Vliv konstrukce pilového kotouče na proces dělení aglomerovaných materiálů konstantní podávací silou
 Poukar, Martin
This thesis focuses on the influence of the number of teeth on a saw blade on the cutting process of wood chipboard and wood fiberboard. It investigates how the number of teeth affects different parameters such as cutting force and specific cutting resistance. The experiment was conducted using four similar blades with varying numbers of teeth under constant feed force. The conclusions show that the cutting force per tooth linearly increases with decreasing number of teeth on the blade, and the specific cutting resistance exponentially decreases with decreasing number of teeth. These results are consistent with the literature assumptions. To select a suitable saw blade, it is necessary to consider multiple factors.

Vliv modifikace bukového dřeva na parametry obrábění
 Vencl, Jakub
The Bachelor´s thesis is focused on the observation of effect of beech wood modification on the energy parameters of chip machining. It is about a comparison of modifications of beech, i.e. Lignamon and Bendywood which will be compared to native beech. In the case of native wood, the results of experimental measurements were also compared to results calculated with conventional methods. The methods which were used were: Technological-statistical and Analytical method. The primary investigation was cutting force. It was found that modification of beech wood does not have a statistically significant effect on machining parameters. In a comparison of two theoretical methods in the case of native wood was found that the Technological-statistical method had better sameness with experiment. The disadvantege of those methods is that they cannot be used for modified wood.
