Progress in technology of mold milling with coated profile tools
Doležel, Ondřej ; Bumbálek, Bohumil (referee) ; Píška, Miroslav (advisor)
This diploma thesis is involved in possible development of different types of milling molds coated with modern plows. The first part is devoted to an analysis of contemporary trends in forms production technology. The analysis includes the different types of machines and tools for making various kinds of molds and dies. Another part deals with design of dies for sheet metal shears. The thesis continues by design of the production procedure after heat treatment and finishing die by miling. For milling of die are designed miling tools, the NC program and the possible development of manufacturing the die using a new machining center and the possibility of production optimization. The penultimate point of the thesis is technical and economical evaluation of the direction of development and comparison of positives and negatoves of each method. At the final evaluation is all summed up.
Removal of oil aerosol from the exhaust air in a production hall with automatic machine tools
Štefánek, Stanislav ; Martinec, Jiří (referee) ; Charvát, Pavel (advisor)
This master thesis deals with the filtration of air contaminated with oil and the total efficiency and propose a new filtration system. The reason is insufficient capacity and functionality of the operating device is incorrect. It will propose the most appropriate solution to this in terms of economic and technical design is satisfactory.
Technology of Production Parts Console
Rusník, Tomáš ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This thesis describes the complete technology solution of front driving axle console production by machining. The console is part of the self-supporting structure of the tractor and is produced under conditions of large engineering company. Introduction describes the prduction technology of component. The main part is devoted to the technological process of production and selection of appropriate cutting tools. Technical and economical evaluation of machined part is mentioned in the conclusion of thesis.
Production of the Cylinder into the Injection Unit
Lexa, Josef ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
This work mainly focuses on the manufacture of the cylinder of injection unit as one of the two major components to the element and the injection unit to the injector pump before and after the heat treatment relative to the two alternatives of production, concentrating on the alternative of production on machining center. There are mentioned as the subsequent and finishing operations such as well as final assembly including mounting with a functional commissioning into the pump. There is also mentioned a production of samples of cylinder of injection unit, the proposals for improving and ecology of the whore production.
Building and control of 5-axis milling machines
Hekrle, Pavel ; Marek, Tomáš (referee) ; Holub, Michal (advisor)
This bachelor thesis deals with detailed description of acceptance tests of machining centers. The first part contains segmentation of geometric tolerances, which are used for geometric accuracy tests. A large part of this thesis is dedicated to these tests. The next part includes phases of preparations for acceptance tests as well as segmentation and progress of these tests. One part of the thesis is devoted to machine alignment. The last chapter contains detailed description and principle of some modern measuring devices which are used for acceptance tests.
Design of operator workplace of machining center
Kříž, Jan ; Pavlík, Jan (referee) ; Novotný, Tomáš (advisor)
The presented work contains the parameters and rules relevant for the design of the inter- face between the machining center and it's operator. All of information were obtained by search in scientific literature and technical standards and subsequently were sorted according to the elements to which they relate. The work contains the actual anthropometric dimensions, description of the interface elements with references to standards which relate to them. The study also shows an example of an optimized keyboard layout for machine tools and methods applicable to design the spatial layout of the workplace. In conclusion there is evaluate the state of currently available literature and technical standards.
Solution technology of machining of part in the conditions of middle company.
Šašinka, Ondřej ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
Evaluation and comparison of existing process-selected components to a modernized variant, which is focused primarily at reducing engineering time and expansion of production facilities with respect to cooperating companies. First introduced to the company and its scope, after machining, at the end of the technological documentation for the proposed manufacturing process and its evaluation.
Stiffness estimation at the machining head and the strength analysis of the moving parts of the machining center MCV 1220.
Zbožínek, Martin ; Houfek, Martin (referee) ; Vrbka, Jan (advisor)
Main objective of the work was to estimate the possibilities and the limits of elementary stress and strain analysis of the construction. At the beginning it was necessary to simplify the problem to the 1-D bar problem. The calculation was performed for three typical loading cases, namely for the middle and the border position of the machining head. The contact forces and momentums and the displacements at the machining head have been calculated. The obtained results were then used for the stiffness evaluation of the construction at the machining head. The strength analysis of the moving parts of the machinig center has been done, too. Modern software products (Autodesk Inventor, ProENGINEER, ANSYS Workbench, Maple, Mathcad, etc.) were used for the calculation. The results were compared with The Finite Element Method results.
Analysis of shaped part production by milling
Doležel, Ondřej ; Kalivoda, Milan (referee) ; Zemčík, Oskar (advisor)
This thesis contains the basic dividing of methods and ways of milling of shaped surfaces and subsequent analysis. In the following are contained the basic machinery and tools used in milling of shaped surfaces. Knowledge of the various methods are compared and recommended for use in practice.
Solution technology of production "Válec elementu vstřikovacího čerpadla"-part in condition firm Motorpal Jihlava.
Havel, Marian ; Polzer, Aleš (referee) ; Kalivoda, Milan (advisor)
This thesis is intended on optimalization of industrial process the barrel element of injection pump. Existing technology, mainly special-purpose machines, will be replaced with modern methods with utilization CNC turning machines and new efficient machines for finishing operations, especially for finalization the main hole of the barrel. Thereinafter it will be worked suggestions critical operations, which hands main function element and it is necessary their optimalization in light of work difficulty and ecology.
