Manufacturing of Components Using Rapid Prototyping
Peňáz, Jan ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with solution of manufacturing prototype using three technologies. Two of them are additive technologies using principles of Laminated object manufacturing and Fused deposition modelling. The third technology was milling. Model of reversible turbine was used as a base for manufacturing. CAD system SolidWorks was used for the model creation, where output formats were SLDPRT and STL. For error check of STL data software MiniMagics was used. For preparation of 3D printing data softwares SD View and Catalyst EX were used. CAM system SolidCAM was used for creation of machining strategy. Devices used for manufacturing of prototypes were 3D printer Solido SD 300 Pro, 3D printer Stratasys uPrint and 5axis mill Hermle C20U. Print on 3D printer Stratasys uPrint the most advantageous technology for manufacturing one prototype.

The Production using 3D Printing of Fixture for Shaping Plastic Pipes
Tretera, Robin ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
This Bachelor thesis compares two options in production of shaping form for plastic pipe - handmade production versus 3D print technology (specifically DMLS method). The thesis contains detail description of the final part and shaping form with pros and cons of both production methods. Handmade production is more suitable for serial production with its lower price. In time pressure 3D printing comes up with its fast and repeatable results.

Welding with laser machines
Hanáková, Anna ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis is focused on the usage of laser beam and laser beam machines in engineering. It will be mainly focused on laser beam welding (LBW). History of laser, its development and principal are all described in the opening part of this bachelor theses. Types of lasers and its use are also included. Next part is focused on laser welding itself. Thus, welding methods, parameters entering the process and advantages/disadvantages of this technology are introduced. The last theoretical part includes material tests of welded joint and outputs of those tests. In the experimental part the process of laser welding itself is presented and the results of tensile test are described.

Designing a Component Technology for the ŽĎAS Company
Ločárková, Hana ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
The Bachelor Thesis is focusing on the manufacture of a gear ring assembled from two half-rings. In the first chapter the product itself, the gear ring and the company ZDAS, a.s. where it is made, are described. This is followed by component production sequence, starting with the receipt of purchase order, the pre-manufacturing operations, making the pattern, casting itself through the rough machined semi-product release to the finish machining workplace incl. making the teeth. In the next section the attention is paid to production-related critical points and the proposal of possible new version of technological process. The last section is devoted to the technological-and-economical assessment of the production proposed. The production is looked on in terms of satisfaction of the desired quality criteria. The production sequence is traced as per the schedule and the sequence of operations and/or workplaces involved in the manufacture is shown.

Machining of rotating Body-part on CNC lathe
Dlouhý, Vít ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
This master's thesis is focused on the technology fundamentals of machining for the use of the CNC lathe which was used for machining the required parts are made of stainless steel. In the introduction are mentioned the historical milestones related to machine tools. In the following chapter is analyzed machining process and related fact. A follow-up chapter contains the parameters common to a modern machine tool CNC machines. Followed by the practical part with the characteristics of the machined components. The next chapter includes a selection of CNC lathe for production. Continued by selecting the appropriate cutting tool and adjusting the machine for the given component. They were applied a total of three variants of production with the subsequent evaluation. In conclusion, it became established fact, for example, the advantages of the shape tools or the use of more spindles during the machining.

Use of Unconventional Method WJM in Condition a Small Firm
Masařík, Adam ; Slaný, Martin (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis is focused on the possibility of using the technology of water jet for stack cutting. The theoretical part deals with two types of water jets used for cutting materials and their appropriate and inappropriate application. It also includes a description of basic elements of a water jet cutting machine. In the practical part of this thesis a few samples of a component are made by abrasive water jet stack cutting. The impact of this cutting method on production costs and cutting quality is assessed afterwards.
