Production of a Component "Disc"
Kačírek, David ; Jaroš, Aleš (referee) ; Kalivoda, Milan (advisor)
The present bachelor thesis deals with a proposal for production of the component "disk" in two variants in conditions of a smaller company. A part of this work is to design the stock component, to select a machine out of those available in the company, and to select the appropriate tools and cutting conditions. For both variants, tools paths were simulated in the program HSMWorks and machining times were compared. The proposed optimal solution will serve as a basis for real production.

Optimization of process parameters for the laser welding of thin-walled blanks of stainless steel
Kačírek, David ; Daněk, Ladislav (referee) ; Mrňa, Libor (advisor)
For increase productivity, the current technology of welding pipes bellows was replaced by laser welding. Experiment was carried out on the material of austenitic stainless steel 1.4541 for sheet thickness 0.25 mm and 0.15 mm. On sheet 0.25 mm was achieved comparable mechanical properties as the current manufacturing process upon achieving 10 times higher welding speeds. Samples of 0.15 mm thickness achieved to about 30% lower deepening over existing technology. For improvement was advised to reduce heat input. From an economic assessment shows that the price per 1 m of weld decreases with increasing speed welding. With higher welding speeds reduces the heat input.
