Production of threads in thin-walled parts
Václavek, Petr ; Slaný, Martin (referee) ; Kalivoda, Milan (advisor)
The aim of this bachelor thesis is to describe and compare technologies used in a production of threads in thin-walled parts. It includes descriptions of commonly used materials for these parts and their qualities, that may have an influence on the thread production. The following are the descriptions of different methods of manufacturing threads directly into thin walls, forming different types of bushings and anchoring threaded fasteners. Special focus is on a comprehensive analysis of processes of welding, riveting and pressing nuts. The technological and economic suitability of each solution is then compared.

Design of replicated production of the selected part and verification of shape and dimensions using optical 3D scanning methods
Šrenk, Jakub ; Fiala, Zdeněk (referee) ; Slaný, Martin (advisor)
This work is engaged in the prototype casting of resin with usage of reverse engineering technology and rapid protopyping. Surface quality and dimensional accuracy was optimized in a production process. The technology of 3D scanning, rapid prototyping, soft tooling and finishing methods is discussed in the theoretical part. Then in the practical part there is analyzed manufacturing process of the selected component for replicated production. 3D scanning, additive technology, soft tools and surface finishing methods were used in the manufacturing process. In the last step, the dimensional accuracy is evaluated and also the technology for serial and piece production was chosen.

Design of replicated production of the selected part using the technology Reverse Engineering and Rapid prototyping
Kolář, Jakub ; Jaroš, Aleš (referee) ; Slaný, Martin (advisor)
This study has been as a diploma project at BUT. Theoretical part describes the most used methods in Reverse engineering and Rapid Prototyping. Each method describes its characteristics, usability and pros and cons in general. Practical part of this study deals with application of these methods. Goal of this work has been to obtain a digital model of a winker from Škoda 1000 car using optical scanner ATOS, making a new master model in CATIA software, analyzing its dimensions compared to the scanned model and choosing a suitable manufacturing technology with emphasis on functional properties of this component.

Suggestion of the manufacturing technology of a fastener for plastic molding
Duda, Tomáš ; Slaný, Martin (referee) ; Jaroš, Aleš (advisor)
The diploma thesis convey the information about the creation of technological procedures leading to the optimal way of repairing damaged parts of the fixture and creating production procedures for the production of new parts of the assembly. The theoretical part is focused on the analysis of the issue, determination of material of damaged parts for future production and designed semi-finished product. Furthermore, the technology of production from the point of view of used technologies is discussed. This includes a description of the tool materials. The practical part of the thesis is focused on the design of technological procedures for repairing damaged parts, which must be repaired as soon as possible. For the future production of new parts, the second half of the practical part includes the manufacturing processes including their description. There are evaluated variants of repair and production of new parts at the end of the thesis.

Force loading of milling tools during the machining process
Procházka, Luděk ; Slaný, Martin (referee) ; Polzer, Aleš (advisor)
The thesis deals with the problem of force loading during machining of thin-walled parts. In the theoretical part, the force load applied during milling and the possibility of measuring of the force loading during milling is analyzed. Further the work focuses on the machining of thin-walled parts, problems in machining of these parts and the possibility of eliminating these issues. The practical part deals with the design and realization of the measurement of the force load on the selected components. The thesis also presents a comparison of the simulation model of deflection of thin-walled parts with the values measured in real machining.
