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.

Production of check valve's part
Růžička, Pavel ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
The bachelor's thesis deals with the production innovation of the return valve disc component used in pumping technology. It is a component made of sheet metal with 3 mm thickness, the quality of material is according to ČSN 11 320. Existing production using cutting technology in a process tool will be replaced by a modern, more accurate and especially more economical method by precise cutting with a pressure edge. Based on the literature study of precision cutting, assessment of production technology and processing of design solutions, the cutting tool was designed to be able to significantly speed up and reduce the cost of production of the component. It will be placed in a three-acting press from Feintool, namely XTF Speed with a nominal force of 1500 kN. In the final technical and economic evaluation, it was proved that the newly designed technology is able to bring a component of the same nature to the market, but at a significantly lower price.

The manufacturing of metal shim by fineblanking process
Uttendorfská, Magdalena ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
This master´s thesis is concerning the problem of manufacturing technology of the metal shim, which is a part of automobile brake mechanism. Shim will be made of the S460MC steel and the expected production series is 800 000 pieces per year. This quantity, demanded quality and accuracy of blank are the main reasons for application of fineblanking technology process with pressure edge. The blank will be making by triple–action press produced by Feintool, marked HFAplus4500LT. This press produces two blanks per one action.

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.

Manufacturing of Component by Fineblanking Technology
Čeryová, Lenka ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This bachelor thesis is focused on the design of production technology of the friction plate for the automatic gearbox DSG. Before selecting the most suitable technology for the production of friction plates the evaluation of different available technologies was carried out, of which as the most appropriate method, the accurate cutting with pressing edge was selected. The friction plate will be manufactured from metal sheet with the thickness of 1.5 mm, steel 12040, which will be supplied in coiled sheets. From the technological calculations followed that the friction plate will be produced in a one manufacturing operation. For serial production the machine HFA 3200 plus with the maximum force of 3200 kN was chosen. The main objective of the bachelor thesis is designing of cutting tools, creation of drawing documentation and technical - economic evaluation.

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.

The Machines and Tools for the Fineblanking Technology
Šindelka, Marek ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This work provides a brief overview of the used machines and tools designed for fineblanking. Fineblanking is a technology from the field of the surface forming, suitable especially for mass production, which can be used to make a functional component in a single operation. This work also lists the various methods of precision cutting, and describes the tools, that are the main reason for the quality of the product. Furthermore, in this work are listed some examples from today in practice used machines and their planting into the entire complex of production lines.
