Comparison of CMT TWIN with other MIG/MAG processes
Jiskra, Milan ; Felix, Michal (referee) ; Kubíček, Jaroslav (advisor)
The development of welding technology is constantly going forward mainly due to the reduction of production costs and the costs of additional straightening of weldments due to the welding distortion. Therefore, the leading producers of welding machine are coming with new methods and technologies. One of the innovations is also the tandem technology CMT Twin from the company Fronius. The experiment carried out in the diploma thesis confirmed that this is a very cost effective process. The CMT Twin is from the point of view of production costs of the weld cheaper variant and bring less heat into the material compared with conventional welding. Application equipment CMT Twin requires industrial robot, so the method is predestined for the series up to mass production. The CMT Twin finds application, for example in the automotive and shipbuilding industry.

Production of compressed air in the TZ Trinec
Kohut, Vojtěch ; Martinec, Jiří (referee) ; Fiedler, Jan (advisor)
The main purpose of this master’s thesis is description of the current technology of compressed air production in the grounds of Třinecké Železárny, a.s. (TZ). Compressed air for companies in the TZ area is manufactured and distributed by company Energetika Třinec, a.s. (ET). The part of the thesis is the preparation and execution of measurement including evaluation of specific energy consumption for production of compressed air by compressors of ET company. In conclusion there is proposed the possibility of substitution of compressors including the economic evaluation.

The order processing by firm with usage of project management
Cagášek, Tomáš ; Chrobák, Petr (referee) ; Jurová, Marie (advisor)
GÁŠEK Tomáš: The order processing by firm with usage of project management The project laboured within the field of study with the name "Production tech-nology and industrial management" describes some versions of the potential job order's progress in the manufactory at the firm "Speciální strojírna, a.s.". A customer asks for the batch production of the casts, that he will be order step by step for working in regular intervals. The part of the customer's plan is the optimalization of the production and the press of the price, that should be lower after the finishing of the production technology. Along with the correction of the price, a customer expects cutting of the delivery time with the fully quali-ty of the working. In the first version, without a wide preparation, is all working realized on the general-purpose machines. The second version focuses on the production with use of drilling jigs, that is constructed and produced by the firm itself. The input costs of this preparation at the production will be compensated with the major production times, that will be destage from the expensive borer to the cheaper drilling-machine. The last third version supposes setting of the CNC machining centres and therethrough it will be reach to huge saving of the major and minor production times by the working.

Solution technology multiple groove guide pulley.
Teplý, Radek ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
This essay discusses the production technology of multiple-grooved pulley and evaluates the technology of construction, the choice of the semi-product and their possible variations for production. The next aim is to describe the choice of production technologies, the selection of tools, the composition of technological process and the composition of different ways of chip removal during production. The essay also presents an economic of batch-production and it defines the optimal ways of production with regards to production costs.

Technology of Production single parts with multiple bend
Daňhel, Marek ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
DAŇHEL, M. Production Technology for Parts with Multiple Bends. Bachelor thesis, Combined form of bachelor degree programme ENGINERING, subject of study Manufacturing Technology, 1st form, 3rd year of study, academic year 2008/2009, study group 3K1. FME BUT Brno, Institute of Manufacturing Technology, Department of metal forming and plastics. No. of pages 47, pictures 32, tables 6, supplements 9. Bachelor thesis supervisor doc. Ing. Milan Dvořák, CSc. _______________________________________________________________ The project developed within the framework of the bachelor degree programme, subject of study B2307-00 Manufacturing Technology, submits a bending technology proposal for a part with multiple bends. The bachelor thesis presents a theory overview related to the forming operations comprising bending, a selection of suitable alternatives for the manufacture of the given part and the production sequence for this part. The design of the bending tool is made in accordance with valid engineering standards for forming operations. As the basis for production the project includes manufacturing drawings of the punch and lower die and the drawing of the bending tool assembly. Technical and economic evaluation and conclusions in respect of the proposed technology constitute a part of the project.

Legal and economic aspects of use of CNG and biogas in transportation
Yusupova, Regina ; Štěpánek, Petr (advisor) ; Černý, Pavel (referee)
Use of compressed natural gas (CNG) as an alternative transportation fuel is currently being supported in European Union and Czech Republic as well. Upgraded Biogas (or biomethane) with its chemical characteristics is to be considered as a renewable substitute of CNG so it can be used for the same purposes. Biogas is produced in biogas stations. Current legislation terminates the support of producers of electricity and heat from renewable sources, including biogas stations. The absence of governmental support will endanger their existence. Producing of biomethane and using it in transportation is an alternative option for the owners of biogas stations. The aim of this bachelor thesis is to conduct an economic analysis of biomethane producing costs. On the basis of the results obtained, we will be able to say whether producing od biomethane is reasonable in Czech Republic. Then we will try to establish whether the use of biomethane in transportation is possible according to Czech legislative terms or what possible legislative amendments should be implemented.

The concept evaluation of nutrition in the agriculture enterprise
HAVELKOVÁ, Jana
This thesis deals with the level of nutrition of dairy cows based on assessing the need for nutrients and energy in relation to the milk yield. Under operating conditions the system of nutrition and feeding is evaluated and also analysis of selected economic indicators of milk production has been conducted. The monitored indicators of nutritional and energy values are within permitted tolerance limit of recommended values.

Determining Production Costs of Hay Silage on a Chosen Farm
BEHENSKÝ, Luboš
The aim of the work is to determine production costs of hay silage on the Co-operative Farm Koryta. Based on assignment three plots, which the Farm owns, were chosen. The first plot has the LPIS code 9706/1, the second 9601/7 and the third one 9703. Total land area of the selected plots is 28,43 ha. Observation was conducted during the harvest in order to obtain desired data. Additional data were acquired from the accounting of the Farm. According to the gathered data calculation of production costs and analysis of the harvesting technology was carried out.
