Measuring cycles in control systems of CNC machines
Hamřík, Jiří ; Jaroš, Aleš (referee) ; Gregor, Lukáš (advisor)
In the first two points, the bachelor's thesis focuses on the comparison of CNC and NC machines and methods of control and programming of CNC machines, a description of the control system of CNC machines from selected producers and the characteristics of measuring cycles. Two producers were selected to describe the technology of measuring tools and workpieces using probes. In the third point of the bachelor's thesis, a practical demonstration of measurements with tool and workpiece probes from RENISHAW is performed. A tool correction was performed followed by measurement of the workpiece with a probe. For statistical evaluation, digital micrometer measurements were added, including comparison and evaluation of the obtained results.

Implementation of the VERICUT System into the Technological Process of Production
Gerbel, Jakub ; Fiala, Zdeněk (referee) ; Slaný, Martin (advisor)
The topic of this bachelor thesis is implementation of the VERICUT verification system into the manufacturing process in cooperation with company JHV Engineering. Based on the theoretical analysis is performed practical part. The 3D model of the CNC machining center was modeled in system Creo Parametric and its kinematic were compiled in the environment of VERICUT system. After evaluation the results, it turned out that there are some deviations between the simulation and the real process. By creating such an exact virtual copy of the machine, or digital twin, collisions can eliminated and production can be planned more efficiently
