jib designs are compared with the parameters of their basic models. At the end of this chapter, an evaluation of the results of topology optimization is performed.
