Production technology of drill
Křehlík, Luboš ; Kolář, Ladislav (referee) ; Osička, Karel (advisor)
The work deals with production technology stepped drill of cemented carbides. Handles the basic methods and information technology grinding. Cemented carbides are becoming more frequent choice of material for processing in many industrial directions. They allow widespread use due to their mechanical and technological properties. Tools of this material are manufactured on a 5-axis grinding machines. The use of precision CNC machines enables efficient and accurate production of both simple and complex cutting tools. Software CNC machines allow you to control the 3D simulation before production begins, it's a convenient tool for checking the functionality of the program. It is also possible to establish the production of the subsequent dimensional control of the finished piece. These CNC machines and cemented carbide tools can be used for both serial and piece production.
New generations of PVD coatings
Kantar, Filip ; Kolář, Ladislav (referee) ; Jaroš, Aleš (advisor)
Bachelor thesis deals with methods of coating, cutting tools and a new generation of coatings. In the first part are listed and described basic coating methods. The next part is aimed on coating of PVD methods. In the third part are listed basic tool materials and their characteristics. The last part is focused on new generation of coatings, their application, properties and structures.
Design of Stirling Engine Operating at Low Temperature Difference
Gavač, Adam ; Kolář, Ladislav (referee) ; Sedlák, Josef (advisor)
The aim of this study is to acquaint the reader with the Stirling engine, which is one of the possible alternatives to generally known combustion engine. The theoretical part has three major purposes: First is to describe thermodynamics of the Stirling cycle in the range that is essential for comprehension of the engine`s operating principle. Second is to mathematicaly derivate expression for the efficiency of the ideal Stirling cycle. Third is to discuss each of the essential parts of the device. Concepts acquired in the theoretical part were employed to design a digital model in the parametric modeler Autodesk Inventor. Parts were manufactured by a combination of typical and progressive technologies. Engine was assembled and tested afterwards.
CNC Machine and Machining Range of the Threaded Parts
Pávková, Alena ; Kolář, Ladislav (referee) ; Kalivoda, Milan (advisor)
Bachelor work includes designing technological process for a particular component selected from a range of companies engaged in machining. Furthermore, the work deals with infor-mation about the programming of CNC machines and compiling NC programs build TPV documentation. The aim is to make technological processes for the production range of the company.
Analysis of heat treatment effect on dimension shift
Kunkela, Ondřej ; Jaroš, Aleš (referee) ; Kolář, Ladislav (advisor)
This bachelor thesis focuses on chemical-heat steel processing, mainly to the size change caused by the process itself. To look into the problem closely some samples from various materials and of various size have been made. The samples were measured before and after the ionic nitridation. Likewise the samples, the real peaces were measured, some of them were ionic nitridated and some were cemented. The real pieces were made from the same material but they differed in size and shape. Subsequently, all the figures were processed and assessed.
Recycling plastics for 3D printing
Hellebrand, Martin ; Kolář, Ladislav (referee) ; Zemčík, Oskar (advisor)
Purpose of this paper is analysis of basic Rapid Prototyping technologies including FDM. Technologies are compared in matter of possible recyclation of used materials. The largest recyclation potential appeared in case of FDM technology. There were conducted analysis of basic materials used in this method. Possible methods for recyclation were described. Finally, there were conducted economical analysis to evaluate viability of recyclation in case of FDM.
Chemical Machining Technology
Macháček, David ; Kolář, Ladislav (referee) ; Osička, Karel (advisor)
This bachelor thesis describes the most used methods of chemical machining in the industry. There are discussed the basic principles of particular methods, their advantages and disadvantages, as well as their best use in terms of economics. The properties of used chemicals and basic safety in working with them are also mentioned.
HSS milling cutters deposited by nanocomposite coatings
Ludvík, Radek ; Kolář, Ladislav (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis deals with nanocomposite coatings deposited on cutting tools of high speed steel. The paper describes the fundamentals of milling, tools for milling and their division and clamping. Gradually, there are analyzed problems of high speed steels (their classification, marking, properties and uses, chemical composition and heat treatment). Then there is described the main characteristics of coating methods (division of coatings into generations, surface preparation before the coating and PVD and CVD methods). The last part of the thesis focuses on the properties of nanocomposite materials and to companies dealing with their application to the high-speed steel.
Design and Production of External Aquarium Filter Prototype
Svoboda, Richard ; Kolář, Ladislav (referee) ; Sedlák, Josef (advisor)
This Thesis is about the design and production of an external aquarium filter prototype. My prototype uses the method of the method Fused deposit modeling. The filter model was designed in a 3D parametric software Solidworks and printed by 3D-Printer uPrint. The thesis describes how the issue of waterproofing printed parts is solved, and also how the appropriate thread (diametr 90 mm) is chosen for printing.
