Application of Additive Method of Fused Deposition Modeling to Production of Sprinkler Head
Jandák, Lukáš ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
The thesis is focused on the design, modeling and manufacturing of a prototype sprinkler using modern additive technology Rapid Prototyping. The model was created using parametrical software SolidWorks, made ready to print by Cura software and printed in A602 3D printer working on Fused Deposition Modeling method. The theoretical basis of the work is involved in Rapid Prototyping, CAD systems technology, description of additive materials and their applications. Conclusion of this work compares this method with other options of production and evaluates which method is more efficient and more economical.

Production of RC Airplane Model Propeller by a Mechanical Copying Machine
Krátká, Romana ; 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 of RC moulding, milling and chosen economic indices. The second part contains an inland market survey concerning selling of propellers of RC models. Then it is focused on an evaluation and project of a money saving alternative of manufacturing of these propellers (material: wood) using designed and modelled 3D copying machine.

DEVELOPMENT OF TOOLS WITH PCD, CVD LAYER AND CVD COATING FOR BORE FINISHING
Ćmiel, Milan ; Humár, Anton (referee) ; Kouřil, Karel (advisor)
The aim of the thesis is to design, conduct and assess an experiment seeking to look into the utility properties of recent tools manufactured by HAM-FINAL. The tools include polycrystalline diamond (PCD) and CVD diamond cutting edges. In the theoretical part, the attention is devoted to cutting materials with an emphasis on diamond materials, as well as to issues associated with the wearing of the cutting tools, requirements specified for precision of bores and tools used in the manufacture of precision bores. The paper further provides an overview of a selection of world’s leading manufacturers of PCD blanks, CVD diamond coatings, CVD diamond layers and reamers with PCD cutting edges.

Analysis of the Impact of Technological Processes on the Properties of the Functional Areas of Bearings
Fišerová, Zuzana ; Čep, Robert (referee) ; Sadílek, Marek (referee) ; Kouřil, Karel (referee) ; Chladil, Josef (advisor)
The dissertation is focused on the bearing production technology issues. The aim of the thesis is to investigate and evaluate the influence of the technological processes on properties of the functional surfaces of an outer bearing ring. The development, rolling, grinding and turning have been selected as basic technological processes. The subject of the surface integrity research on test samples is the measurement and analysis of the quality of the machined surfaces and residual stresses in the surface layers of the bearing rings. The comparison is made in relation to the previous operations - rolling, turning and grinding.

Marketing strategy proposal
Jánský, Radek ; Kouřil, Karel (referee) ; Chalupský, Vladimír (advisor)
The goal of this Diploma Thesis was the detection of the potential trends of manufactural and business activities in manufactural division AZ KLIMA, Ltd and to suggest the appropriate measures .The starting situation of this company is described in an extensive analytical part. The output is a summary of its strenghts and weakness aspects, opportunities and threats. The suggest of strategy is presented by an extended marketing mix. The emphasis is placed first of all on product sphere. There are mentioned technological and organisational impacts of commencement of production of bolting and welding ducts, spiral tubes and ending distribution elements. Afterwards there are suggested methods of economy in manufactural process, market targeting and personal impacts. At the end there are outlined the time-dependent implementation harmonogram of suggested strategy, feasibility control and evaluation of expected benefits.

Resistance of Sintered Carbides against Thermal Crack Spreading
Smrž, Peter ; Plíšek, Jiří (referee) ; Kouřil, Karel (advisor)
This thesis aims to compare the relationship of physical-mechanical properties of tool materials made of WC-Co sintered carbides with their resistance to initiation and propagation of thermal cracks. The paper presents the results of testing the basic physical-mechanical properties of the three samples sintered carbides with different percentage of Co binder. Next, this thesis describes the progress and results of quench experiment and cutting tests using, which was described resistance of the tested samples to thermal and mechanical shock, depending on the values of physical-mechanical properties.

Use of High-pressure Cooling System for Long-turn Machines
Kinc, Jiří ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
The thesis describe high-pressure cooling system and present experiment, when is using this cooling technology for turning cylindrical workpiece to long-turn machines. Workpiece manufactured using high-pressure cooling system is compares with Workpiece manufactured using low-pressure cooling system. Results are analyzed, evaluated and plotted in a single graphical relationships. The thesis is completed the analysis, discussion and recommendations regarding the using of high-pressure cooling.
