Production of Pattern Equipment for Casting Pump
Suchomel, Martin ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis focuses on the design of foudry technology, design and production of pattern equipment for castiong of pump from cast iron ČSN 42 2420. The practical part elaborates design of technology and pattern equipment in CAD system SolidWorks. Simulation of casting was made in CAE system ProCAST. For design of milling technology was used CAM system HSMWorks. On the CNC machines was machined model, core box and underlay. Result of my thesis is pattern equipment for moulds and cores for the casting. In the end was made molds, cores and five samples of casting was casted.
Cost-effect and technical comparison of nonconventional technologies AWJ and LBM with the view of needs of a company
Malát, Jan ; Dvořák, Jaromír (referee) ; Slaný, Martin (advisor)
This study deals with unconventional materials cutting technology with a fo-cus on abrasive water jet cutting and CO2 laser. The thesis is divided into theoretical and experimental section. The theoretical part describes principles and functions of nonconventional technologies, the basic division and practical applications. The practical part is focused on choosing the best technology with the production of samples and their subsequent comparison. The thesis recommends producer and type of the machine which best meets requirements on basis of the test results.
Solution of modernization technology of part air-pump
Černý, Michal ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
The subject of this thesis is modernization of manufacturing process of air-pump component in a specific company. The work is focused on designing a new variant of the manufacturing process for mass production of the given component. The introduction evaluates the technology of product manufacture and describes the existing technologies of performed prototype production. The second chapter introduces a machine-tool, which will play the existing role of production, which will streamline the productivity of work, reduce the risk of human error and improve the quality of manufacturing accuracy. Further new tools are selected and a new production technology is designed. In conclusion, machine times and an overall design of production are evaluated.
Machining of stainless steels
Perončík, Martin ; Dvořák, Jaromír (referee) ; Humár, Anton (advisor)
Bachelor thesis is specialized to solving of problems of stainless steels machining. There is carried out the analysis of stainless steels in term of marking, chemical composition, physical and mechanical properties. In the following it deals with analysis of machining, spe-cification of geometry and material of cutting tools and cutting conditions.
Problems CNC machines: Magazine, spindle, change of tools
Stoupenec, Jan ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
This bachelor´s thesis deals with automatic tool change in a CNC machine. In the introductory part, types of tool storages and basic principles of tool change are described. Next part deals with description of spindle types. In the last part, suitable machines for the manufacture of four different model parts are chosen.
Production of gears model on FDM printer
Frátrik, Michal ; Dvořák, Jaromír (referee) ; Zemčík, Oskar (advisor)
This bachelor thesis deals with an issue of 3D printing of gears. In the first part are concisely summarized processes of 3D printing, selected types of Rapid Prototyping considering the FDM and properties of materials used in this method. The second part deals with a suggestion of gears model based on the gearbox of the kitchen blender. Gearbox was designed in 3D modeling program Autocad inventor 2013 and printed on the Reprap printer Sinuhed. There is techno-economic appreciation of production of the model in conclusion.
Cutting operation of cover parts.
Kobliha, Lukáš ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
In This thesis is elaborated a proposal for the manufacture of specified parts of the cover. The The work contains an analysis of components and analysis of possible technologies usable for the production, including concretely selected machines and tools. Elaborated is also a technological process, manual for to work on a lathe, and the theoretical number of units produced per year, depending on the shift working consumption indexable cutting inserts for turning.
Production of interior car handle prototype on 3D FDM printer
Kaššák, Marek ; Dvořák, Jaromír (referee) ; Zemčík, Oskar (advisor)
This bachelor this processes the issue of manufacturing of a prototype of handle for the car interior using method fused deposition modeling method. First part of this is dedicated to a brief overwiev of prototype manufacturing using rapid prototyping technology , with FDM 3D printing and materials used by FDM method. Second part is dedicated to design of 3D model using AutoDesk Inventor 2014 software, prototype manufacturing itself, evaluating of construction technologicality and technological-economic evaluation of manufacturing costs.
Effect of the diameter of the nozzle on the 3D printer print quality
Kutil, Jaroslav ; Dvořák, Jaromír (referee) ; Zemčík, Oskar (advisor)
The matter of this thesis is to find the influence of the diameter of the nozzle on the 3D printer´s print quality. The first part briefly characterizes the Rapid Prototyping technology and describes the RepRap project. The second part describes the construction of the experimental FMD 3D printer. The following section deals with technical printing parametres and their influence on the printed product. The experimental part of the thesis is focused on the impact of the discharge nozzle diameter on the mechanical properties, surface quality and shape accuracy of the final product and on the following recommendations of operational parametres.
Analysis of piece part production of the clutch unit
Menšík, Jan ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with piece production of a given component. The purpose of the bachelor thesis is to analyze the existing manufacturing process and to make suggestions for its upgrade in terms of reduction of production costs in repeating piece production. During the bachelor thesis research and writing, an incorrect naming of the manufactured component was detected and a more suitable name was proposed. Suggestions for upgrade of the existing manufacturing process were presented in the company and offered for implementation.
