Efficiency Improvement of Grinding Technology Using Construction Adjustments
Koláček, David ; Prokop, Jaroslav (referee) ; Sedlák, Josef (advisor)
This thesis is oriented to technological and design direction. It is focused on the upgrading of existing machinery from a structural perspective. There is studied the impact of design modifications to the existing production process from a technological point of view. This thesis is specifically concentrated on the technology division of the material, especially on the technology cutting-off in dry condition. There is examined the ability of self-sharpening cutting tools and the quality of the final product under varying input conditions. The job is finished by the carried out techno-economic evaluation, where are compared the costs of the structural adjustments in comparison with mechanical equipment, that could be purchased on the market. The thesis is finished with overall analysis of the optimal efficiency of the production process.

Production and grinding/sharpening of cemented carbide tools
Prokeš, David ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis concerns the description of rotary tools made of cemented carbides. Ce-mented carbides appear as wide range tool material with reference to ductility, hardness of material and relatively low cost. New knowledge of cemented carbide manufacturing has still improved mechanical characteristics of this material. Tools made of cemented carbides are made on modern 5 axis CNC tool-making grinder machines which can be easily set with grinding parameters and interaction with measuring tools for quick parameters changeover. All of these qualities are suitable for serial and also piece tools production.

Machining technology of external threads
Kabrda, Martin ; Osička, Karel (referee) ; Prokop, Jaroslav (advisor)
This bachelor's thesis focused on "Thread cutting technology" complexly deals with the individual types of threads, their designation and their use in practice, including norms specifying their standardization. There are also described methods of machining of external threads, which include cutting, turning, milling or grinding. The last chapter describes methods of economic comparison of individual machining methods.

Rationalization of grinder body production
Mišelnický, Lukáš ; Osička, Karel (referee) ; Prokop, Jaroslav (advisor)
The thesis is focused on the rationalization of the grinding body production as a special accessory for a vertical lathe with the type designation BASICTURN 1250 from the company TOSHULIN PLC. The thesis describes the problems of the current production and suggests the constructional and technological adjustments in order to achieve a reduction of the production costs and the overall production efficiency.

Manufacturing of Welded Components
Podsedník, Jaroslav ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
This work describes changes related to the transition from manual welding to robot welding selected component within the product range of the company, in which the author works. The aim was to determine the time that you return investments in new technology and what will be savings for the planned production volume. Both points were met.

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.
