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.

Analysis of the production process of HPL panels applied for playgrounds made by Kompan Inc
Vik, Michal ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
The theoretical part consists of the introduction of company KOMPAN A.S. In addition, there are also introduced the main parts of production, especially CNC workshop, shop floor workplace and warehouse. In the experimental part there is introduced HPL material first. The following is a description of the testing including used tools and materials provided by Kompan Czech Republic s.r.o. Testing was focused on measurement of force load of instruments using piezoelectric dynamometer. The obtained data was processed and analyzed. The last part of the master's thesis is economic evaluation of the production of selected product, which consist of HPL panels. In the following discussion there are evaluate obtained results. In the conclusion part are summarized main results.

Usage of Modern Technologies for the Design of the Production of Children's Puzzle
Sedláková, Eva ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
The bachelor thesis deals with the design and production of children's puzzle using modern methods and technologies. It characterizes the puzzle as a toy and its use, it as well describes the additive Rapid Prototyping technology, commercially available additive materials and their applications. The practical part describes the design of the individual parts of the puzzle in the SolidEdge parameter model and their production on a repro Prusa i3 printer. The last part of the bachelor thesis concerns with a technical- economic evaluation.

Effect of size impact on surface integrity while reaming with modern reaming head MT3
Rybařík, Jaroslav ; Kouřil, Karel (referee) ; Slaný, Martin (advisor)
The aim of this thesis is to design, implement and evaluate an experiment that verifies the influence the size effect on selected parameters of the surface integrity. For the experiment were used highly productive reaming head MT3 made by HAM-FINAL. Evaluation of the surface integrity was done in terms of the characteristics of the surface roughness, geometric tolerances and changes in microstructure. Furthermore, the influence of the depth of chips evaluated for changes in the feed force, cutting torque and changes in specific cutting energy. The theoretical part deals with the description of the size effect, characteristic reaming, surface integrity, preparation of material and identification of highly productive MT3 reaming head.

Sharpening and producing standard tools on a CNC grinder Walter
Martinek, Petr ; Kouřil, Karel (referee) ; Kalivoda, Milan (advisor)
This bachelor´s thesis presents a modern five-axis CNC machine HELITRNIC POWER from the company Walter Maschinenbau GmbH, which is designed for sharpening and production of rotary, cutting tools. The project provided the most commonly used types of tools, their materials and surface treatment (coating). Furthermore, there is described the production process and sharpening of tools using control software Tool Studio, when considered appropriate wheels and clamping devices. Finally, it provided an economic assessment of costly equipment.

Tool wear testing method of cutting tools with cermet cutting edges in turning
Koppová, Aneta ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
The diploma thesis deals with the analysis of the wear of tools fitted with cermet cutting edge. The first part is focused on the theoretical aspects of the problem, which are applied in the practical part. The aim was to perform cutting tests in which carbon steel was turned under selected cutting conditions. Tool wear during turning and the quality of the machined surface were monitored. Machining continued until the selected wear criterion reached the limit value. Two different cermets were tested and the measured data were the basis for the analysis of the wear of the tool edges and the determination of the tool life.

Concept of reaming technology
Štěpánek, Martin ; Sedlák, Josef (referee) ; Kouřil, Karel (advisor)
The diploma thesis deals with the design of the hole-making technology for hydraulic components that are specific for its high requirements on size and shape accuracy. The aim of diploma thesis is to compare the productivity, efficiency and accuracy of reaming with two different reamers – the solid carbide reamer and the newly designed reamer that combines two cermets on cutting part of the tool. In the practical part, the data analyses and calculations were made. It was discovered that the newly designed tool brings economic benefits while the qualities of final hole are improving or remaining at the same level.
