Functional failures dependance to measuring system of assembly lines DRV 2.
Barták, Pavel ; Pernikář, Jiří (referee) ; Zemčík, Oskar (advisor)
The Bachelor thesis is focused on assembly of pressure regulation valve (DRV) which is part of injection system Common Rail produced in company Bosch Diesel s.r.o. The purpose of this thesis is to consider the possibilities of assembly process effects, components for failures when functionally checked and suggestion of solution to minimize them. After practical part there was focused on assembly process to get necessary data. On the base of these data direction of analysis was followed, as the measurement of claimed components in Bosch Diesel laboratories. After the evaluation the countermeasures were proposed which some of them were implemented in production and subsequently analysed.

Roller burnishing tools in engineering.
Henzl, David ; Zemčík, Oskar (referee) ; Zemčík, Oskar (advisor)
This bachelor work deals with chipless technology of roller burnishing and tools with bearing on roller burnishing of circular orifices and back-to back surfaces. In the first part of the work elementary conections concerned with finishing and hardening of machine components by roller burnishing are explained. In the next part the classification of tools produced by German company Baublies AG is realised. In the following part there are examples of roller burnishing method utilization in the machine industry. Hereafter, the technical – economical evaluation and comparation with conventional methods of finishing such as lapping, honing, superfinishing, polishing, grinding, core – drilling and reaming, boring work, diamond burnishing and shot peening is realised. In the conclusion of the work the assumptions for the future are given.

Alternative measurement of shape and position deviations for needs of incomming inspection.
Jaša, Aleš ; Pernikář, Jiří (referee) ; Zemčík, Oskar (advisor)
This thesis deals with a possibility how to make a check of purchased components faster at the incoming inspection of the Bosch Diesel s.r.o. (Co., Ltd) and perhaps even how to save investment in new machines during expanding of production without quality compromises during the check itself, so that everything would proceed according to ISO/TS 16949 standard, valid for an automotive industry. The whole practical part has been elaborated on the basis of measurements done at the incoming inspection measuring laboratories and in cooperation with QMM1.2 department. The results have been evaluated by statistical software qs-STAT ME 6 by Q-DAS company.

Implementation of tool data management in firm TIRAD.
Dohnal, Tomáš ; Zemčík, Oskar (referee) ; Janák, Miroslav (advisor)
The aim of this thesis is to suggest a conception of implementation of Tool Data Management system into Tirad metal-working company. The first part of the thesis suggests a way of integration of Tool Data Management into a greater complex of implemented measures named Cybernetic Space for Production Control and Planning. Subsequent parts deal with the implementation itself. The final part lists presumptive technical and economical effects on the operation of Tirad company.

Rationalization of manipulation of material in Bosch Diesel s.r.o.
Novák, Jaroslav ; Zemčík, Oskar (referee) ; Hlavenka, Bohumil (advisor)
This bachelor thesis is engaging in problems with location of machines and work places and material flow in workshop for remanufacturing of high pressure injection pumps in plant of Bosch Diesel Ltd. in Jihlava. Impulse for build-up of this bachelor thesis is planned expansion on new type of pump and unsuitable location of machines and work places and general unsuitable solution of production area. At designing of rebuilding of this workshop was used of experiences of staffs from Industrial engineering department (TEF6), Facility management department (FCM) and Remanufacturing department (MFB). Objective of this bachelor thesis is the best solution of current problems and elimination of future problems. Everything with the lowest cost for rebuilding. Result of this bachelor thesis is proposal of two variants of solution. Proposal nr.1 contains economic solution and proposal nr.2 contains solution with ideal material flow. This bachelor thesis is recipe only, for responsible people, how to change current status.
