Production of cooling cabinet
Halabrín, Marek ; Peterková, Eva (referee) ; Císařová, Michaela (advisor)
The thesis deals with presenting an assembly proposal of a cooling cabinet. The cooling cabinet is made from an austenitic steel plate of the ČSN 17 240 grade with a thickness of 1.5 millimetres. The assembly proposal is composed according to the design documentation. The number of the assembled pieces is 200. The manufacturing shall be made with the use of bending and punching. These manufacturing techniques form a part of this thesis. Finn power C5 with a nominal force of 300 kN and Trubend 5170 with a nominal force of 1700kN are the machines chosen for the manufacturing process. These are standardized machines made from a quenched steel and a steel of the 42CrMo4 type. A technological-economic evaluation comparing expenses of the manufacturing also forms a part of the thesis as well.

Bonding of 3D FDM printed parts from ABS
Halabrín, Marek ; Varhaník, Matúš (referee) ; Zemčík, Oskar (advisor)
The thesis focuses on comparisons of usability of distinct types of glues to attach specimens. The specimens were glued using 4 types of glue: BISON Power Adhesive, BISON Epoxy Universal, PATTEX Repair Epoxy 5 min and a mixture of acetone with diluted ABS plastic as the last. The specimens underwent tensile and impact tests. For the tensile test, the specimens were made in 3 variants: blunt frontal joint, bevelled joint and gradually folded joint. For the impact test, the specimens were made in the form of a rod with a V-shaped notch. All variants of the joints consisted of 5 specimens with 3 unglued specimens for reference. The testing was conducted on the ZD 10/90 tensile strength machine and a Charpy impact test machine from the WPM company. The thesis contains technical-economic evaluation of the results of the tests with comparisons of the individual glues and forms.
