Bonding of 3D printed PET-G parts
Maxa, Ondřej ; Kupčák, Radim (referee) ; Zemčík, Oskar (advisor)
This bachelor thesis solves the problem of gluing PET-G material, which is used for printing 3D models in 3D printers. The goal is to select and then test the adhesive suitable for bonding the material. The suitability of the recommended adhesives was determined on the basis of standardized tests on experimental blasting equipment. Based on the measurement results, it is suitable to use one-component instant adhesives for gluing PET-G material, the advantage of which is easy handling and quickly achievable handling strength.

Production design of a component for aerospace industry
Kunst, Ondřej ; Kupčák, Radim (referee) ; Kalivoda, Milan (advisor)
Master's thesis deals with the design of the production of a component from the aviation industry. The first part contains an analysis of the solved part and its production variant. The second part is devoted to the theoretical analysis of the operations that were used for the production of the given part. The third part deals with the design of production technology. Here, the choice of suitable semi-finished product, CNC machines and cutting tools, the creation of a production procedure and the compilation of NC programs are solved. At the end of the thesis, a technical-economic evaluation is prepared.

Influence of surface roughness on optical properties of machined materials
Ashqar, Ghaith ; Jaroš, Aleš (referee) ; Kupčák, Radim (advisor)
První, teoretická, část této bakalářské práce se věnuje problematikám souvisejícím s výrobou mechanických položek pro optické přístroje. Poskytuje úvod k parazitnímu světlu a přehled způsobů jeho eliminace. Následuje obecná část zabývající se soustružení a sekce věnovaná měření drsnosti povrchu. V praktické části jsou tyto poznatky zúročeny v podobě návrhu a následné výroby prototypového vzorku který bude sloužit k vyhodnocení vlivu drsnosti povrchu na množství parazitního světla v optickém přístroji. Drsnost povrchu jednotlivých vzorků byla změřena a porovnána s teoretickou hodnotou získanou výpočtem. Prototyp byl vyvinut v úzké spolupráci s R&D oddělením přerovské firmy Meopta – optika, s.r.o. Na základě budoucích zkoušek a měření bude vyhodnoceno, zda je autorem navrhovaná inovace aplikovatelná v oblasti přesné mechaniky a optiky.

Machining technology with the necessity of manual work
Svoboda, Jakub ; Kupčák, Radim (referee) ; Kalivoda, Milan (advisor)
Manual work is still necessary and often irreplaceable. In most cases, it is combined with machine production. As an example of such work we have chosen the production of tin lead alloy organ pipes, which encompasses several machining processes. All aspects of production were analyzed, including specification of the materials used and the various production processes. A pipe was produced according to these specifications for illustration. Individual chapters presented special manual tools and specific machinery. The difficulty and originality of the given production was outlined. This is professional work requiring manual dexterity, logical thought, attention to detail and an artistic spirit. During production we obtained an image showing a part of the cross-section of the pipe perpendicular to its axis. The image shows the correct shape of the soldered joint and the tangential connection of both sides of the sheet. Several aspects of the pipe were evaluated. The final chapters include feedback from customers and a general assessment of this particular work.

Turning machines and tools, production of a sample part
Šaroun, Martin ; Jaroš, Aleš (referee) ; Kupčák, Radim (advisor)
This bachelor's thesis provides an overview of turning technology in the research part. It describes the basic terms and terms, deals with the division of lathes and turning knives. The practical part of the work is focused on the technological processing of the specified part, which is the assembly mandrel used for precise gluing. The technological process was developed and in cooperation with the company, the production of its own component took place. In the last phase, the final inspection of products and evaluation took place.

Machining of a flat shape part on a CNC machine
Moravec, Petr ; Kupčák, Radim (referee) ; Kalivoda, Milan (advisor)
This bachelor's thesis deals with the production of flat-shaped components by CNC milling. A production process was set up within it. Part of the production process assembly is the selection of machinery, including accessories, gauges, and technological processes. Furthermore, an NC program was created, which was optimized in production. At the end of the thesis, the production of the selected part is evaluated.
