Cutting components with higher accuracy to size
Steiner, Jaromír ; Varjan, Matúš (referee) ; Žák, Ladislav (advisor)
The main topic of this thesis is the fineblanking technology with a vee-ring which was chosen as the most suitable solution. The aim is a design and an assessment of technologicity of the selected component, a draft of the structural design of the tool and an economic evalua-tion of the project. The chain wheel has been designed from structural steel 11500; parameters have been evaluated as appropriate. The instrument has been designed as two-station progressive tool for single-row layout of the fineblanked parts with a moving punch; the vee-ring is positioned both to the blanking plate and to the vee-ring plate. The press was chosen on the basis of the calculated shearing force by Feintool Company. At the selected batch 500,000 units, 5.1 CZK per fineblanket part has been calculated.

Manufacturing possibilities of motorcycle brake wheel
Rozum, Josef ; Dohnal, Ivo (referee) ; Podaný, Kamil (advisor)
This bachelor thesis presents a variant solution of mass production of motorcycle brake wheel. These are part of rotating component of large diameter and small thickness made up mainly of carbon steel. The thesis presents methods for the production of unconventional machining technologies and methods of molding. As appropriate variants were selected technologies of laser cutting, water jet cutting, plasma cutting, blanking and fineblanking. The individual methods are described and evaluated their suitability for production. For fineblanking method which seems to be optimal is indicated the production process.

Production form-parts by cutting
Hansen, Petra ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The thesis elaborated in an undergraduate degree in Manufacturing Technology, proposes a technology for cutting form parts. The specified component is made from 3 mm sheet metal. The material component is structural steel EN S235JRG1. Based on the literature study, several possible methods of production parts are described. After evaluation of the required accuracy, surface quality and yearly volume of production (100 000 units / year) the technology of fine blanking has been chosen. For the production of components will be used: Triple hydraulic press, HFA 3200plus, made by Feintool. Cutting tool has been designed with moving punch, and the tool contains standardized parts. The economic comparison has been made between the methods of precision cutting, trimming and unconventional classic laser technology.

Manufacturing of driving chain gear
Řiháček, Jan ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This thesis deals with the production of driving chain gear, made from sheet metal 14 220.3, with a thickness of 8.0 mm. Set production series is 150 000 pieces per year. After the analysis of possible production methods was choosed fine-blanking technology as productive metod. It was elaborate the proposal of technological solution and constructional design involves selecting of the appropriate blank (sheet metal 8 x 1250 x 2500 mm), design of cutting tool with its documentation and the choice of production machine (triple-action hydraulic press Feintool HFA 3200 plus). In the last part of thesis was done an economical evaluation to assess the efficiency of the production.

Manufacturing of cutter wheel for brush saw
Hanáček, Jakub ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
The project is submitting design of technology production of the part from the sheet iron 12050, thickness of 2 mm and production run of 120 000 pieces per year. From the proposed options of manufacturing was determined that the fineblanking technology by vee ring is the most advantageous. The fineblanking manufacture was designed for fineblanking tool which is set on the hydraulic press HSR - 630 X - TRA from producer SCHMID with nominal force 6300 kN. Functional parts of tool are produced of tool steel 19 437. According to economical calculation it was defined the price of the manufactured part on 61,4 Kč.

Manufacturing possibilities of slider
Chládek, Martin ; Havliš, Stanislav (referee) ; Podaný, Kamil (advisor)
Project drawn up as a part of bachelor studies of mechanical engineering branch brings suggestion of technologies that are usable for manufacturing of slider, which is a part of turn restrictor mechanism produced by the company TOKOZ, and presents assessment of its suitability. Considered technologies are casting, metal injection molding (MIM), combinations of non-conventional methods of material separation and bending, conventional cutting and bending, cutting and roll forming and precision cutting and bending. Upon a comparison of attributes of these technologies especially in term of precision requests, one piece manufacturing expenses and manufacturing time demands was chosen as the most suitable option with regard to productivity combination of conventional cutting and bending and with regard to manufacturing precision combination of precision cutting and bending.

Precision blanking of components
Augste, Jakub ; Samek, Radko (referee) ; Žák, Ladislav (advisor)
The project elaborated in frame of bachelor's study programme B2341–3 is submitting literary pursuit of technologies production of the fineblanking components. This thesis is concerned with a problem of the fineblanking in mass production, concretely development, principle, technological direction, tools, presses and cost-effectiveness of fineblanking. The thesis was also compared differences between conventional stamping and fineblanking. Methods suitable for small-lot production are described only marginally.

Forming Technology of Thin Sheets
Musil, Zbyněk ; Žák, Ladislav (referee) ; Dvořák, Milan (advisor)
This bachelor‘s thesis deals with technology of mechanical working of the sheetmetals by cutting for rotary and non-rotary single parts. The first part deal with common dissertation about surface mechanical working, mainly about cutting and meaning of cutting gap in accordance with final cutting. The second part deals with transfer of the new pieces of knowledge from foreign technical literature of surface mechanical working. In the last part there is done an aplication on the particular component.
