Automatization of production technologies status monitoring
Molent, Michal ; Číka, Petr (referee) ; Krajsa, Ondřej (advisor)
The bachelor thesis focuses on with a description and design of automated surveillance over operation of production technologies from the initial collection and processing of information to the presentation of the results in the company´s intranet and their archiving. In the first part the proposal is described theoretically with possibilities of advanced solution of the given issues. The second part occupy of with the initial proposal for the solution. The third part is focused on the implementation of the prototypical implementation of an automated surveillance for application in an industrial environment. The Fourth part focus on testing all system, which is used in two factoring halls D and E.

Characterisation of chosen types of dairy products
Musilová, Lenka ; Buňka, František (referee) ; Vítová, Eva (advisor)
The aim of this thesis was to design technology of production soft cheese with white mold on the surface in a pilot plant conditions using unpasteurized milk that comes from grazing cows. This way I wanted to be closer to the traditional cheese manufacturing technology, over which today dominates the industrial. Final cheeses were subjected to sensory analysis in order to determine their acceptability for ordinary consumers. Sensory evaluation was carried out by two committees: students and seniors. Between the two committiees were noticeable differences, however, both commissions at the conclusion assessed the cheese as „good”. This evaluation was mainly based on lower ratings of taste (flavor) of the samples, which were quite strong and unusual for Czech consumers.

Comparison of pasta manufactoring in Europe and Asia
Píšťková, Magdalena ; Vránová, Dana (referee) ; Vespalcová, Milena (advisor)
This bachelor thesis deals with differences between manufacturing technologies of European and Asian noodles. First part concentrates on wheat as a basic raw material for noodle production. Structure and chemical composition of wheat grain, growing conditions, Triticum durum are described. Next part considers wheat flour, the most important product made of wheat, its manufacturing, storage, defects, and kinds. Semolina made of Triticum durum wheat is mentioned. In more detail it concentrates on classification and manufacturing technology of pastes booth in Europe and Asia. Further it considers other raw materials used and also additives that are used in order to improve nutritional value, color, and taste of final products. In conclusion there is a summary of differences among raw material and the additives used in pasta and noodle production. Lastly the manufacturing technology comparison of European pastes and Asian noodles is done.

Solution CNC technology of part whit a CNC-unit Sinumerik
Forbelský, Jiří ; Madaj, Martin (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis elaborates complete manufacturing process of a shape shaft. Technological procedure is designed in two variants. The practice variant employs tools, material and CNC lathe available at university workshop. The designed technological procedure has been verified by manufacturing the shaft. Series production utilizes modern tools and an industrial lathe. Both the described variants are compared and evaluated.

Innovation of manufacturing of helical flute
Janištinová, Edita ; Burda, Jiří (referee) ; Slaný, Martin (advisor)
The thesis is focused on the technology of manufacturing of helical flute in the frame servomotor of austenitic chromium-nickel steel with improved machinability. One part of this thesis is a theoretical analysis of stainless steel and more detailed analysis of machined steel SANMAC 304L. The thesis also analyzes the current way of machining in the company VUES Brno s.r.o. and suggests new innovative ways of manufacturing helical flute. Innovative proposals include a technological procedure and a choice of instruments and tools for turning and milling. The means of manufacturing are evaluated from an economic and technical point of view. Conclusion of this thesis contains the assessment of the current way of machining with innovative designs.

Solution production of a component to mould
Veselý, Vladimír ; Jaroš, Aleš (referee) ; Kalivoda, Milan (advisor)
This thesis describes creation of a packaging component made of ABS-TPU material. It is being made by vacuum shaping technology on a negative form. Bosch Diesel s.r.o. Jihlava company is introduced in the first part and a brief summary of the most commonly used packagings follows. The next part shows the very first draft of packaging shape and also how customers and the manufacturer implement some final changes. Next part describes the process of making a form and the packaging fabric. Finally there is aneconomical evaluation in the last part.

Losses Analysis of Induction Machines with Small Output Power
Mach, Martin ; Záskalický, Pavel (referee) ; Voženílek, Petr (referee) ; Hájek, Vítězslav (advisor)
The main objects of this doctoral thesis are analysis of a small induction motor losses and research of ways how to reduce losses and increase efficiency of this motor. The ways how to reduce losses and increase efficiency under study are as follow: reduction of stator winding’s resistance, lengthening of magnetic circuit, modification of turn number, cooper squirrel cage, slots shape optimization, sheets annealing and use of sheets with lower specific losses. The losses analysis and the research of ways how to reduce losses are done due to laboratory work. For this laboratory work, eleven different samples of the motor with above mentioned modifications were manufactured. Results of their measurements and losses analysis are presented in this thesis. There were also simulations by finite elements method used to help solve objects of this thesis. Due to the simulations, analysis of loses of the induction motor under study was done. Results of this analysis include some details that are not included in the results from measurement, for example separation of core losses between rotor and stator. The simulations were also used for analysis of manufacturing technology impact onto the motor’s performance. During this analysis, following impacts were considered: actual shape of magnetic circuit, stator’s sheets riveting, influence of cutting onto material’s properties and placement of the stator into conductive frame. Results of this analysis are presented in this thesis.

Solution technology of part "víko" in the condition of a middle-sized company
Kavan, Petr ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The diploma thesis is concerned with evaluation of actual production technology of part “hydraulics cover” and with design of new, progressive variation machining of this part. Solution is focused at first on rationalization of cutting tools and choice of suitable cutting tools. An effort is to achieve shorter production time and decrease costs on production of component. With this problem is related alteration of technological documentation and technical economic evaluation for determination return rate of investments into progressive cutting tools.
