Types and characteristics of precision cutting methods
Hrtús, Vojtěch ; Císařová, Michaela (referee) ; Štroner, Marek (advisor)
Bachelor thesis deals with methods of precise cutting and their analysis. The methods used for production of small series were discussed only briefly due to their small occurrence in practice. In the case of fine blanking, an extensive search is made regarding the individual parameters influencing the quality of the shearing process. Furthermore, the work also deals with the shortcomings of the method and possible ways to modernize the technology, either in terms of quality of the shearing process or in terms of economy.

Production of guiding disc
Slavík, Tomáš ; Peterková, Eva (referee) ; Císařová, Michaela (advisor)
The bachelor's thesis is focused on the design of the production of a guide disk made of sheet metal DC01 with a thickness of 3 mm. The production series is set to 100 000 pieces per year. Due to the required accuracy and size of the series, it was chosen that the guide disk will be made by the method of fine blanking. A coil of sheet metal has been chosen as the semi-finished product due to percentile of material usage and size of the series. For production will be needed a total of 24 coils of sheet with length of 308 m and one incomplete coil with a length of 132 m. The total force was calculated as Fc = 887,3 kN. Due to this strength, dimensions of the sheet and floor area of the tool, a triple-acting hydraulic press FEINTOOL XFT 1500speed was chosen for the production of the part. The last step was to check whether the size of the series is profitable or lossful. It was calculated that production becomes profitable at 49 554 pieces. Due to the size of the series, it can be stated that the production will be profitable.

Production of sunshade's part
Obořil, Filip ; Harant, Martin (referee) ; Císařová, Michaela (advisor)
The work deals with the design of the manufacturing technology for the lateral covering fabrication of the sunshade. The part will be made of aluminium ČSN 42 4004 with thickness of 2mm. A manufacturing series comes to 100 000 per year. Some different manufacturing technologies were analyzed and the most suitable of them - the technology of fine-blanking with pushed edge was chosen. It was chosen the vertical laying of components on a sheet of aluminium roll. For production the servomechanical press XFT 1500 speed from FEINTOOL company was selected. In conclusion, economy of chosen manufacturing technology was evaluated.

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.

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.

Production of form-parts by cutting
Tomášková, Veronika ; Hušek, Martin (referee) ; Dvořák, Milan (advisor)
The thesis elaborated in a master's degree programme Manufacturing Technology and Management in Industry proposes a technology for cutting form parts. The part is made of steel EN S235JRG1 (ČSN 41 1373) with 3 mm thickness. Based on literature review with a respect to yearly volume of production (100 000 pcs/year) and surface quality has been designed new technology of fineblanking for manufacturing of the part. For the technology of fineblanking have been made technological analysis and the tool has been design regarding to the chosen fineblanking press Feintool X-TRA 320. The conclusion of the thesis deals with technical-economical evaluation of manufacturing process and also has been compared the price of the part using unconventional production technology.

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 cylinder holder by fineblanking technology
Piterka, Miloslav ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The thesis is focused on production of a cylinder holder, which has been made from stainless steel 17 240. The product is 6 mm thick and there are 200 000 pieces produced per a year. After analysis of manufacturing technology there has been selected fine-blanking technology with v-ring for production of these components. For this reason there has been developed a study. Then there have been evaluated the technological and control parameters of the components. There has been selected the single row arrangement on the sheet of tin and chosen a stock of blank metal sheet for manufacturing with strict measurements (8 x 1 000 x 2 000) mm. There has been made the suggestion of design of a cutting tool. Hydraulic press Feintool HFA 8800plus has been selected for the final production. Eventually there has been evaluated the economics of production of fine-blanking with v-ring due to break even point.
