Design of small hobby CNC milling machine with fixed table
Hanzal, Jiří ; Marek, Tomáš (referee) ; Pavlík, Jan (advisor)
The topic of this work is the design of a small model CNC milling machine with a fixed table for machining wood, plastic, or light alloys (Al, Zn, etc.). It also includes a calculation report and drawing documentation of selected nodes. The beginning of this work consists of an introduction to the issue of milling machines, their distribution and subsequent market analysis. Subsequently, the input parameters are designed on the basis of market analysis and in the last part there is a calculation report, the design of the milling machine itself and a short economic evaluation.

The drive of the feed coordinate portal machining center through pinion and rack
Malásek, Petr ; Novotný, Lubomír (referee) ; Marek, Jiří (advisor)
This thesis is dealing with determining of technical and economical limits of axis X of portal milling machine driven by gear rack and pinion. And designing drive of axis like this. In chapter overview of the current state of knowledge are researched options of drive systems of linear axis, primarily of using ball screw and couple of pinion and gear rack. Basic parameters of axis X portal milling machines, options of measuring, guiding of axis and electric motors. Then the limit suitability of using pinion and gear rack is determined. In next chapters is designed few variations of arrangements of drives and selected the best one. This arrangement is then designed.
