Use of laser machines for engraving
Bernátek, Vojtěch ; Dvořák, Jaromír (referee) ; Slaný, Martin (advisor)
The diploma thesis covers laser engraving machines topic. In the theoretical part, it briefly covers laser technology and laser engraving in general. It also mentions history of laser engraving, especially rise and development of the laser itself, laser engraving, as well as characteristics of laser engraving machines. A description of laser engraving machines parts and the working principles of laser technology as such are also included. All objects and materials suitable for laser engraving are also described is the thesis. Furthermore, comparison of laser engraving and other traditional methods of micro machining or surface treatment in general is depicted. In the practical part, thesis deals with the goal of finding the exact corrections on the laser engraving machine necessary to be made when using swing method. Major advantage of this method is its time saving ability during the engraving process, but the corrections mentioned above are needed as inaccuracies emerge due to the kinematics and dynamics of the machine. Last, but not least, ascertained corrections were plotted into a graph and a sample product was engraved using the corrections found.

Design and production of a CNC engraving machine using an LED laser module
Novotný, Matěj ; Zemčík, Oskar (referee) ; Dvořáková, Jana (advisor)
This work focuses on the evaluation of the current state of the art and comparison of the properties of beam unconventional technologies. It discusses laser devices and the engraving process. It then focuses on the design and fabrication of a CNC engraving machine assembly using LED laser module. It describes the components used individually, their function, features, equipment to design and then the complete physical assembly of the device. Functionality was tested based on several engraving and cutting tests. Finally, the economic part of the project was discussed.

A design of engraving plotter
Brtník, Vojtěch ; Tůma, Zdeněk (referee) ; Tůma, Jiří (advisor)
This bachelor thesis, in addition to the actual design of the laser engraving laser, contains basic information about laser engraving technology and marking used in industry. It explains the physical principle of the laser and the laser source, which is essential to understand and classify laser modules. Provides an up-to-date market survey of the laser engraving modules and engraving plotters in use. In the design part, the design of an engraving plotter for SMC company is carried out using 3D models in Solidworks 2022 according to the specified parameters. The plotter design includes the selection of a suitable linear motion unit with electric drive, the assumed control, control calculations and the design of the plotter structural elements. The next section deals with the design of the support part and includes safety and functional elements. The paper concludes with a cost evaluation and recommendations for practice.

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.

Design and manufacture of an engraving LED laser
Vodička, Jiří ; Slaný, Martin (referee) ; Dvořák, Jaromír (advisor)
The thesis deals with the current state, principle and use of unconventional machining technologies. It also includes the design and assembly of a engraving laser prototype, with an emphasis on simplicity and functionality. It was an effort to acquaint not only those interested in this activity with the engraving procedure, but also to make the prototype and its use accessible to everyone with a basic awareness of CNC control. Upon completion, a test was performed on the basic materials and the resulting engraving quality is evaluated in the thesis.
