On the production of an agricultural machinery part and its optimization
Tenora, Tomáš ; Osička, Karel (referee) ; Píška, Miroslav (advisor)
This master's thesis deals with the process of machining a forged connecting rod in cooperation with the company Zetor Tractors a.s. The first chapter of the thesis is focused on a detailed introduction of the company. The second chapter includes an elaborate analysis of the technical documentation and requirements concerning the making process of the subject of study, specifically the construction of the connecting rod. In the third chapter, the current production technology is discussed and described in detail. The aim of the fourth chapter is to propose an innovative technology which can be used for the production of connecting rods in the required quality. The fifth chapter is aimed at testing the newly designed technology. In the final, sixth, chapter, a technical and economical evaluation of the proposed procedure is performed.

Rationalisation of manipulation shop
Vičar, Miroslav ; Neužil, Karel (referee) ; Hlavenka, Bohumil (advisor)
The aim of this thesis is to reach a distinctive rationalization of the production and assembling plant of Cargo Van Brno company. In the project of new lay-out of the production area were all restrictions given by management of the company and by owner of the property strictly met. Technological changes of the process plan and investments suggestions are determined by the company's strategic plan.

Machining of aluminum alloy component
Lačňák, Martin ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The thesis focuses on the technology of production of the turbine-type component in Edwards company. It specifically focuses on the part of the turning production, in which in the first part an analysis of the component and the technologicity of its construction is created. Problematic aspects are analysed in terms of material structure and procedure technology. An evaluation of the former and the new supplier is made in terms of rationalization of material structure and their statistical evaluation of rationalization improvement towards keeping to geometrical tolerances. Grooving tools greatly influence the overall machining time during turning. An experiment is made to find out the measured values of the radial forces, the process of chip formation and surface roughness during grooving. The technology of procedure further deals with rationalization of the current machine OKUMA LU25-M and purchase of a new machine Mori Seiki NTX 2000, for which new tool equipment is made in cooperation with Walter company. The final technical-economical evaluation sums up all findings from the research of the given issue. In the discussion, further continuation is suggested for the research in the development and for the continuously controlled component productivity.

Rationalization of production technology body
Dostál, Martin ; Chladil, Josef (referee) ; Osička, Karel (advisor)
In the introductory part of the thesis, there is a description of machining technologies used in the production of body. This is followed by a detailed analyse of the current technology of production of this component with an emphasis on finding its problematic parts, including a proposal of the options of the rationalization. After the methods of rationalization assesment, a new technological process was developed and the alternative tools were proposed. Considerable time and money savings were achieved by this rationalization. In the discussion section, there were designed some options of solving problems arising during the installation of this rationalization into working.

Rationalization of production end piece
Grandič, Jan ; Götz, Bohuslav (referee) ; Osička, Karel (advisor)
This thesis was created in cooperation with company Westfalia. The aim of this work is to analyze the possibility of rationalization of production of end parts for gas tight hoses used in the automotive industry. The thesis includes a study of rationalization of possible production of the second generation of end parts as well as completion of assembly line for the current generation of end parts.

Rationalization of segment production of the forming tool
Pilař, Radek ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
Master thesis is focused on the rationalization of production of the forming segment, which is manufactured by company OMNI-X CZ. Familiarization with the product „forming segment“, with issue of production with possibility improvment. The work is also focused on the preparation of the clamping fixture, which should improve the production conditions. The main point of the work include the calculation of cutting forces, clamping forces of the fixture, verification of safety process with economic evaluation. The aim of this master thesis is to indicate the possible direction of the rationalization of the manufacturing of the shaping segments for OMNI-X CZ.

Rationalisation of production technology
Konečný, Petr ; Kolář, Ladislav (referee) ; Osička, Karel (advisor)
This thesis deals with the rationalization of production technology of selected component. The first part contains a brief introduction of the company NTS Prometal Machining s.r.o. and brief description of the product. The following section is an analysis of existing manufacturing technology. The practical part is focusing on the proposal of rationalization versions of the production process. After evaluation of all possible options of rationalization there has been developed a new technological process with a respect to time and cost savings. Finally there was carried out economical evaluation and recommendation for further production of this component.

Rationalization of the clamping jaws production process for the chuck
Kovář, Matouš ; Jaroš, Aleš (referee) ; Kalivoda, Milan (advisor)
This bachelor's thesis focuses on the rationalization of the production process of chuck clamping jaws in TOS Svitavy, a.s. The introductory part of this work presents the company and its production program. It also includes the production of manual self-centering universal chucks and clamping jaws. An analysis of the existing technology of production of clamping jaws is performed and critical points of the current production process are determined. There is also a proposition of possible rationalization solutions and then the most suitable version is selected. Than, this version is processed, a new production technology is designed and a new technological procedure for the production of clamping jaws is assembled. Finally, an evaluation of the existing and newly designed technology is performed and the conclusions of this thesis are presented.
