Production process for a replica of a historic firearm
Čech, Jakub ; Chladil, Josef (referee) ; Kalivoda, Milan (advisor)
This thesis deals with the production of a prototype pistol with a wheel mechanism. In the theoretical part the history is described together with the terminology focused on firearms up to the 17th century. This is followed by a demonstration of the design of the gun in the software version and a demonstration of the machines that were used for the production of the prototype. The practical part describes the production process of some components needed to make the pistol mechanism, together with the overall evaluation of the final product.

Design and manufacturing of an engraving LED laser
Hlaváček, Petr ; Kalivoda, Milan (referee) ; Dvořák, Jaromír (advisor)
The bachelor's thesis is divided in two main topics. In first one it characterizes what unconventional machining methods are and divides them into groups according to the material removal effect. Each method is always simply and briefly explained. The purpose of this part is to introduce the unconventional technologies and their use in mechanical engineering. Second major topic follows comparison between beam methods and is dealing with the design and construction of a laser engraver. The goal is to build a prototype that allows not only engraving but also cutting into materials such as cardboard. The primary purpose of this machine is the production of kits for model railroad. The last chapters are about economic evaluation and comparison between made prototype and commercially sold engraver.

Machining of a component for an electric motor stator
Balajka, Radek ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis presents a proposal for the production technology of a component for a stator of an electric motor using machining. First, an analysis of the manufactured component and the assembly unit was conducted. Subsequently, a comparison of semi-finished product manufacturing methods was performed, where laser cutting was chosen. The bachelor thesis includes the development of a technological procedure, including the selection of machines, a list of tools, and measuring instruments. Finally, a technical-economic evaluation was carried out, from which the time to produce one part and the cost of the series produced were derived.

Woodworking machines for furniture industry
Tomalík, Jan ; Chladil, Josef (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with woodworking machines that are used in the furniture industry to produce furniture parts. Initially, this topic describes wood as such. It discusses in detail its structure and composition, which are important in determining the physical and mechanical attributes of wood. The topic then focuses on the main machining methods by which wood can be processed, including the machines used for this purpose. Problems in sawing wood, that are caused by defects in the tool or in the material being machined, are mentioned. There is also a brief classification of furniture products according to the furniture standard, where furniture is classified using several factors. Finally, all the woodworking machines and methods are interpreted on the design of a wine rack, the manufacture of which is discussed in detail from the initial collection of the semi-finished product to its final assembly. A technological process is drawn up for all the parts needed to assemble the stand, accompanied by drawings.

Cutting and non-cutting operations
Morcinek, David ; Kalivoda, Milan (referee) ; Dvořák, Jaromír (advisor)
This bachelor's thesis focuses on the study and description of fundamental concepts of cutting and non-cutting machining within the field of engineering technology. The work provides a general overview of individual methods of cutting and non-cutting machining, including their principles and applications. Specific technologies of cutting and non-cutting machining are selected and applied to a chosen component within the thesis. Emphasis is placed on the study and description of specific application areas for both methods, encompassing their advantages, limitations, and contributions to specific manufacturing processes.

Measurement of small arms components - influence of grinding technology
Havlík, Daniel ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
This master thesis deals with the problem of measuring the surface texture parameters of a small arms component when applied to the hammer of a revolver. The measured component was manufactured by chip machining, specifically by grinding technology. The paper describes the design and execution of an experiment aimed at monitoring the effect of changes in technological conditions (cutting conditions) on the surface texture of the component.

Gears created by 3D printing for consumer use
Chládek, Vilém ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with gears and subsequently with 3D print. 3D print is nowadays a rapidly evolving technology which can solve complex assemblies. This text contains gears analysis and their parameters. The next section describes 3D printing technologies and the materials used. The main point of the solution is elaboration of the 3D model of a hand-powered drill and its subsequent 3D print. With this is discussed, the issue of fitting, model assembly and post-processing. A successfully printed and functional drill can be then used for educational purposes or as a suitable pattern for the kit.

Technological processes involving manual work
Krucina, Mikuláš ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with machining and at the same time manual work needed in industrial production. The purpose is to describe in general the machining process and machining technologies of turning, milling and drilling, which are among the machine machining methods. The next part focuses on the characteristics of manual operations in production, especially on measuring, scribing, sawing, filing and cutting. The last part of this topic deals with the production process of plastic windows and doors, related to the manufactured order.
