Data processing from measurement on machine tools
Pokorný, Zdeněk ; Vetiška, Jan (referee) ; Holub, Michal (advisor)
The Master’s thesis deals with the precision of machine tools, especially with the three-axis vertical milling machine. It is structurally divided into a theoretical and practical part. While the theoretical part focuses on problems of geometric errors and measuring devices, the practical one is devoted to the machine tool being tested. In this case, the data processing and the proposed statistical analysis are essential, and at the end of the thesis another possible way of developing the data processing is outlined.

Design of digital twinn of CNC machine tool
Staněk, Václav ; Vetiška, Jan (referee) ; Holub, Michal (advisor)
The Master’s thesis deals with design of digital twins of machine tools and application of designed procedure on a case study – digital twin of the machine tool MCV 754 Quick. In the first part are described current roles of digital twins in the field of machine tools and also hardware and software options for creating them. Software and hardware tools by Siemens (Mechatronics Concept Designer and SIMIT) are used for the case study. The complex procedure of creating the digital twin is designed in the second part, starting with preparation of a model, ending with the virtual commissioning of the machine tool MCV 754 Quick. The procedure is described in detail, including preparation of 3D model of the machine tool, assignment of physical properties and joints, preparation of PLC, connection all the elements of the whole system: Sinumerik – SIMIT – Mechatronics Concept Designer and controlling the twin via CNC automation system. Output of the thesis is the virtually commissioned machine tool, capable of being controlled by Sinumerik 840D sl. This is the first step in development of the full-fledged digital twin of machine tool, which can be used for testing the functionality and capability of this new technology in industry.

Simulation of CNC machine tool spindle in ADAMS software
Pham, Jakub ; Holub, Michal (referee) ; Tůma, Jiří (advisor)
The bachelor thesis deals with the design of a simulation model of a CNC machine tool in MSC ADAMS software. Nowadays, simulations have become an integral part of every development process, as they offer a cost-effective alternative to classical machine development involving prototyping. Within machine tools, dynamic simulation of machine nodes is one of the unexplored areas. The aim of this work is to verify their functionality and reliability in this area. Within the scope of the bachelor thesis, a research on dynamic system simulations, the finite element method and the simulation software MSC Adams and Ansys has been carried out. In the practical part, the spindle loading of the MCV 754 Quick machine tool was designed. Subsequently, the model geometry and boundary conditions were determined and the spindle was simulated during the cutting process in MSC ADAMS. The simulation results were verified by both analytical calculation and experimental measurements on the machine. Furthermore, the concept of further development of the model within the framework of cosimulation was presented. Finally, all output parameters were compared and evaluated.
