Technology of productive milling on CNC machines
Trunda, Jiří ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
Objective graduation theses, is determining and propound optimal alternate manufacturing section servant as base of electron microscope. As a production method is used chippy cutting on numerical controlled machine behind by the help of usage progressive cutting tools. To construction control program was use 3D CAD/CAM system of Solid Vision, Ltd. Corporation. Product working is complete project and procedure on manufacturing section, that is in finish well-founded technoeconomic evaluation.

Biological Signal Generator
Kadeřábek, Jan ; Čech, Petr (referee) ; Sekora, Jiří (advisor)
This semestral thesis describes signal EKG, it’s origin, evaluation and device for his generation. After identification with standard course of EKG signal, was such as signal created in program language Matlab. It’s consisting of 10 sinus courses, where each of them has it’s own frequence, start phase and amplitude. Each of this part of EKG signal is beat frequence variant. Rates of it’s durations and sizes were fixed from medicin literature. Such as created program were rewritten to program language C and is basic of main program, which control signal processor. Finally was propoused preparation, which will be generated this signal. Outcome of this thesis is teoretic treatise about signal EKG, created program for generation of this course include part control and machine doing realization of biological courses.

Design of the fixture for the clamping of the machined part
Pilař, Radek ; Kubík, Roman (referee) ; Strejček, Jan (advisor)
Bachelor’s thesis is focused on design for clamping of machined part on CNC machine EC-1600. Familiarization with issue, including a theory that is necessary for desing and manufactrure of the fixture. There are made design of options fixture, calculations of cutting forces, clamping forces, verification of safety and economic evaluation. The aim is to create the documentation that discusses all information regarding to a proposal fixture clamp of managment of the compandy OMNI-X CZ.

Standardized procedure of the machine tool adjustment for change of the machined part type
Nedoma, Tomáš ; Tuna, Jaroslav (referee) ; Lošák, Petr (advisor)
The bachelor thesis at hand is dealing with standardized procedure of machine adjustment in process of machined rail type change in Bosch Diesel s.r.o. Jihlava. In the thesis, procedures of external adjustment of preparations that clamp workpieces into machining centers and overall procedure of machine adjustment are described. The elaborated standardized procedures are included in instruction manuals, which are used by workers of the company for machine adjustments. These “manuals” shall minimize occurrence of defective steps in the adjustment process and prevent their interchange. Mistakes based in incorrect procedure of the workers lead to prolongation of the time necessary for machine adjustment in process of change of machined type by up to hundreds of minutes per month. Bosch Diesel s.r.o. has adopted these instruction manuals and thanks to them shall save couple of tens of thousands euro per year.

Solution drilling technologies and clamping units
Adam, Jan ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
This Bachelor's Thesis introduces drilling technology, construction of clamping for specific component and its examination in terms of technology and economics.First part of Bachelor's Thesis deals with technology of drilling and with instruments for drilling such as drills and reamers. Next is survey of particular types of drilling machines. Second part of this Thesis is about rules for construction of clamping units and their disposal. Analysis of componet for which is clamping unit constructed. Following by construction of drilling gauge,comparing of incidental times with using the gauge and without using the gauge and finally calculation of investment return in to clamping unit.

Custom-made production upon a vertical CNC machine
Okáč, Petr ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
The thesis focuses on the topic of custom metalworking, which is familiar to author due to his experience in the field. The first part describes advantages and disadvantages associated with business of small and middle companies, their role in economy and everyday problems they need to solve. The second part compares the manufacturing of a steel part on CNC machine to manufacturing it using conventional machines and evaluating possibilities for custom manufacturing.

Designing of equipments for machining of high pressure pump housing.
Trutna, Pavel ; Janský, Milan (referee) ; Zemčík, Oskar (advisor)
The goal of this work was engeneering of new equipment for cutting operation in focus on new type of High Pressure Pumps CP3. Based on criteria from point of view of ergonomics, machining, shape of the housing and costs, equipment has been engeneered which allows to clamp and finish cutting of the required surface on the housing. Equipment designing has been perfomed in 3D CAD software which is able to provide with drawings and 3D data.

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.

The device for measuring of camshafts timings
Jozíf, Lukáš ; Mazal, Pavel (referee) ; Mazůrek, Ivan (advisor)
Bachelor’s thesis is focused on constructional concept of device for measuring of camshafts timing and its wear-out. After short introduction and definitions of basic concepts there are problems of cams design analyzed and overview of the commercially offered devices is mentioned. Next part focuses on construction of the proper device including design documentation. Procedure of measuring with the device and example of some data evaluation is described. In the conclusion I evaluated constructional and economic aspect the whole concept.
