On the optimization of machining process of the rotary part
Benda, Martin ; Sedlák, Josef (referee) ; Píška, Miroslav (advisor)
This thesis deals with analysing component manufacture of valve lines. Firstly evaluating current condition of production including determinated manufacture times and costs. Secondly carrying out inmprovement proposals for manufacture and optimalisation of cutting conditions while considering the minimal costs given for operation sections. The final provision summarizes results which were achieved and overall benefits of the thesis.

Automation of machining of the aluminum castings
Filistein, Jakub ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
The diploma work focuses on designing an automated machining, finishing and assembly line. Described in the chapters are the current technology of production, suggestions, the choice of a new solution and a technological-economical evaluation including capacitive and costs of running the production line and a comparison with the current technology. The result is proof that the return of the investment is roughly in one third.

Options for increasing the efficiency of small motors.
Kusý, Karel ; Janda, Marcel (referee) ; Hájek, Vítězslav (advisor)
This bachelor thesis concerns itself with the possibilities of achieving higher efficiency of small asynchronous motors and their manufacturing costs. The following chapters describe the design, function and principles of speed regulation of the asynchronous motor. Next, losses that occur during motor operation and ways of reducing them, are described. The last chapter of the thesis addreses factors that influence the manufacturing costs of the asynchornous motor and evaluates the material costs of one modified motor.

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.

Calculation of Production Costs in the Company Tomasek Milan - TOMEX
Neubauer, Ondřej ; Goth, Ondrej (referee) ; Luňáček, Jiří (advisor)
This thesis is focused on the calculation of production costs with the introduction of licensed production of submersible sludge pumps in company Tomasek Milan - TOMEX. The aim of this work is the introduction of licensed production and determine the manufacturing cost. In the theoretical section describes the methods for determining a production layout, calculation methods and methods of return on investment. The practical part deals with the determination of a suitable arrangement of production, production calculations and evaluation of overall investment.

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.

Parts of steam piston engine in relation to their price and operating costs
Uryč, Jan ; Kracík, Petr (referee) ; Škorpík, Jiří (advisor)
This thesis describes structure and working priciple of steam piston engine. The basic construction parts are included and divided according their function. Next it contains prediction of production costs of small steam piston engines with piston valve - simple expansion engine and compound engine. Then the coparison of parameters, production and operating costs of both engines follows. Finally there is mentioned a influence of buying the technology for the steam production and condensation such small units.

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.

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.
