Design of tool magazine for CNC mill
Sýkora, Michal ; Tůma, Zdeněk (referee) ; Tůma, Jiří (advisor)
This bachelor thesis deals with automatic tools change on machine-tools. In the thesis, there is a research from the issue of ATC on machine-tools, focused on individual types of tool magazines. Then the necessary construction calculations are made there. Based on the calculations, the disk-type magazine is designed in 3D software. Assembly drawings and production drawings of three components are also part of the bachelor thesis.

Design of ATC System
Kolář, David ; Tůma, Jiří (referee) ; Blecha, Petr (advisor)
The first part of the thesis is focused on summarisation of commonly used conceptions of automatic tool change systems, especially focused on milling machines. Special attention is given to the issue of single tool change systems using storage tool magazines. Considering the following construction theme of the thesis, most commonly used spindle clamping units were described. With use of the gathered information was then created the construction draft of the ATC system suitable to be used with a numerically controled milling machine. Solution of the issue consists of the static structural analysis of the clamping unit using the finite element method and design of the belleville springs set. Final output of the draft comprises of drawing documentation of the main parts of the system.

Automatic tool change systems in construction of machining centers
Labounek, Dalibor ; Pavlík, Jan (referee) ; Blecha, Petr (advisor)
Automation tool change is a major factor that affects the overall level of factory automation machinery. Due to its large number of tools for machining, the system of automatic tool change (hereinafter referred to as "AVN") address one of the first questions. The help of the AVN minimize secondary production times and operator intervention while increasing productivity. With that is also linked to higher safety and minimizing human error. AVN systems expand opportunities working in the engineering industry, which is positively reflected in the price. The theme of the present thesis deals with the analysis of the problems of automatic tool change in the structure of machining centers.

Description of automatic tool change systems in machining centers
Glogar, Matěj ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
Automation of tools changing belongs to key issues how to increase universality, flexibility and total level of automation of processing production machines. We don’t usually manage with one active term (tool) in the cause of the mechanical machining only but we derive benefits from many different tools in the appropriate operation circle. Therefore the first matter of raising productivity of machine-tools was a necessity to change automatic tools. The main contribution of automatic tools changing that are used by numerical control machines is a possibility of automatic control of whole machining on the one specific machine. An automatic tool changing contributes to reduction of operation time and to reduction of the amount of operation’s intervention during the industrial process. This is related to elimination products inaccuracy, that is caused by human factor (e.g. bad tool’s position) and increase of safety at work. The aim of this bachelor’s thesis is to make a literature research and to characterize automatic tools changings, which are used by machine-tools with a horizontal spindle.
