Technology Design Components Bearing Cover
Veselý, Libor ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with the design technology for product components "bearing cover“ in two variants. The first of them is designed for the production of one-piece components in company conditons. The second is concerned with the design technology for serial production of the same components using machines and tools from current production. The thesis contains designs for semi-finished components, the selection of machines from the company fleet, the design of suitable tools and cutting conditions. An economic evaluation deals with the determination of machining times for both variants of production. The proposed technology will be used for the real production of components.

Sinumerik 840D control system for programming of blanks for gear manufacturing
Havlát, Pavel ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
The master thesis deals with the use of the Sinumerik 840D control system for programming of blanks for gear manufacturing. The first part of the thesis is focused on analysis of machinability of the material followed by experimental testing of machinability of material 16MnCr5. An experimental evaluation of the effect of cutting parameters was carried out to force load of semi roughing cutting tool CoroTurn 300. In the next part of the thesis there is a technical documentation of gearing parts, for which a NC program is created. Finally, the possibilities of using the Sinumerik 840D control system are listed and demonstrated by workshop-oriented programming of the considered components for the SP 280 SY turning center.

Roller-burnishing technology as finishing oparation.
Sekerka, Vít ; Sedlák, Josef (referee) ; Zemčík, Oskar (advisor)
This bachelor thesis deals with chipless finishing operation of roller-burnishing. It explains and describes basic ideas concerning finishing and hardening of machine components by means of roller-burnishing, parting of tools, application in manufacturing and techno-economic usage. Own project, which deals with rollerburnishing of inside conic surface, is part of the thesis too.

Technology production of die
Kubášek, Pavel ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The aim of the master´s thesis is to adjust the technology of machining of a die on the CNC lathe so that the total time for the production of a die could be reduced significantly and in this way also the production costs. The analyse of the technology of the machining of the inner part of the die is carried out and a change in the machining of this part is suggested. The new technology is elaborated in two variants when the CAD/CAM system is used for the creation of a programme in a variant and the machining cycles in the other. The technical and economical evaluation is performed at the end of the thesis.

Large Turning Centres
Nábělková, Irena ; Jaroš, Zdeněk (referee) ; Blecha, Petr (advisor)
This bachelor's thesis is dedicated to large turning centres. The first part thesis is the summary of large turning centres, their description and types. Usage possibilities of different large turning centres in cutting operations are mentioned too. In the second part, the calculating proposition of a chosen component of large turning centre is solved. This component is spindle-drive. Calculating proposition contains calculation of cutting force, power, total efficiency, utile work and energy.

Production process optimization
Hejzlar, Aleš ; Vacek, Jan (referee) ; Fiala, Alois (advisor)
This diploma thesis deals with the production process optimization. The cutting operation and the lathe-turning issue is described in this thesis. In the practical part the production process is analyzed, the designed experiment (DOE) is suggested and evaluated. In the end of the practical part there is the evaluation of the machined material in the light of microstructure. On the basis of the partial findings the enclosures are done and the recommendations leading to the production optimization are suggested.

Design of multi-functional machining centre
Neumann, Ondřej ; Holub, Michal (referee) ; Blecha, Petr (advisor)
Design of multi-functional machining center The purpose of this diploma thesis is a design of turning table for multi-functional machining center. The first part is the background research of multi-functional machining centers, rotary tables, chip management and brief overview of chosen machining center’s manufacturers. The sphere of using of the designed machine, including parameters of turning table, and its basic parameters are determined on the basis of this research. Afterwards, the variants of turning table drives are drawn up and one variant of calculation and construction is made. Design of clamping desk and chip management of the machine is also made. Above a specified framework of this thesis, simplified machine foundation design and anchoring of machine parts to this basis is performed. The work also includes a 3D model of turning table and substructure. The complete set of constructed machining center was brought into immersion virtual reality environment.

Cutting ceramics and its effective use
Heča, Jan ; Sámelová, Vendula (referee) ; Humár, Anton (advisor)
Thesis dealing with cutting ceramics and its efficient use. Introduction describes the general characteristics of the cutting of ceramics, its history and development and production of various kinds. This section describes the mechanical and physical properties with potential application in machining. The se-cond part is an overview of cutting-frame in the range of selected world leaders. Ano-ther section focuses on general assessment of the power of cutting tools and other ma-terials comparison. The fourth part, is comparing the working conditions of producers and tools intended for cutting.
