The study wheeled undercarriages of mobile machines
Olšovský, Petr ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
The objective of this bachelor thesis is to summarize basic findings regarding various types of wheeled undercarriages that are used on contemporary machines. The first part of this paper deals with numerous requirements that should be fulfilled by the design of an undercarriage. The fulfilment of these requirements also helps to assess whether the design should be used for a specific machine. Another focus of this paper is to summarize all design solutions regarding propulsion, tyres, stabilizing elements and steering mechanisms. These solutions are compared to each other. Important design elements of wheeled undercarriages are described as well.

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.

A new Variant of the Technology Components of the Valve Body
Kouřil, Vít ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
Bachelor thesis compares two technology variants of production on the inner part recess of the valve body type S43. This is a closing forged valve for power. The work analyses and displays structural design of the slide. After presenting existing technology of inner recess new technology is described in the thesis. The comparison was made with respect to machinery companies Armaturka Vranová Lhota, Inc. Assessment of better technology is described in the technical-economic evaluation at the end of thesis.

Production of a Component "Disc"
Kačírek, David ; Jaroš, Aleš (referee) ; Kalivoda, Milan (advisor)
The present bachelor thesis deals with a proposal for production of the component "disk" in two variants in conditions of a smaller company. A part of this work is to design the stock component, to select a machine out of those available in the company, and to select the appropriate tools and cutting conditions. For both variants, tools paths were simulated in the program HSMWorks and machining times were compared. The proposed optimal solution will serve as a basis for real production.

Cutting operation in condition a small firm
Hejtmánek, Pavel ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
This work is focused on standard methods of machining (turning, milling, drilling). The aim is to know the background of smaller companies and give a specific technological situation in relation to the terms of the assessment. The first part focuses on the technology of turning; it describes the distribution and usages of machine tools. The second and the third parts deal with the milling and drilling technologies that have similar content character as the area of turning. The final part of work solves technological situation in the company Kratochvíl Ladislav Kovoobráběčství and the situation is examined from several perspectives.

Technological design of a manufacturing process modernization
Vaverka, Jiří ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
The topic of this thesis is to design the modernization process. The aim of this work the design of new machines for a particular component, which would replace the existing ma-chinery used in company-tion in which the component is produced. Introduction is focused on the description of the company and selected components for which it is evaluated di-mensioning, tolerance, functionality and material. The following describes the current ma-chinery engineering company and then are selected machines in two variants, which would replace the original equipment. With these new machines is a technical documentation and is evaluated modernization and environmental concerns. At the end of the re-evaluated results that modernization is beneficial or not.

Design of portal milling machine
Lasák, Štěpán ; Tůma, Jiří (referee) ; Blecha, Petr (advisor)
This bachelor thesis is focused on the field of router type (planar) milling machines. The first part of the thesis presents a brief introduction to the described machine and its main constructional parts. After setting the area of the milling machine’s usage, appropriate parameters will be chosen. Elementary constructional are calculated based on these parameters. At last, a drawing of the assembly and a 3D model of the machine are made.
