Cemented carbides and theirs effective use
Dembek, Jiří ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
This diploma thesis is aimed on cutting tools made of cemented carbides. It characterizes marking, production and properties of non-coating and coating cemented carbides and describes the latest trends in coating. Target of this diploma thesis is comparison of assortment of two important world’s producers and one Czech producer in term of used productive technologies, products microstructure, coatings types, coatings methods and possibilities of their usage. Cutting data were evaluated and compared from obtained technical knowledge, which were recommended by chosen producers for effective turning application of their cutting tools. Recommended cutting speeds were found out for specific type of cutting material according to ISO, width depth of cut and for specific values of feeds per revolution.

Sharpening and producing standard tools on a CNC grinder Walter
Martinek, Petr ; Kouřil, Karel (referee) ; Kalivoda, Milan (advisor)
This bachelor´s thesis presents a modern five-axis CNC machine HELITRNIC POWER from the company Walter Maschinenbau GmbH, which is designed for sharpening and production of rotary, cutting tools. The project provided the most commonly used types of tools, their materials and surface treatment (coating). Furthermore, there is described the production process and sharpening of tools using control software Tool Studio, when considered appropriate wheels and clamping devices. Finally, it provided an economic assessment of costly equipment.

Economical analysis of a cutting tool
Bilavčík, Jaromír ; Humár, Anton (referee) ; Prokop, Jaroslav (advisor)
Bachelor's thesis on ”Economic analysis of cutting tools“ is devoted to economic analysis the costs of acquisition and use of different types of cutting tools, whose use has a significant influence on the economy of production and, inter alia with the costs related to the quality of the final product. Analysis of the applicability of utility properties of instruments that are used in the mechanical machining was analyzed economically advantageous for the company. This criterion must take account of the company when the production technology. Another decision-making criteria should be the final product quality. For firms pursuing the cost of quality throughout the production cycle is of course due to classical periodic sharpening cutting tools - knives, it is preferable to use instruments with tip.
