Design and realization of CO2 laser with power up to 100W
Šrenk, Jakub ; Dvořák, Jaromír (referee) ; Slaný, Martin (advisor)
This work is focused on the problematics of small CO2 lasers and their possible use for commercial production. The first part describes devices available on the market and evaluation of their parameters. The practical part specifies the parameters that arise from the potential use of technology. Based on these parameters, design of the machine and its complete mechanical design are elaborated. Furthermore, the experimental part deals with the design of structural components, control system, electrical systems and in general a complex technical-technological solution of the equipment, including economic evaluation of the design. Part of the work is also the construction of the machine itself, including activation, adjustment and debugging for the considered production. The constructed machine was subject to testing to ensure required quality of production.

Surface treatment of ABS parts after FDM 3D print
Světlík, David ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
This master thesis deals with the surface treatment of parts made of plastic produced using FDM technology and design of technological device for surface treatment. The thesis describes FDM principles, according to performed experiments in a technological device there are suggested technological conditions for the surface treatment of parts made of ABS plastic. In the end of the thesis, there are calculated costs of the technological device and its operating costs, also mechanical properties, surface roughness and other specifications from before and after the treatment are compared.

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.

The use of thermovision technology in output control of power supplies
Rejžek, Jan ; Slaný, Martin (referee) ; Polzer, Aleš (advisor)
The aim of the thesis is to clarify the issue of non-contact surface temperature measurement with a focus on the thermal imaging cameras as a modern representative of pyrometers and thermovision technology used in the output control of power supply. To obtain the corresponding results of temperature control, it is necessary to know the exact values of emissivity of the measured materials. The experimental part of this thesis is focused on detection of emissivity of power supply parts.

Production of gear wheels with using dividing head
Cicha, Tereza ; Slaný, Martin (referee) ; Jaroš, Aleš (advisor)
The aim of this work is to characterize the production of gear wheels with using dividing head and also to produce the gear wheel by this method. The theoretical part of the bachelor thesis contains an overview of the machining methods for the production of gears and their characteristics. Theoretical chapters also contain a detailed description of the the production of gear wheels with using dividing head and materials used for the production of single gear tooth cutters. The aim of the practical part is to design, calculate and produce the gear wheel with using dividing head. The conclusion of the thesis is the overall summary and evaluation of the calculated data.

Design of production technology for a pinion shaft of a gearbox
Hulvej, Matúš ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
The diploma thesis presents a design of a technical project: design of production technology for a pinion shaft of a gearbox and design of alternative technology. It focuses on the analysis of a component, the selection of materials, machines and tools, and the creation of a manufacturing drawing and technological process of the production. It is concluded by a technical-economic evaluation, based on which are both designs compared and evaluated which design is better for specific conditions.
