Design of a milling table for machining wooden boards
Uhlíř, Radim ; Mazal, Pavel (referee) ; Čípek, Pavel (advisor)
The bachelor's thesis deals with the design and implementation of a milling table for machining wooden boards. In the research part, an analysis of the solutions available on the market was performed together with an analysis of workpiece fixtures, hand milling fixtures and linear guides. Based on the research, two conceptual solutions and several variants of structural nodes were proposed. The most suitable constructional solution was selected from the conceptual solutions, calculations of critical nodes were performed and drawing documentation was made. Subsequently, a prototype of the table was made and its functionality was tested. The table can clamp and machine a wooden board with maximum dimensions of 1000 x 800 x 100 mm.

Design and optimization of a headstock for machine tools
Lekeš, Petr ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
This diploma thesis deals with the design and optimization of a headstock for machine tool. Thesis was focused to comparison of several types of slide-ways and linear guides of headstock, considering their static and dynamic rigidity. An overview in the field of machine tools, their static and dynamic properties, use materials and design of headstocks, considering types of guideways, types of guideways drives and types of drives of spindle was made. Among the other main goals is included design of several types of guideway of headstock for horizontal machine tool, elaboration of computational models and evaluation of results.

Drive and leading of laser pointer
Dostál, Petr ; Studený, Jiří (referee) ; Škopán, Miroslav (advisor)
This master thesis deals with a construction solution for traversing of laser pointer, which is used for position identification for stock removal from the storage unit SSI Logimat, including a construction solution of leading of this traversing. The first part contains a research of storage systems used in logistics, as well as systems upgraded with laser pointer. In main part are described the suggestions of leading of laser pointer traversing, together with the design of mechanical transmission and components associated with mechanical transmission. Subsequently the drive of spin of the laser and drive of mechanical transmission are designed. Selection of drives is verified by calculation. The final part contains the check of leading of traversing by strength calculation for bending, from which is suggested the design of leading reinforcement.
