Design of cartridge spindle for turning machines
Žádník, Lubomír ; Tůma, Jiří (referee) ; Pavlík, Jan (advisor)
The diploma thesis deals with the design of a built-in headstock of a turning center. The aim of the work is the design of a spindle for machines up to 10 kW. The spindle is driven by a two-speed gearbox and a belt drive. In the introduction, the work deals with the description of individual parts of the turning headstock. A design proposal is performed, accompanied by a number of technical calculations. The result of the work is a 3D model, drawing documentation and calculation report.

3D FDM printer with built-in feeder of filament
Puchta, Daniel ; Huzlík, Rostislav (referee) ; Pavlík, Jan (advisor)
This thesis deals with mechanical design of FDM 3D printer with a built-in material feeder with monitoring of remaining material. The aim of this thesis is designing the FDM 3D printer with minimum print volume of 200x200x200 mm and with usage of measured data for optimising the 3D printing process. This 3D printer is targeted to the non-experienced users, so the emphasis was on ease of use and reliability of the printer. Despite the fact that it is an innovative design solution, the suitability of the design was verified experimentally as part of this thesis. The choice of the material feeder design, which is essential for the presented thesis, was justified by the realization of prototypes of two suitable designs, from which the optimal solution was chosen. The knowledge obtained from testing the prototypes was then used for the final design of 3D printer. The usage of data for optimization of the printing process is realized by a C++ compatible source code that is a part of this thesis.

Design of spindle turning center
Krajča, Martin ; Knoflíček, Radek (referee) ; Pavlík, Jan (advisor)
This master´s thesis deals with the design of the headstock of a turning center. The aim of the work is the design solution of turning headstock with output of about 5 kW with the possibility of positioning in the C axis. The introductory part of this thesis is focused on the descripti-on of the basic parameters of the headstock and turning centers on the market. The next part deals with choice of cutting conditions and calculation of spindle parameters. These calculations are verified using the FEM method. Based on the calculations and design requirements, a headstock model with drawing documentation is created.

Design of spindlespeeder
Závada, Otakar ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This bachelor thesis deals with conceptual design of high speed spindle based on cutting conditions. Research part of thesis describe each types of high speed spindle based of their drive. Next chapter are documented cutting conditions which are corresponded with experience. High speed spindle faced these act most of the time. Cutting conditions show output conditions of planetary gearbox which is described in next part of thesis. All the experience are used in conceptual design. The drawings contains of assambly drawing and drawing of selected components. The drawings are based on model made in 3D CAD system
