Technology cutting on CNC machining centres
Martiňák, Marek ; Sedlák, Josef (referee) ; Prokop, Jaroslav (advisor)
The aim of this bachelor’s thesis is to prove the mastery of the fundamental principles of technological background processing for CNC machining center CW 800. After studying specialized literature and gaining practical experience while working on the machinery in question, a technological characteristics of machining centres has been compiled, including the technological parameters of the above mentioned CW 800. Based on the sample of a concrete product, a machining technological process of the given part has been designed, including the programme itself. This design can serve as a model sample for generally applicable processing of technological background with other parts as well, on the basis of the submitted drawing documentation.

Coated cemented carbides
Foltýn, Michal ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
This bachelor’s thesis is focused on coated cemented carbides, methods for coatings and properties of coatings. In the first part of this thesis there is mentioned basic subdivision of tool’s materials, including description of properties and possibilities of their use. Another part of this thesis is focused on the coating deposition methods. As each method there is noticed the description, advantages and disadvantages. In next part there are described processes which precede own deposition process and their influence on properties of coatings. In this thesis are also described properties of coatings and methods for their testing. The last part of thesis is focused on the offer of certain producers of coated cemented carbides. Several materials are chosen from each producer and there are mentioned descriptions of their properties, structure of coatings and possibilities of using.
