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.

Measurement of workpieces on machine tools using a touch probe
Velič, Samuel ; Marek, Tomáš (referee) ; Holub, Michal (advisor)
This diploma thesis deals with the influence of electronic compensation on accuracy of the measurement using the touch probe. The theoretical part concerns touch probes, specifically their classification, principles of working and applications. This part also includes devices used later in the experiment, particularly double ballbar, laser interferometer and LaserTRACER. The Practical part describes an experiment, demonstrating the correlation between the accuracy improvement of the touch probe and the electronic compensation’s level. All measurements were executed in accordance with the norm VDA 5 and were evaluated by the Matlab software. The graphs of reliance tolerance of capability of measurement on the length of the benchmark. At the end of this diploma thesis there are partial conclusions deduced. The deduction is based on generated graphs. The partial conclusions synoptically compare the influence of individual machine´s configurations on the accuracy of the touch probe.

Application of a measuring probes in milling proces on CNC machine MCV1210
Horáček, Kryštof ; Osička, Karel (referee) ; Polzer, Aleš (advisor)
This diploma thesis focuses on the application of measuring probes in the machining process. The main goal of the thesis is to create sample procedures for measuring cycles and functions in a CNC machining process using MCV 1210 and selected measuring software. In the first part of the thesis available methods of machine measurement are outlined with a great emphasis on the description of measurement principles, construction, and measurement signal transmission methods between tool probes and the workpiece. The second part of the thesis deals with the application of measuring probes in the machining of the designed test piece using the Productivity+TM and Sinumerik ShopMill softwares. The work also includes an economic evaluation of the profit of an investment in the mentioned measuring equipment.
