Production of rotational parts on a CNC machine
Hort, Zbyněk ; Dvořáček, Jan (referee) ; Kalivoda, Milan (advisor)
The main theme of this thesis is a design of rotary part (shaft) production. The study contains the choice of semi-finished product, technological procedure, manufacturing instructions, design and description of machines and tools. It also includes a production drawing of a shaft and NC program by which a functional sample was produced. The economic evaluation is at the end of the thesis. The thesis meets all requirements needed for shaft production using CNC machines.

Production of short shaft by extrusion
Hondl, Jiří ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
HONDL Jiří: Production of short shaft by extrusion. The project prepared as part of the Master-degree studies in the Engineering technology concerns the technology design for manufacturing a short shaft by extrusion. On the basis of the study cold forming methods and problems and following technical calculations was designed a four steps process of forming. Semifinished product has a cylinder shape with a diameter of 18mm and a length of 51,2mm. The production is designed for automatic multistage press TPZK 25 with nominal pressing force of 5 000kN from Czech producer and supplier of machinery Šmeral Brno company. Tools are made of tool steel, extrusion punch and extrusion die is designed of 19 830.4 steel, and extrusion die´s band is designed of 19 733.4 steel. Tools are designed to be improved by hardening and drawing.

Production of steam turbine shaft
Krška, Jan ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
The main aim of this bachelor thesis was to design the production of steam turbine shaft for machines tools that have „higher“ technical possibilies. Nowadays these „higher“ technical possibilities have machines which are controlled by computer, i.e. CNC machines. The introductory part of the thesis deals with steam turbines, including the steam turbine shaft. The following part of the thesis describes the production of this shaft on conventional machines. The production of the shaft includes, among other things, a technological procedure including used machines and tools. This is followed by a modern approach to production, using a CNC machine. The technological process is followed by the production of the shaft on reduced form. The final phase of the solution is devoted to technical-economic evaluation of the technology, including the financial aspects of the component and, last but not least, the impact of the technology on the environment. The final part of the thesis is extended by a discussion that evaluates this issue.

Engineering design of conveyor
Chmelík, Jiří ; Čípek, Pavel (referee) ; Foltýnová, Dana (advisor)
The bachelor thesis deals with the design of a conveyor for transporting welded beams with variable dimensions. At the beginning of the work are listed some conveyors, which are commonly used in practice. Following analysis of available design solutions, design designs of equipment, their description and based on comparison was chosen the most suitable design solution. In the course of work is performed safety analysis of selected nodes. At the end of the work is evaluated the whole construction and elaborated the drawing documentation of the device. The proposed solution can also be used to transport parts of similar shapes.
