Optimization of projection activities in EPLAN ELECTRIC P8 software
Obšil, Martin ; Bastl, Jiří (referee) ; Polsterová, Helena (advisor)
The thesis deals with the optimization of project activities in the software EPLAN Electric P8. First part introduces electrotechnical software EPLAN, the basic functions, and explains the methodology of the work in the program environment. This is followed by an analysis of the state of the electrical documentation of the TAC 75 circular saw manufactured by Exactcut s. r. o., and the method of designing. The thesis is also focused on the individual problems that make barriers between the average and the high quality level of design and the ability to use the available features of the purchased software. Thereafter, individual optimization steps and partial methods of reaching aims are described. Part of the thesis is devoted to finding solutions for interconnection of two engineering branches, which are electric and fluid technologies and in the end are revealed expansion modules of software, which can be used to achieve a higher level of professional planning activity.

Diamond wheels and their use in the stone industry
Skryja, Jan ; Kolář, Ladislav (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis deals with stone sawing during stone processing. It is divided into theoretical and practical parts. In the theoretical part diamond blades, the sawing process and stone extraction are described. The practical part is focused on the wear of circular saws in granite circular sawing. The wear is determined for two diamond cutting blades made by different manufacturers and is determined by the blade weight loss and segments height loss as a function of time. Both measured values show linear dependence. The results are the basis for a future comparison of the two diamond blades on the economic side, which is not the subject of this work.

Conveyor with clamping and measuring
Polák, Aleš ; Koutecký, Tomáš (referee) ; Dvořáček, Jiří (advisor)
The first profile of the thesis describes current methods of segmenting and measuring of aluminium profile and analysis of a specific roller conveyor with a measuring device for feeding aluminium profile to a high-speed circular saw. The second section is focused on designing a new conveyor with clamps for feeding aluminium profile and designing measuring equipment based on the analysis in the first part.

Wood processing processes and problems of production technology of semi-finished products
Šimo, Samuel ; Osička, Karel (referee) ; Chladil, Josef (advisor)
The diploma thesis is focused on the optimization of a new production line of the woodprocessing factory DCP Timber. In the first part, the work approaches wood in terms of itsinternal structure and its physical and mechanical properties. The second part is focused on themost common methods of cutting the wood material. The third part describes the technology ofconvection drying of wood and the impact of this drying on the resulting quality of woodensemi-finished products. The practical part of the thesis is the solution to the inefficientproduction of the machine of the circular saw, which is an important part of the production line.There is a comparison of different cutting tools and their effect on dimensional tolerances. Inthe next point, thanks to mathematical models, the parameters of maximum feed speed andpower of the electric motor of the spreading saw are determined. Finally, a technical andeconomic evaluation is developed where the payback period is calculated in the case ofinvestment in a power unit with higher performance.

Design of Firewood Saw
Ferda, Tomáš ; John, David (referee) ; Rubínová, Dana (advisor)
This thesis describes a proposal for a rocker saw design. It addresses the general lack of current solutions, their description and it is drawing conclusions of these. The object of this thesis is to try to avoid potential problems which are being discussed in this thesis and therefore suggests solutions for enhancing the rocker saw, especially on the visual and ergonomic side.

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.
