Machining of vulcanizing molds from aluminum alloys
Kaška, Zdeněk ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
This diploma thesis is focused on the issue of deep drilling of vulcanization molds from various aluminum alloys. The work will describe a brief description of machined materials and tools for deep drilling, including the production of the vulcanization mold itself. Based on experimental measurements, the analysis of data and knowledge gained from deep drilling of aluminum alloys with different silicon contents will be performed. In the end, the individual components of force loads for both machined materials will be compared
Efficiency Improvement Proposal of Production of Engineering Component
Cvrkal, Richard ; Kubů, Marek (referee) ; Sedlák, Josef (advisor)
The thesis is dealing with drilling deep holes. Theoretical part of thesis is focused on base knowledge of deep drilling. Experimental part deals with testing two different borers, with different cutting conditions and different purchase prize. Drilling was made into 1.2343 ESU material. Conclusion of this work is concept of purchase machinery for deep drilling.
The influence of geometry and cutting tool parameters on residual stress during machining of the pressure containers
Berka, Martin ; Kouřil, Karel (referee) ; Strejček, Jan (advisor)
This thesis deals with the influence of changes in cutting parameters and tool geometry on residual stress inside the material. I examine the influence by deep drilling. Changing the cutting parameters concerns the alteration of the tool feed and the pressure of the coolant during the process. The influence of tool geometry is studied by using two different single edge cannon drills. The research was realized in cooperation with Bosch Diesel Ltd. The theoretical part includes a description of the injection system, in which a high-pressure container is contained. The high-pressure container was used to evaluate the influence of the cutting parameters and tool geometry on residual stress. Furthermore, the theoretical part deals with the deep drilling technology used and the theory of residual stresses. The practical part shows the measurement parameters and the corresponding results. In the conclusion of this thesis, a technical-economic evaluation of the measurement is conducted.
Deep drilling of an aeronautical part
Klíma, Jan ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
Diploma thesis deals with problems about deep drilling of aeronautical part made of aluminum alloy EN AW 7075 T7351. This work is focused on the material properties component and current aluminum alloys processing. Further it contains a part delicated to various kinds of technologies of deep drilling, primarily is focused to gun drilling. Describes a tool, technology and conditions in gun drilling of deep holes with focused to analysis of the forces. Then it compares contemporary manufacturing technology of part drilling in cooperation and proposes an innovative technology of manufacturing. This project is accomplished with technical-economical evaluation.
Production of high-pressure feeder on Electric discharge machines
Doležal, Jiří ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
This thesis provides a short introduction to the electroerosion machining and its application to the production of a specific high-pressure feeder. Other possible options of production of the feeder have been considered and the best combination of the manufacturing method selected. Finally are recommendations of using other unconventional machining methods.
Domestic heat pump
Sobotka, Tomáš ; Pavlů, Jaroslav (referee) ; Pospíšil, Jiří (advisor)
This bachelor´s thesis dissert on heating hot service water for self-contained houses by the help of heat pumps. Forepart is engaged in explication of fundamental terms about heat pump and about it‘s the lowpotentional heat resources. Second quater is meted out proposal for self-contained house and its economic expediency as compared to electric boiler.
