Production of gear wheel
Tesař, Michal ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
The work deals with the design of gear production technology and the required production series is 80,000 pieces per year. After evaluating various variants of gear production, the method of fine blanking with a vee-shaped was chosen, on which the literature search is also focused. The part will be made of material E 295 with a thickness of 2 mm and the semi-finished product is a coil of sheet metal. Part of the work is also the design of a tool, which is based on technological and control calculations. A three-acting press from the company Šmeral Brno FMB 440 was chosen as the machine. At the end of the work, an economic evaluation was performed.

Manufacturing of the Motorcycle Rosette
Radnický, František ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
This bachelor thesis is focused on design of suitable technology of motorcycle sprocket, made from sheet metal 11 500 with a thickness of 6 mm. The production series of this component is 100 000 pieces per year. Before selecting the most suitable technology for the production of rosette the evaluation of different available technologies was carried out, of which as the most appropriate method, the accurate cutting with pressing edge is selected. The technological and constructional solution is elaborated, which involves selecting of the appropriate blank (sheet metal 6 x 2000 x 4000), design of cuttingg tool with its documentation and the choice of production machine triple-action hydraulic press Feintool HFA 11000 plus. In the final phase, a technical and economic evaluation of the efficiency of the production is performed.

Manufacturing of chain wheel for BMX bike
Figar, Erik ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The thesis deals with the design of suitable technology for the production of BMX sprocket made of sheet metal 14 220.3, with a thickness of 4 mm. The production series is 200,000 units per year. Following the analysis of different production options, fine-blanking technology has been chosen as the most suitable precision cutting technology. A technological proposal has been created, which includes the choice of a suitable appropriate blank (sheet metal 4x2000x6000 mm) as well as the design of a shearing tool with the corresponding drawing documentation of its selected parts. On the basis of the calculated values, HFA 4500 plus hydraulic triple action press manufactured by the Feintool company was selected as a production machine. In the last stage, technical and economic assessment of the efficiency of this production was performed.

Cutting as a finishing operation
Bednář, Martin ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
The project elaborated design of technology production of the cutting by shaving operation. The component is made from sheet iron 11 321. Pursuant to of the literary pursuit a problem of the shaving and calculation was designed two operations of shaving. Recommended production choice was tool with nominal cutting force 173 kN in first operation and 68 kN in second operation.

Manufacturing of chain wheel for motorcycle
Šarocký, Robert ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The aim of this thesis was to propose a suitable technology for the construction process of a chain wheel, which is one of the parts of the drivetrain of a motorcycle. The production series was 200 000 pieces per year. An analysis of several different construction processes was carried out and the process chosen as the most suitable was exact cutting with compression edge. The material of the product was a metal plate (8 x 1000 x 2000) mm 14 220.3, with the width 8 mm.Furthermore, a proposal of a cutting tool was conducted with drawn documentation. Based on the calculation of the required powers the manufacturing machine was chosen, more particularly the three way hydraulic press Feintool HFA 8800 plus. In the final phase, an assessment focused on the effectiveness of the production process was carried out with focus on both the technical and the economic standpoint.

Fineblanking component and its manufacturing
Lata, Miroslav ; Peterková, Eva (referee) ; Šlais, Miroslav (advisor)
The diploma thesis deals with a propose of a new manufacturing technology of component called „KULISA“ drawing number 4-DP-05-10/01. The beginning of this work is prepared as a literary study about blanking. There are explained some basic concepts necessary to introduce a blanking topic. Other interest of this work is an assessment of actual state of conventional blanking technology which is being currently used for component production. With regard to the deficiencies of the existing method is proposed new technology of fine blanking. In the proposal is evaluated technological site of component construction and blanking tools are proposed with stress analysis included. Last part of the work deals with the economic evaluation, where is being compared efficiency of existing and new technology.

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.
