Design and manufacture of an engraving LED laser
Adam, Tomáš ; Slaný, Martin (referee) ; Dvořák, Jaromír (advisor)
The thesis deals with the evaluation of achieved parameters of unconventional machining methods and their current use in practice. In addition, the design and construction of the prototype of the laser engraving device is carried out. Several tests are performed on the device and are compared with similar devices after evaluation. The entire construction is designed so that no special equipment is needed and the construction could be done in each workshop.

Trends of development water jet machining
Brym, Radek ; Slaný, Martin (referee) ; Osička, Karel (advisor)
In diploma thesis there is elaborated the analysis of assumed development of water jet technology and there is analyzed the level of water jet method in production. There are introduced the possibilities of new applications of water jet machining and the possibilities of it’s future development. There is think over the enlargement of this method in next 5 years. Simultaneously there is solved the question of techno economic operation severity of this technology.

Design of Technology for Cutting and Engraving of Rotary Semi-finished Products for the CO2 Laser
Šrenk, Vojtěch ; Dvořák, Jaromír (referee) ; Slaný, Martin (advisor)
The thesis deals with the design and implementation of a rotary axis in a CO2 laser cutter for the ability to cut and engrave rotary workpieces. The thesis is focused on identifying several similar available known competitive solutions, for which the pros and cons were evaluated. Based on the findings, suitable parameters were selected to achieve maximum versatility of the proposed system. Versatility in this respect is related to the ability to cut and engrave the widest possible range of rotary workpieces. The thesis also describes the design solution, axis assembly procedure, production design and production of individual components using 3D printing technology (FFF), selection of suitable standardized components and the actual implementation. The conclusions then focus on the proposed solution from an economic and technical point of view.

Proposal production of a chain wheel with the unconventional methods of machining use
Mikeš, David ; Kubík, Roman (referee) ; Dvořák, Jaromír (advisor)
This bachelor thesis deals with the application of unconventional methods in machining (use of laser and hydro-abrasive beam) during chain wheel production. Firstly, the unconventional methods are divided according to the overwhelming effect of material separation, and then these methods are briefly described. In the second part of the thesis, you can find the technological process of chain wheel production with the usage of cutting operation method, which is followed by the assessment of production costs. Afterwards, the chain wheel is produced with the application of laser and hydro-abrasive beam. The final part of the thesis contains comparison between the unconventional methods and the conventional method of cutting operation. The comparison is based on the achieved structure of surface of the gear tooth, the production time and the economic point of view.

Nekonvenční metody obrábění materiálu
LARVA, Jaroslav
The bachelor thesis deals with the summary and characteristics of unconventional machining methods used in mechanical engineering for the agricultural or automotive industry, such as chemical, electrochemical machining, electroerosive machining, ultrasonic machining, laser machining or electro beam machining. The first part includes a systematic division and characteristics of individual methods. For each method, the history, machining principle, machining equipment, advantages and typical area of application of individual unconventional technologies in technical practice are described. The final chapter contains a comparison of individual methods depending on the achieved surface quality and dimensional tolerance.
