Construction and shearing tool production
Šincl, Josef ; Žák, Ladislav (referee) ; Štroner, Marek (advisor)
The bachelor work describes construction and production of the progressive tools, which is used for production of lugs for car Škoda Octavia combi. The lugs are made from material number 1.0396. There were elaborated research from the field of shearing and bending. These technologies were used for production of desired part. In the instrument are made both left and right parts, which are mirror. There are also solved different difficulties in the construction. The instrument should have life cycle 3 000 000 of produced parts. The instrument is used in the 160 tons eccentric press of brand Dirinler, model CDCS P81. To the eccentric press is connected automatic straightener and dispenser, so that there is not necessity of service. The instrument is given yet and is involved in the full operation.

Factors influencing the quality of red wine
Zechmeisterová, Lucie ; Vránová, Dana (referee) ; Omelková, Jiřina (advisor)
In my thesis, I focused on monitoring of microorganisms in the sample of red grape juice and on the interactions between yeasts, bacteria and filamentous fungi. Three different media were applied for the cultivation of microorganisms; firstly for monitoring of total volume of microorganisms, secondly for yeasts and third time for lactic acid bacteria. The indirect method was used for the determination of the amount of viable cells. This method consists in enumerating of visible macroscopic colonies grown up on agar plates. When the cells grew up, the forms of colonies were analyzed visually and the morphology of microorganisms was detected microscopically. The operating time of enzymes in grape juice in the production of red wine was monitored after application of commercial enzymatic preparation. The enzym action in grape juice was observed on the basis of the process of degradation of high – molecular substrate by enzymes through the use of Ubbelohd´s viscometer. The research findings provided a lot of knowledge about the occurance of microflora in the process of production of red wine. The commercial preparations added to grape juice played a significant role.

Stress-strain analysis of winepress frame
Vaculka, Miroslav ; Fedorova, Svitlana (referee) ; Novák, Kamil (advisor)
This bachelor’s thesis deals with stress-strain analysis of winepress frame. The press is made of self help. No analysis has been performed for it yet. The thesis contains its detailed research, then basic research about other winepresses and research in the Mechanics of Materials. A computational model was set and stress-strain analysis was done in an analytical approach and numerical approach using the program ANSYS. Everything was evaluated in the discussion of the results, including the achievement of the safety factor to limit the state of elasticity. A system approach was used in the entire bachelor’s thesis.

Using of ISA 95 for part of the production line
Horák, Lukáš ; Knobloch, Tomáš (referee) ; Štohl, Radek (advisor)
This thesis deals with the design and implementation of the ISA-95 standard on a newly created production line. The standard and its models are described in the theoretical part, following with the individual selected software solutions, which were used for the standard’s application. Subsequently, a description of the construction and program tools of both devices, which by physical arrangement and their connection create the production line, is provided. The next part of the thesis deals with the design and application of a batch control process. This is the basis for an ISA-95 standard implementation, which uses specific software resources for data acquisition and visualization. A functional verification of the production line and realized design was done within the last part. The conclusion presents an evaluation of production based on analyzed data from the test production.

Forming lines molding hot weighing up to 100 kg
Smyček, Ondřej ; Humlíček, Jaroslav (referee) ; Omes, Jiří (advisor)
This project was made within the engineering studies and its aim was to design an assembly line to product assigned components of appropriate quality and quantity, using the technology of hot extrusion, both backward and forward. A series of technology steps was suggested, parameters necessary for individual operations were set and on this basis, adequate machines were chosen. The conclusion of this work contains technical-economical evaluation for the chosen options which expects the ten-year return with average production of 40 000 pieces.
