Finishing tool manufacturing
Rušín, Filip ; Kouřil, Karel (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with the production of a finishing instrument for roughing three different diameters. The first chapter introduces the selection of the required material, the semi-finished product design and the heat treatment of the product. The following is determination of the production conditions and compilation of the technological process and drawing. At the end of this work there is an evaluation of the technical-economic aspect and a discussion about possible upcoming situations.
Vibration at machining of metals - reasons and remedies
Sismilich, Vladimír ; Kouřil, Karel (referee) ; Píška, Miroslav (advisor)
This diploma thesis is concerning about summarizing and describing types of vibrations, their causes and influences to the machining. The stable conditions of machining were pointed out. The experiment was conducted in which the frequency response function of specific milling machine was measured. Than the stability lobe diagram was constructed.
Optimisation of Selected Technological Processes in the Production of Bearing Components
Otoupalík, Jan ; Čep, Robert (referee) ; Sadílek, Marek (referee) ; Kouřil, Karel (referee) ; Chladil, Josef (advisor)
The dissertation is focused on the optimization of technological processes in the production of the outer bearing ring. The first part of the research was focused on the latest trends in the production of bearings. In the experimental part the technological processes of production were analyzed from the choice of the semi-finished product to the optimization of finishing technologies for machining the outer diameter of the bearing ring.
Cutting Performance of Cemented Carbide Tools with Nano-Crystalline PVD Coatings
Hudeček, Pavel ; Kouřil, Karel (referee) ; Píška, Miroslav (advisor)
This thesis deals with the analysis of properties of hard coatings and wear resistance PVD coated technology. It focuses on the preparation, execution and evaluation of test coatings on the front ball milling cutter.
The Study of Productions Operation Management
Petřek, Martin ; Kouřil, Karel (referee) ; Jurová, Marie (advisor)
The thesis dwells about methodics of processing an order in the company: Hardening shop Frydrych s.r.o. while respecting all the demands on the technological process of thermal and thermo-chemical manipulation as annealing, tempering and cementing. On the bases of the analyse and documental procedures the thesis is unraveling a concept for elimination of absences in the sphere of processing the order also as booking, invoicing and evaluating.
The development of new axial tools with edges of various cutting materials on defined diameters for the machining of precision and high-precision openings
Dostál, Martin ; Plíšek, Jiří (referee) ; Kouřil, Karel (advisor)
The first part of work provides definition of basic parameters of accuracy, quality of machined surface and accuracy requirements for the holes. Further work includes a description of the reamers and drills according to the technological, material, geometrical and structural aspects. Subsequently is described range of the largest drills and reamers manufacturers, focusing on a combination of different cutting materials. The practical part contains the development of high-precision drill, which takes advantages of combining two following cutting materials hard metal and cermet.
Cermets
Kontšek, Marián ; Plíšek, Jiří (referee) ; Kouřil, Karel (advisor)
The main motive and objective of this work is to summarize and supplement informations related to materials of cutting tools, particularly cermets, their chemical, physical and mechanical properties of the latest knowledge of current trends and offer of these cutting materials. In more detail will be discussed especially reamers of cermets.
Design and Manufacturing of a Prototypical Assembly of an Inline-four Engine Using Rapid Prototyping Technology
Al-Kheir, Raduan ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
Bakalářská práce se zabývá tématem prototypování a tvorbou 3D modelu jako součásti procesu produktového vývoje. Prototypový model motoru je konstruován s využitím parametrické aplikace CATIA v5 a vyroben s použitím aditivní výrobní technologie– metoda Fused Deposition Modeling. Teoretická část práce se věnuje problematice produktového vývoje, aditivní výroby a řadou konstrukčních a funkčních charakteristik motoru. Praktická část práce pak popisuje proces návrhu a výroby prototypového modelu motoru. Práce je ukončena technicko-ekonomickým zhodnocením navržené sestavy.
Production of Preparation Prototype Using Additive Method of Fused Deposition Modelling
Sedláček, Milan ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
This thesis focuses on the production of a product using the increasingly popular additive technologies Rapid Prototyping. The theoretical section explained the very rapid prototyping technology and its application in various sectors. There were also mentioned different materials to use for 3D printing and actual printing method. The practical part was focused on the prototype modeling in SolidWorks CAD software and the subsequent production of elements of the 3D printer uPrint, using additive method Fused Deposition Modeling. In the conclusion, there is the evaluation of prototype production and also cost comparison using alternative materials.
Evaluation the Cost of Cutting Tools for Milling Aluminium Profiles in IFE-ČR, a.s. Company
Němečková, Monika ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
This bachelor's thesis was written as part of study branch Economics and Process management on the Faculty of Business and Management in Brno. The first part is focused on the theoretical foundations. The second part contains an analysis and assessment of the overall cost of cutting tools for milling aluminum profiles in the company IFE-CR, practical analysis is based on the selected doors profile using the existing cutting tools and the newly deployed advanced cutting tools to reduce overall costs, time savings and productivity of production.
