Hardness measurement of metal materials
Trčka, Tomáš ; Kandus, Bohumil (referee) ; Podaný, Kamil (advisor)
The hardness is the mechanical property of each metal material that affects his behaviour. There are many methods of measurement. Each method has its advantages, shortcomings and possibilities of use. The best known tests are according to Brinell, Vickers and Rockwell. The newer methods with portable hardness tester are UCI, TIV and the dynamic method by Leeb. The tests are carried out by mechanical pressure load using the impact body (indenter) of the harder material than the test material. The experimental measurement was executed on the three types of cutting inserts with different nominal hardness made from cemented carbides using the Vickers method with the load of 10 kp and 30 kp. The highest value of hardness was measured on the cutting insert SMG02 - 1988 HV10.

Proposal for methodology of testing sintered carbide cutting tools during high feed milling
Frank, Ondřej ; Binder, Martin (referee) ; Sedlák, Josef (advisor)
The aim of the bachelor thesis is to evaluate and compare the properties of a selected type of milling cutter from the company Dormer Pramet, s.r.o. and several competing milling cutters with replaceable inserts for high feed milling. The first part deals with an introduction to the issue of high feed milling and the characteristics of replaceable inserts made of sintered carbides. The second part of the thesis deals with the description of selected types of milling cutters used in experimental tests, the characteristics of machined materials and used instrments. The third main part deals with the measurement and results of the performed cutting tests. In the end, the results are evaluated in the technical-economic evaluation.

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.
