Milling cutters for CNC machine tools
Janošek, Martin ; Sámelová, Vendula (referee) ; Humár, Anton (advisor)
My bachelor thesis is about milling cutters for CNC machine tools. First the thesis deals with milling theory. There are fission tools or fission machines. Next chapter is about holding tools. The practical part deals with an assortment of production of milling tools for milling flat surfaces made by three milling tools producers. These are Sandvik Coromant, Pramet Tools and Walter companies. In the end of my work these companies are evaluated from different points of view.

Design of a simulator module for analysis of friction and wear of teeth during cleaning
Snopek, Lukáš ; Streďanská, Alexandra (referee) ; Vrbka, Martin (advisor)
This thesis focuses on the design of a module for the tribological simulator Bruker UMT TriboLab, which will be used in research in the field of analysis of wear of hard dental tissues and filling materials due to tooth cleaning. The aim of this work was the design of experimental conditions, module construction, creation of drawing documentation, production and subsequent implementation of a validation experiment. The conditions of the experiment were determined on the basis of research and to create an optimal design solution, prototypes were continuously produced using the 3D printing method. Finally, two toothbrush fixtures and two dental filling sample fixtures were made based on the drawing documentation. Subsequent assembly of the fixtures and the implementation of the experiment on the tribometer verified their functionality, which makes it possible to declare all the goals successfully met. Now these fixtures will be part of several research tasks in the field of oral biotribology.

Description of tool clamping interface at milling machines
Bartušek, Jiří ; Bilík, Martin (referee) ; Pavlík, Jan (advisor)
This bachelor’s thesis describes the types and characteristics of tool holders for milling machines, which are clamped in the spindle of machine. There are explained the structural and functional properties of individual toolholders. It also describes mechanisms for clamping tools with cylindrical shank in the toolholder. This work describes the use, advantages and disadvantages of the toolholders.

Design and Production of Clamps for Mandrels ISO 40
Tomešek, Viktor ; Kalivoda, Milan (referee) ; Sedlák, Josef (advisor)
Main aim of this bachelor’s thesis is to design and product clamp for mandrel ISO 40. This clamp will replace the other one, which is used in the milling workshop C2 on BUT Faculty of Mechanical Engineering. It will ensure easier and faster operator’s work during tool change. Also manufacturing process, selected material and cutting conditions are described in this thesis. Theory necessary for an understanding of the issues is stated in introductory section. In the final part, there is executed technical-economical evaluation with the overall costings associated with the production of the clamp for mandrel.

Body manufacture of a key lock
Leden, Pavel ; Madaj, Martin (referee) ; Kalivoda, Milan (advisor)
The diploma thesis is focused on the production of body for cylinder locks. This is production of very small and accurate parts. In the first part there is described the function of the lock, the sort of cylinder locks, their components and the basic types of safety elements. The second part is focused on the production of given type of body. The thesis deals with either existing production technology or proposals of possible innovation. This firstly consists in new organization of manufacturing operations. At the close we can find comparison of existing technology and new proposal.
