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.

Programming CNC machines with digital control system Fanuc.
Tkáčová, Alena ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
The theme of this bachelor thesis focuses on the CNC-programming, which is currently used in many branches of the machine industry. The theme is elaborated and divided into well-arranged chapters. The first part deals with the development of the control system of cutting machines, beginning with the hard automatization and ending with the computer-controlled cutting machines. In the second part there is described the general control system Fanuc including the machine description. The third part contains the application of the real cutting procedure - with the NC program for turning and milling of the sample component in a certain company.

Design of an engraving LED laser
Kasík, Martin ; Sliwková, Petra (referee) ; Dvořáková, Jana (advisor)
This thesis is focused on the search of unconventional machining methods, especially on the technology of laser beam machining. It deals with the area of laser cutting and engraving and examines the influence of individual technological parameters on the given process. Furthermore, there is proposal of design of hobby LED engraving machine, its supporting structure, HW and other electronic components. The prototype of the device is physically assembled and its functionality is verified in the form of several engraving tests of raster and vector formats of graphic materials, and some several shape cuts are made also. The technical evaluation of the assembled equipment, evaluation of tests performed and cost calculation is part of the work too.

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
