Tool changing of vertical turning lathe
Huňka, Radek ; Skýpala, Milan (referee) ; Marek, Jiří (advisor)
This master's thesis deals with the problems of tool changing of vertical turning lathe. Specifically about modular system of spindle locking in a ram. The master's thesis is shows types of structural design, choosing the best design with supporting technical - economics evaluation. After this is realized series of calculation controls. These define dimensions of the mechanical parts.

Design of multi-functional machining centre
Matěja, Josef ; Holub, Michal (referee) ; Blecha, Petr (advisor)
The Diploma thesis deals with the design solution of multi-functional machining centre, especially with one of its parts – the design of the slide ram and vertical feed incl. the choice of convenient tool heads for the slide ram. The introducing part deals with the numerically controlled machines and centres generally, especially with the portal-type ones. It contains description of individual machine parts including examples of accessories from product plans of domestic and foreign producers. The second part of the Diploma thesis contains calculations and design solution of the slide ram and feed including the choice of the most suitable accessories applicable for this purpose. In the final phase the model of the slide ram has been introduced in the imersion virtual reality and integrated in the complete machine design. The Diploma thesis has been elaborated using the relevant technical literature.

Computational analysis of the steel-composite carrier of the machining center TM 2000
Zbožínek, Martin ; Obdržálek, Vít (referee) ; Vrbka, Jan (advisor)
The main objective of the work was to perform a computational analysis of the hybrid (steel-composite) carrier and compare the results with the original metal carrier. Static analysis, modal analysis and frequency response were solved. Computation was performed for three different relative positions of the carrier. Static stiffness, natural frequencies and dynamic compliance have been calculated. The results were verified by an experiment performed on a scaled-down model of the carrier. Modern software products, namely MSC Patran, MD Nastran, Matlab and ProENGINEER, were used for the calculation.

Multifunctional machining centers for machining rotating and prismatic parts
Grätz, Tomáš ; ing.Petr Polišenský, TOSHULIN,a.s. (referee) ; Marek, Jiří (advisor)
In this master's thesis is elaborated lay-out, calculations and technical drawings to multi-function machining center. Here is applied solution with vertical carousel combined together with the upper gantry milling machine. The aim of my work is to design a compact milling ram allowing turning and milling in deep slots or next to the tall walls of the workpiece. Furthermore here is elaborated lay-out of automatic tool change with magazine and lay-out of clamping exchangeable milling heads. Emphasis is placed on the manufacturability and reliability of the whole structure.
