Production of planetary gear set model on 3D FDM printer
Magdon, Jan ; Prokeš, Tomáš (referee) ; Zemčík, Oskar (advisor)
This Bachelor's Thesis is looking into designing of a planetary gearbox then subsequent production with using the Fused Deposition Modeling (FDM) technology. The first part describes the production process using additive technologies, focusing mainly on FDM technology with properties of materials used in this method, then the theory of planetary gears with their practical use. The second part is devoted to production of model planetary gearbox, which is designed with regard to possibilities of FDM printer. Single parts were designed in 3D programme Autodesk Inventor Professional 2016. Finally the product is evaluated technically and economically.

Production of flanges using the procedure PPAP , and ISO 9001
Prokeš, Tomáš ; Zahradníček, Radim (referee) ; Mouralová, Kateřina (advisor)
In the first part of this thesis is described implementation of quality management system in a small company according to ISO 9001. Next part is about production process by method PPAP. In this section is solved primarily ISO 9001 standard, statistical control of production and certification company according to requirements of ISO 9001. Second part is focused on mass production of flange by using the company facilities Kovobrábění Sobotka. In the end of thesis are reflected weaknesses of production. In the conclusion is described technical and economic evaluation of implementation QMS and machining sample parts.

Optimization of EDM process control parameters
Prokeš, Tomáš ; Beneš, Libor (referee) ; Bednář, Josef (referee) ; Matoušek, Radomil (advisor)
The dissertation thesis is focused on the optimization of control parameters of an EDM machine; the subject of optimization is cutting speed and surface topography. The first part of the thesis contains a research study on the technology of electrical discharge machining with the attention paid to the optimization methods use for control parameters of this process. The second part of the thesis is focused on real application of knowledge gained from studied sources. Here, a design of experiment aim at optimizing the parameters of the EDM machine is designed and carried on to maximize the cutting speed with the highest possible surface quallity. The result of the work is to build adequate regression models and find the optimal setting of machine control parameters.

Production technology for hydraulic pump safety valve
Matějíčková, Eva ; Prokeš, Tomáš (referee) ; Zemčík, Oskar (advisor)
The aim of this Thesis is the design of a new technology for effective production of hydraulic pump safety valve and its technical and economical comparison with the current one. First part provides general information about hydraulic pumps and tooling of safety valves, which are part of the hydraulic circuits. In the practical part, design of new technological process for the production of safety valves in the NETPOL JET company is made. The design includes selection of suitable control and cutting tools with respect to available equipment of the company. Main part is devoted to the description of the technological process, making of operating instructions and calculation of machine times. In the end, technological and economical comparison of current and proposed procedures is made.

Methods of coating and coatings analysis
Rudy, Veronika ; Mouralová, Kateřina (referee) ; Prokeš, Tomáš (advisor)
The thesis deals with the coating of cutting tools. It summarizes the types of material used to create cutting tools, the characteristics of the main coating methods, the way tools are treated before coating and methods of testing the physical properties of coatings. The practical part contains the description of coating deposition on interchangeable cutting blades, where two types of coating were tested (SHM1 and SHM2). Furthermore, their mechanical and physical properties were tested. The analyzes used were adhesion and cohesion tests, coating thickness and hardness along with the chemichal composition.

A complete project and realization of manufacturing a component on a CNC milling machine
Prokeš, Tomáš ; Kalivoda, Milan (referee) ; Mouralová, Kateřina (advisor)
Technological preparation and production of a component called a blade in a small tool-company. Preparation procedure of the production and the production itself has been divided into several chapters. In the individual chapters there has been introduced the usage of CAD / CAM system, a specially programme Autodesk Inventor Professional 2014 for creating 3D and 2D documentation as well as programmes FeatureCAM 2014 made by company Delcam for creating technology and creating NC programmes for CNC machines. In this thesis there is also used a Process flow diagram and an explanation of it's importance for production. The following chapters describe the preparation process step by step and the production itself of the trial component using the facility of a company's base Kovoobrábění Sobotka.

The effect of a nozzle channel on printing parameters of FDM 3D printer
Rygl, Filip ; Prokeš, Tomáš (referee) ; Zemčík, Oskar (advisor)
This bachelor thesis follows up the influence of the nozzle channel on different parameters of printing using FDM / FFF method. The first part briefly describes the inclusion of this method in additive technologies. Then follows the description of the device for this involved method, printing parameters and research of used polymer materials. In the next chapter is proposed an experiment to test selected print parameters and there is described used equipment. The following part documents the outputs of the tests, their evaluation and comments.

Design and ergonomics of hand tools
Sovják, Richard ; Prokeš, Tomáš (referee) ; Mouralová, Kateřina (advisor)
The diploma thesis is focused on the analysis of the power tools ergonomics and also on the economic impact on a sick employee in the Czech Republic. It presents the results of the characteristics of hand tools in terms of their design, usage positions and handling. It introduces current legislation and ergonomic methods, including the newly designed visual tool AAL. The tool enables ergonomic analysis of positional rotation of the limbs, torso and neck, including the input of strength and muscle parameters. AAL is integrated into Excel software with the possibility of integrating data from Rhinoceros software and the Grasshopper module, which automatically generates data. The analysis is based on 3D scans of 144 power tools that are divided into 11 groups. It analyzes 13 typical diseases and their economic impacts. From an economic point of view, the costs per sick employee are almost 57% higher compared to a healthy employee. The author's design of the ergonomic part of the tool is also part of the thesis.
