On the analyses of cutiing tools coated with PVD coatings
Malý, Martin ; Osička, Karel (referee) ; Píška, Miroslav (advisor)
In this diploma thesis, literary research about drilling and coating technology focused on PVD coatings was performed. Furthermore, there is an overview of cutting materials. In the experimental part of the work, the attention is dedicated to tests of twist drills from cemented carbide and high-speed steel materials. For these drills, the feed force Ff and the cutting moment Mc were measured when drilling into austenitic stainless steel. At the end of this work, the technical and economic evaluation of the practical part is presented.

Machining of rotating Body-part on CNC lathe
Dlouhý, Vít ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
This master's thesis is focused on the technology fundamentals of machining for the use of the CNC lathe which was used for machining the required parts are made of stainless steel. In the introduction are mentioned the historical milestones related to machine tools. In the following chapter is analyzed machining process and related fact. A follow-up chapter contains the parameters common to a modern machine tool CNC machines. Followed by the practical part with the characteristics of the machined components. The next chapter includes a selection of CNC lathe for production. Continued by selecting the appropriate cutting tool and adjusting the machine for the given component. They were applied a total of three variants of production with the subsequent evaluation. In conclusion, it became established fact, for example, the advantages of the shape tools or the use of more spindles during the machining.

Micro-turning applications in high precision manufacturing performed by diamond tools
Švorc, Josef ; Dvořák, Jaromír (referee) ; Žídek, Jan (advisor)
Bachelor thesis is focused on micro-turning. The work takes the form of a literary research, which aims to make an overview of the production technology. First, it deals with the definition of the topic itself and with the physical properties and phenomena that occur during micro-machining. Then it discusses the construction of micro lathes and their division into categories and compares them to each other. It also deals with the cutting tools suitable for this machining process and their production and shaping. The last part of the thesis is focused on the application and utilization of micro-turning in industry and on the creation of non-rotational components and micro-structures.

Machining of polymericMaterials
Ondráček, Ivo ; Němec, Karel (referee) ; Molliková, Eva (advisor)
This bachelor’s thesis deals with the machining of polymeric materials and the major differences between the machining of metals and polymers or plastics. Introduction describes the basic elements in the history of the discovery and use of plastics. The thesis focuses on the basic division, further definitions and internal structure of the polymers. There are also discussed the most widely used machining technology and requirements for tools and materials. At the end of the work we are specified properties and selected types of plastic materials intended for processing. Practical informations were obtained during the visit to Brno company Belt Plast, Ltd.

Machining of hard materials
Pech, Ondřej ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The objective of this paper is to analyse the issue of machining of hard materials on Swiss-type automatic lathes at Decoleta, a.s. In the form of research, analyses are being done of the materials used, possibilities of the available cutting tools and suitable tooling materials. The current technology used in the production of two different stainless steel elements is further being analysed in detail, including the subsequent suggestion of rationalisation actions. These actions include, mainly, the design of new tools from CBN for both elements, which shall replace the current tools made of sintered carbide, but also reworking of production technology for the Pin on another more suitable type of machine, including a new CNC program and complete drawings.
