Design of a small universal grinder for sharpening tools
Grym, Filip ; Huzlík, Rostislav (referee) ; Pavlík, Jan (advisor)
This thesis deals with the design of a small universal grinder for tool sharpening. The thesis begins with an introduction to the issue of tool sharpening, drilling, milling, and turning. Further, a market research and analysis of user needs is conducted. Based on these findings, several different variants of devices and methods for grinding are proposed, from which one is selected. Based on the selected variant, a 3D model and drawing documentation of selected nodes are developed. The functionality of the design is verified by basic calculations.

Virtual commissioning of a robotic welding workplace
Provazník, Adam ; Pavlík, Jan (referee) ; Vetiška, Jan (advisor)
This bachelor thesis is focused on the design of a robotic welding cell, a clamping fixture for a given component and subsequent virtual commissioning of the workplace. In the theoretical part is examined a current knowledge of industrial automation and robotics, as well as MIG welding method. An analysis of the clamping fixture and workplace, and a summary of the main aspects for their design are carried out furthermore. In the practical part are designed 3D models based on the previous analysis. A control program is created for these models and the workplace is virtually commissioned.

Extruder design for special 3D printing
Šedý, Karel ; Vetiška, Jan (referee) ; Pavlík, Jan (advisor)
The bachelor thesis deals with a design and construction of an extruder for 3D printing of ceramic clay. The author aims to find a simple method of assembly and cleaning of the extruder. In the introduction of the bachelor thesis, the reader is briefly introduced to the history of 3D printing. Furthermore, the thesis examines 3D printing and ceramic clay, including its types, properties, and suitability for 3D printing. In the following chapters, possible problems with ceramic clay printing and how to avoid these problems are described. A multi-criteria analysis including key parameters and their weights was used to select a suitable design option. The final chapter provides a detailed description of the chosen variant's construction.

Logging station for humid environments
Pavlík, Jan ; Roubal, Zdeněk (referee) ; Szabó, Zoltán (advisor)
This thesis is about the design of a meteorological station deployed in a wet environment and its construction. The station will be used for measuring meteorological instrumentation in caves, because of that the station was designed to minimize its power consumption. Firmware was designed, to allow remote control of the station. A major part of the thesis is concerned with selection and description of the sensors and components used. Near the end of the thesis the control algorithm, communication interface and construction of the device is described.

Design of a small lathe for wood
Mečíř, Václav ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
The bachelor's thesis describes the design process of a small wood lathe. The proposal itself is preceded by acquaintance with the issues and technical possibilities of this time. This is related to market research and comparison of individual lathe variants, with respect to the required machine parameters. The subsequent design contains a calculation report in which the transmission system and the spindle design, on which the greatest emphasis is placed, are solved, as it is the most important part of the lathe. Based on the calculation report, a 3D model and drawing documentation is created in Inventor 2021.

Design of a portable machine for machining large diameter pipes
Boháč, Josef ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This diploma thesis deals with the design of a portable machine for machining large diameter pipes. This thesis is divided into research, calculation, design, and construction parts. The introductory part is devoted to research in the field of joining large diameter pipes, with a focus on flanged and welded joints. Based on the findings from the research part, several construction solutions were considered. In the next part, the most suitable design solution was selected using a multicriteria analysis technique and subsequently elaborated on in detail. The following chapter deals with the calculation of maximal cutting forces and the selection of motor. An air motor was chosen as the most suitable option for the proposed machine. This part is followed by the computational part, which includes strength calculations for the critical parts of the machine. The final part of the thesis is devoted to the construction itself and the description of the individual construction nodes of the machine. The thesis also includes a 3D model, drawings of selected parts, and an assembly drawing.
