Proposal to Introduce a New Product to the Production Line
Dobiáš, Bohdan ; Bulawa, Lukáš (referee) ; Videcká, Zdeňka (advisor)
The diploma thesis deals in detail with the description of a product for an existing production line in the company. During the analytical part, both products, the production line in the company was described and FMEA analysis was performed to identify potential risks and shortcomings in the existing production process and future design of the product implemented on the production line. Based on these comprehensive analyses, a new assembly process was designed and developed to minimize risks and maintain the same quality of production as before. The new manufacturing process includes the introduction of new production fixtures and technologies.

Design of a new production line
Hejl, Martin ; Jurová, Marie (referee) ; Juřica, Pavel (advisor)
This diploma thesis deals with the project of implementing a production line in a selected company dealing with the recycling of plastic waste and the production of rPET flakes as a secondary raw material for the production of plastic products. First, it deals with the description of the current state and the production process in the company, including the layout of the equipment, and then defines the requirements for the project by the management of the company and individual shareholders of the company. Defining the requirements for the project and at the same time the method of obtaining key information took place on the basis of in-depth interviews with the interested parties of this project, while a pilot design of the layout of the machinery was created, including a description of the technology and a flowchart of the required production process. The main content of the design part is the creation of a proposal for a possible implementation of the production line using a network diagram using the PERT method, which indicates that the duration of the project was calculated to be 106.6 days. Together with the network diagram of the project, an analysis and proposals for managing the risks of this project were prepared. At the end of the draft chapter, a financial analysis of the project's payback period was carried out, as the condition of a payback period of 3-5 years must be met in order for the project to be approved by the shareholders, which this project fulfilled in all three expected progress scenarios.

Streamlining of the production of a component into the aircraft engine
Bula, Tomáš ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
The thesis deals with innovation of the technological process of casting called Fan support in the company Honeywell Aerospace Olomouc s.r.o. The first part of the thesis is dedicated to component description which is made of titanium alloy Ti-6Al-4V. The section is also devoted to jet engine TFE 731, which is the engine where our particular component has specific function. Another part is focused on theoretical analysis of material characteristics of titanium alloys and their machinability. In the following section there are considered alternatives of machine suppliers with subsequent selection of the multifunctional CNC milling-turning center DMC 80 U duoBLOCK equipped with Jetstream technology. The transfer of the production to another machine is accompanied by an innovation of the technological process, making new fixtures and optimalization of the cutting tools. The section is also dedicated to static analysis of the component in operation 7 supported by finite element method (FEM). The final part of the thesis includes evaluation of the costs and savings achieved by innovation of the technological process.

Design and Simulation of Micro-Bolometer in MEMS Technology
Svatoš, Vojtěch ; Pekárek, Jan (referee) ; Hubálek, Jaromír (advisor)
Tato diplomová práce zkoumá problematiku detektoru infračerveného záření nazývaného bolometr. Cílem je pokrok v detekci infračerveného záření použitím odlišné absorpční vrstvy modifikovanou karbonovými nanotrubicemi. V teoretické části jsou uvedeny základní fyzikální pojmy z problematiky teplotního managmentu a základních fyzikálních vztahů bolometru. Design bolometru je představen a popsán. Teplotně mechanické simulace předvídají chování bolometru při detekci infračerveného záření. PSpice model je vytvořen a kombinuje termální a elektrické vlastnosti čipu bolometru. Dále je uveden proces výroby bolometru, které je detailně popsán.
