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.

Rationalization project of air-filters production
Buďa, Vojtěch ; Heinl, Zdeněk (referee) ; Rumíšek, Pavel (advisor)
This thesis deals with rationalization layout of air and fuel filters production in the company MANN-HUMMEL (CZ) s.r.o., which ensures minimization of work in process and design optimal load of production on the basis measured and analyzed times operations of production. Part of thesis is the design layouts of workplace with selection of optimal variation which provides shortening and better overview on flow of material production.

Rationalization of production casing
Konečný, Jan ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
The thesis deals with the reorganization of production injection pump casing, when the existing production solution, using cutting lines, did not meet the requirements for flexible manufacturing. There are handled points leading to the replacement of the line of machining centres after a brief introduction of the company. Among the main points of thesis are the design of operations, choice of tools and cutting conditions, proposal clamping device and technology, techno-economic evaluation of the newly introduced production.

Rationalization of the production line
Straka, Jiří ; Štipčák, Jaroslav (referee) ; Osička, Karel (advisor)
This masters thesis optimises production of the step plates (which are parts of the sliding steps systems used in tramways, subways, hi-speed trains etc.) to increase the production rate to meet customers demand. The purpose of the work was reached by detailed analysis of the production process followed by evaluation of the results which led to the list of the possible solutions. The solution with the greatest time improvement was chosen and explained in detail.

Rationalization of machining technology
Plančar, Jakub ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This diploma thesis is focused on a design of rationalization solutions for machining workplace in Siemens Company. The machined pieces are shafts, the basic components of the electric motors. The introductory part of this study describes the theoretical basics of machining technology, especially milling. The next part is focused on the company presentation, the analysis of the existing workplace and its technologies and components. In the following section are selected weaker production sites, and then is presented opportunities for improvement and rationalization of this workplace. Following the elaboration of the selected rationalization solution, along with techno – economic evaluation of the production change, which highlights the results of this study.

Rationalization of a part production
Bartl, Lukáš ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
The assigned thesis is focused on the proposal of rationalization solutions to the component Bonnet, which is a standard representative of the most important sections of broader spectrum of customer´s components. The introduction part describes the component basis, according to which the standard representative was chosen, later on characterised from the point of view of seriality. The following large part of classfying the time comsumption in machinery is essential for the calculations as such, which are the essential part of this dissertation. The proposal of production rationalization is concerned with the exclusion of unnecessary losses and using existing ressources with the help of a higher level of machinery, technology, work organisation, production and management, which lead to a higher labour productivity. The technological production preparation ensures the documentation processing, the proposal of semi-finished product, machines, fastening, measuring and calculation of necessary technological specifications for ensuring the production. In the final part, there is to be found the technical and economical evaluation of rationalization proposals, which numerically evaluates the analysed outputs of this thesis.

Rationalization of grinder body production
Mišelnický, Lukáš ; Osička, Karel (referee) ; Prokop, Jaroslav (advisor)
The thesis is focused on the rationalization of the grinding body production as a special accessory for a vertical lathe with the type designation BASICTURN 1250 from the company TOSHULIN PLC. The thesis describes the problems of the current production and suggests the constructional and technological adjustments in order to achieve a reduction of the production costs and the overall production efficiency.
