Grinding of Bearing Rings
Růžička, Daniel ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The main objective of this work is to evaluate the surface quality, machined on three different grinders (all three from different age), and to compare those grinders. Comparison is done by the achieved degree of precision of measured geometric tolerances in inner orbits of the outer bearing rings. As the best grinder is expressly marked the newest (type CNC) however, the second in a row (the second youngest) is very close to its quality and finally it is noted that the purchase and operation of this grinder is more convenient.

Wire electrical discharge machining at production of tools for working of wood
Sedláček, Jiří ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
My thesis is aimed at the application of wire electical discharge machining technology in the production of woodworking tools. All of this in the conditions of Vydona company. There is a theory of machining method plus a well-aranged division of cutter tools for wood in the introduction. The practical part describes in detail the procedur of cutting shaped plate out of tungsten carbide. As a result of the technical and at the same time the economic evaluation is an establishment of hourly rate for machine.

Unconventional Technology of Wire Electrical Discharge Machining.
Svoboda, Jiří ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
This thesis deals with technology of electric discharge machining with emphasis on application of the principle of material removal on wire cut electric discharge machine. The main part is concentrated on wire cut electric discharge machining in terms of a small tool making shop. The goal of the thesis is to create a wire cut electric discharge machining workplace in the company with a focus on the production of cutting tools. The thesis defines requirements for each component of cutting tools and strategies for their machining. Machining of model part and subsequent technical - economic evaluation is included in the final part.

Manufacturing of Gearwheels Using Various Technologies
Řezáč, Matěj ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The present bachelor thesis is focused on the production of spur gears. The theoretical part summarizes the information related to toothing, its production and inspection. In the practical part, three technologies of spur gear manufacture are selected the gears are made. Finally the thesis compares the spur gears produced by these technologies geometrically and dimensionally

Rationalization of a part production
Bartl, Lukáš ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
The assigned thesis is focused on the proposal of rationalization solutions to the component Bonnet, which is a standard representative of the most important sections of broader spectrum of customer´s components. The introduction part describes the component basis, according to which the standard representative was chosen, later on characterised from the point of view of seriality. The following large part of classfying the time comsumption in machinery is essential for the calculations as such, which are the essential part of this dissertation. The proposal of production rationalization is concerned with the exclusion of unnecessary losses and using existing ressources with the help of a higher level of machinery, technology, work organisation, production and management, which lead to a higher labour productivity. The technological production preparation ensures the documentation processing, the proposal of semi-finished product, machines, fastening, measuring and calculation of necessary technological specifications for ensuring the production. In the final part, there is to be found the technical and economical evaluation of rationalization proposals, which numerically evaluates the analysed outputs of this thesis.

Optimization and use of standardized manufacturing routines for the Common Rail Flange production of high pressure pumps.
Doležal, Jan ; Prokop, Jaroslav (referee) ; Píška, Miroslav (advisor)
Objective of the Project of optimization and introduction of standardized procedures in flange production is to plan, determine and introduce optimal procedures based on time scan and MTM analysis; to determine standards, to establish standardized procedures for multi -machine operation and visual control and to train personnel according to new procedure. Project is expected to stabilize process, decrease work in process production, improve quality and increase volume of flange production to 2200 pieces per day for one production line. Furthermore to provide comparison of standardization influence on operations in flange production process, to perform quantitative analysis of several working instructions on visual control workplaces by statistics method (R&R study).

Trends in use of non-conventional technology for electrical discharge machining.
Mouralová, Kateřina ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
The aim of this dissertation are future trends of electrical discharge machining in conditions of a small tool factory. In the introduction is presented the theory of non-conventional machining. The practical part is focused on valuation the current level of electrical discharge machining, the importance of the use in a tool Nástrojárna Ryšavý. It also compares the level of leading global manufacturers of electrical discharge machines and future trends of electro-discharge technology.
