Virtual commissioning of wax model gluing for investment casting
Maňák, Juraj ; Bražina, Jakub (referee) ; Szabari, Mikuláš (advisor)
The thesis deals with the virtual commissioning of a robotic workstation for gluing wax models for investment casting. The theoretical part describes the concept of Industry 4.0 and its main pillars, followed by the technology of investment casting and the entire process from wax mold to casting. The next part summarizes the knowledge of robot programming methods and virtual commissioning. This is followed by a chapter analyzing the current methods of gluing and describing the individual components of a universal workstation.The practical part begins with the design of the robotic workstation, including components such as positioners and grippers, and their subsequent description. The next part focuses on creating a simulation in the Process Simulate software, including the definition of kinematic structures and operations. The thesis also describes the process of virtual commissioning, the use of Robot Studio for real feedback, and the subsequent creation of PLC and HMI in TIA Portal.

Optimization of wax and ceramic shell technologies in the company Fimes
Kolesár, Roman ; Vašťák, Patrik (referee) ; Horáček, Milan (advisor)
The thesis continue thematically in the previous development of the wax mixtures for the company Fimes. The general description of the investment casting process from the production of the die to casting of the wax pattern is handled in the first part. It is followed by the summary of the previously carried out experiments on cracking the shells. The experimental part describes the individual operations from the production of tested wax patterns to casting in the Boilercláv. The newly developed wax mixture is compared to the wax mixture used by the company Fimes. The experiments focus on the possibility of cracking the shells during the casting process and the dimensional stability of wax mixtures.

Properties of polymer modified bitumen for warm mix asphalt
Zábranský, Ivo ; Koudelka, Tomáš (referee) ; Dašek, Ondřej (advisor)
The Diploma thesis is focus on polymer modified bitumen for warm mix asphalt. The theoretical part of the thesis describes additives which influence the properties of bitumen for their use and reduction of production and service temperatures. Further, the theoretical part describes the conclusions from the researches. This part also describes empirical and functional tests of bituminous binders. The practical part presents the results of individual tests. Tests were performed on samples of non-aged, aged by RTFOT and RTFOT + PAV methods. The results of the work and the assessment of the suitability of bituminous binders are summarized at the end of the thesis.
