Automated machining in CAM systems
Jelínek, Tomáš ; Sliwková, Petra (referee) ; Zouhar, Jan (advisor)
This thesis focuses on the possibilities of machining using CAM systems automation. For modeling components such as holders, clamps and sample parts was used software CATIA V5R20 by Dassault Systmes. These samples were subsequently used to demonstrate the automation capabilities in PowerMill Ultimate 2022 by Autodesk. The automation program is consists of created tool database, templates with machining strategy and developed macros. A technical and economic evaluation was performed by comparing programming times of the program with and without using of the created elements of automation.

Technical preparation of a handgun component production
Blažek, David ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
The main goal of this diploma thesis is to propose ways of producing a firing pin. Reverse engineering is applied to the specified component. In the first part of the thesis, the function of the firing pin, clamping of eccentric components on the lathe, types of production according to serial number and selected machines are described. The second part goes through the measurement that is implemented in the practical part. After measuring and evaluating the results, several fuze production technologies were proposed. An ISO code was created for them, which was then simulated. The times and other aspects of the given technologies were subsequently compared and evaluated. For the required series of 10,000 pcs, it is suitable to use turning technology with machined jaws or technology using pressing and compound tools.
Testing of high-temperature corrosion resistance of Inconel 625
Tomek, Jiří ; Sliwková, Petra (referee) ; Zemčík, Oskar (advisor)
The aim of the diploma thesis was to design an experiment for testing the high-temperature corrosion resistance of Inconel 625. The experiment was performed at two (900oC and 975oC) on a total of 6 samples (3 for each temperature). The experiment was performed in a dissolved mixture of salts (35% Na 2 SO 4, 30% KCl and 35% NaCl) in a „PEC Lac PK 105/12“ furnace. Based on the results of individual measurements, experimental parameters and future steps were proposed. The diploma thesis also presents a basic description of the project of which it is a part. Where the project originated and what stage it is at. The project was created based on the requirements of BPP Energy s.r.o. to develop a device for bending pipes made of 16Mo3 material with a weldment from Inconel 625. The results of the diploma thesis are also compared with the results of the same measurement, but for 16Mo3 material. In the research part, the diploma thesis deals mainly with the material Inconel 625. Furthermore, the diploma thesis is focused on high-temperature corrosion resistance, therefore the corrosion process is described. And in the completion, attention is paid to the welding process.
Disc brake design and construction for the Simson S51 motorcycle
Povýšil, Jan ; Sliwková, Petra (referee) ; Dvořák, Jaromír (advisor)
The work is focused on the design, production, and tests of a disc brake for the Simson S51 motorcycle, whose original brake system is quite problematic, has low efficiency, and is already obsolete from today's point of view. In the beginning, the work deals with the issue of motorcycle brake systems and compares individual solutions. The design is processed in CAD software Autodesk Inventor Professional 2023, including drawing documentation, and mechanical calculations of the design are mainly performed in the ANSYS 2022R2 application. The work briefly summarizes the production process used to produce the given prototype. A comparison is made with commercially available solutions and a price calculation for production is made. Finally, tests of the functionality of the physically produced prototype and a comparison with the original braking system are performed.
Design of production technology for a bearing pin
Bocek, Bogdan ; Kalivoda, Milan (referee) ; Sliwková, Petra (advisor)
The bachelor's thesis deals with the production of a rotary component – a bearing pin. First, the component itself, its dimensions and material are solved, and then a suitable semi-finished product is selected. The research focuses on the production technologies used. In the next part, the production technology of the bearing pin is proposed. The technological process consists of selected production machines and tools, production process and production control of component, including gauges used.
Design of production technology for a grinding wheel flange
Němec, Lukáš ; Zemčík, Oskar (referee) ; Sliwková, Petra (advisor)
The bachelor’s thesis deals with the design of technology for the production of a component called a basic flange. The component is used for clamping the grinding wheel and is made of alluminum alloy. First there are theoretically dismantled individual production technologies, machinability and tool materials. The production technology for production in small series is designed and machinery and tooling equipment are selected. Furthermore, the bachelor’s thesis includes technological process and manufacturing instructions, which contains the cutting conditions for each tool. The manufacturing instructions are used to determinate machine time, among other things. Finally, the actual production of the component is shown.
Design of production technology for a drive transmission shaft of a snow blower
Ulak, Ondřej ; Dvořáková, Jana (referee) ; Sliwková, Petra (advisor)
This bachelor thesis deals with the design of the technology for the production of a gear shaft for the drive of a snow blower. Its aim is a complete production design including component analysis, selection of production technology and design of production area. One of the main parts is also an economic evaluation, including a time schedule. In the course of the work, the choice of blank, cutting conditions, machining times, machine capacity and the design of machinery are addressed. The proposed technology shows that the shaft can be machined in two machining operations, turning and grinding. The project is economically profitable, the return on investment is within 3 years from the start of mass production.
Suggestion of technology for a food machine dosing component
Vrba, Lukáš ; Sliwková, Petra (referee) ; Zemčík, Oskar (advisor)
This bachelor's thesis deals with the design of production technology for the potential production order of the company. Following the manufacturing drawing, the component has a complex shape and serves as a dosing component in food processing machinery. The material of the machined component is a corrosion-resistant martensitic steel X17CrNi16-2 according to EN 10088-3. A semi-finished product was selected, and the design of the technological aspect of the component was assessed. Furthermore, a main technological procedure with a modern machining centre and a variant technological procedure was designed for the machining centre's inability to machine the component. The design included the selection of machines, tools, gauges, and a detailed manufacturing procedure with cutting conditions. An NC program was created for the main technological procedure. The designed technological procedures were evaluated from a technical and economic perspective.
